Kidney Transplant, Sleep Disorder May Add Up to Trouble

November 19, 2009
Heart disease, stroke more likely for organ recipients with sleep apnea, study finds. Kidney transplant patients with sleep apnea are at increased risk for high blood pressure, heart disease and stroke, Hungarian researchers say.

The study of 100 kidney transplant recipients found that 25 percent had moderate to severe sleep apnea, a rate similar to that seen in kidney disease patients on dialysis awaiting a transplant. This means that both types of patients who have the breathing-related sleep disorder should be considered at high risk for serious heart-related complications, the study authors noted.

Moderate Drinking Guards the Heart

November 19, 2009
But protective effect can wear off at higher levels in men, study finds. A Spanish study has found that long-term moderate drinking decreased the risk of heart disease by up to one-third in men and to a lesser degree in women.

New Heart Attack Treatment Guidelines Stress Coordination

November 18, 2009
Getting patients to the right hospitals quickly is critical, experts say. There's a message for doctors, hospitals and communities in new guidelines for treatment of coronary disease and heart attacks: Get organized.

Every community should have an organized system of emergency care for heart attacks, including programs to identify patients before they get to hospitals and strategies for getting them to medical centers equipped to perform artery-opening procedures, say the guidelines issued by the American Heart Association, the American College of Cardiology and the Society for Cardiovascular Angiography and Interventions.

"The focus on integrated systems for patients with STEMI is important," said Dr.

Obesity Rolling Back Gains in Heart Health

November 17, 2009
Studies show risk factors rising among children and adults, with many denying they have a problem. Surging obesity rates, especially among children, may be putting the brakes on progress made in the past few decades against heart disease, researchers report.

And it doesn't help that many obese or overweight Americans still consider their weight "normal," as one study found.

One of several studies on the subject of obesity presented Tuesday at the American Heart Association (AHA) annual meeting in Orlando, Fla.

Finding suggests atherosclerosis is as old as the pyramids, and not an ill of the modern world. Hardening of the arteries may have more of a family history .

Heartburn Drugs Can Thwart Popular Blood Thinner

November 17, 2009
Combination can increase the risk of heart attack and stroke, U.S. officials say. Combining the antacid Prilosec with the popular blood thinner Plavix (clopidogrel) can cut the effectiveness of Plavix by half, putting patients at risk for heart attack or stroke, U.S. health officials said Tuesday.

Benefits of Eating Fish May Depend on Preparation

November 17, 2009
Baked or boiled beats fried or dried for heart health, researchers say. You'll get more heart-healthy benefits from omega-3 fatty acids if you eat baked or boiled fish instead of fried, dried or salted fish, according to a new study, which also found that adding low-sodium soy sauce or tofu is a good idea for women.

"It appears that boiling or baking fish with low-sodium soy sauce [shoyu] and tofu is beneficial, while eating fried, salted or dried fish is not. In fact, these methods of preparation may contribute to your risk," study author Lixin Meng, a doctoral candidate at the University of Hawaii at Manoa, said in a news release from the American Heart Association.

Moderate-Fat Diet May Be Better at Reducing Heart Risks

November 16, 2009
People with metabolic syndrome should steer clear of low-fat meal plans, study says. A moderate-fat diet may work better than a low-fat regimen for people suffering from metabolic syndrome, a collection of conditions putting them at higher risk for cardiovascular disease, new research finds.

"This is a good study that essentially confirms that the current recommendations are appropriate," said Alice Lichtenstein, a spokeswoman for the American Heart Association (AHA). "Since 2000, the AHA has been recommending not a low-fat diet, but one that is low in saturated fats and trans fatty acids.

Low Vitamin D Levels Linked to Heart Disease

November 16, 2009
But further trials are needed to prove this conclusively, researchers say. If your levels of vitamin D are too low, you may be at significantly increased risk for stroke, heart disease and death, a new study suggests.

Researchers followed 27,686 people, aged 50 and older, with no history of cardiovascular disease. The participants were divided into three groups based on their vitamin D levels: normal (more than 30 nanograms per milliliter), low (15 to 30 nanograms per milliliter), or very low (less than 15 nanograms per milliliter).

Why Watching TV Sports Increases Heart Attacks

November 16, 2009
For those who've had an attack already, stressful games raise blood pressure, study finds. Reduced blood flow to the heart may help explain why men who've had a heart attack are at increased risk for another while watching exciting sporting events, Chinese researchers report.

The study included 38 male heart attack survivors who watched live broadcasts of Olympic Games competitions or entertainment television programs. While the men watched the shows, their coronary artery blood flow to the heart was assessed by ST-segment analysis using continuous 12-lead electrocardiography, blood pressure monitoring and heart rate measurement.

Certain Reflux Drugs Tied to Higher Post-Angioplasty Death Rate

November 16, 2009
Study suggests interaction between Prilosec, Protonix and blood-thinners such as Plavix. People taking the acid reflux drugs Prilosec or Protonix in combination with blood thinners such as Plavix have a higher risk for death after angioplasty than people who don't take the two popular antacids, a new study has found.

The people in the study, which is to be presented Monday at the American Heart Association's annual meeting in Orlando, Fla., were undergoing what doctors call "percutaneous coronary intervention," or PCI, a common procedure used to widen a narrowed artery.

Migraine Increases Likelihood of Stroke

November 16, 2009
But risk is highest for women with aura, researchers find. People who suffer migraines have more than double the risk of ischemic stroke, and the risk is especially high in women, a new study has found.

Ischemic stroke, the most common type of stroke, occurs when blood supply to the brain is cut off by plaque accumulation or a blood clot.

In this study, researchers from Johns Hopkins University School of Medicine reviewed the findings of 21 studies that included a total of 622,381 men and women, aged 18 to 70, in Europe and North America.

Gene Linked to Breast Cancer Might Boost Heart Health

November 16, 2009
When BRCA1 is deactivated, it can lead to atherosclerosis, or hardening of the arteries, mouse study suggests. The over-activity of a gene known to boost a woman's risk for breast cancer may have a good side, making arteries healthier, a new study suggests.

The study, performed in mice, also found that when this gene, called BRCA1, is turned off, it promotes an inflammation that can lead to atherosclerosis or hardening of the arteries.

Although there has been no previous observation of increased cardiovascular death specifically in the large number of people who carry the BRCA1 mutation, there has been a surprising suggestion of higher non-cancer death in this population, noted study senior author Dr.

Sudden Cardiac Death Much More Likely to Strike Men

November 16, 2009
Males have triple the odds than women, study finds, and black men are especially prone. Men, especially black men, are at a relatively high risk of sudden cardiac death over their lifetime compared to women, a new study finds.

That lifetime risk in men aged 40 and over is one in eight, or 12.3 percent .

FDA Questions Safety of Caffeinated Alcoholic Drinks

Surgery Not Always Best for Narrowed Kidney Arteries

November 11, 2009
Study finds medication works as well in certain people, without the risks. People suffering from blocked renal arteries fare just as well when treated with medication as they do by having the narrowed artery opened and a stent implanted, British researchers report.

For Older Walkers, Faster Is Better

November 11, 2009
Those who stroll are more likely to die from cardiovascular disease, study finds. Highlighting the importance of staying fit in old age, a French study has found that seniors who walk slowly are three times more likely to die from cardiovascular disease than are fast walkers.

The researchers measured the walking speed of the participants .

Anemia Drugs May Cause Deadly Blood Clots

November 10, 2009
Study raises more concerns about common treatment for chemo patients. New research on cancer patients adds to the controversy surrounding anemia drugs such as Procrit and Aranesp, concluding that they increase the risk of venous thromboembolism, potentially fatal blood clots.

These drugs, called erythropoiesis-stimulating agents (ESAs), are commonly prescribed to fight anemia associated with chemotherapy and chronic kidney disease. Recent studies have linked them with increased risk of death, stroke and new cancers.

Common Infections May Contribute to Strokes

November 10, 2009
But researchers not exactly sure how pathogens raise risk of brain attack. Exposure to several common pathogens may increase the risk of having a stroke, a new study shows.

Led by Dr. Mitchell Elkind, an associate professor of neurology at Columbia University Medical Center in New York City, the research team found that the pathogens Chlamydia pneumoniae, Helicobacter pylori, cytomegalovirus and herpes simplex virus 1 and 2 may be implicated in accelerating arterial disease, which in turn increases the risk of stroke.

Obesity Seems to Alter Heart Structure

November 09, 2009
Result may be left atrial enlargement, study finds. Obesity is a major risk factor for left atrial enlargement, which increases the risk of atrial fibrillation, stroke and death, a new study shows.

Atrial fibrillation is the most common type of arrhythmia (an irregular heart rhythm or heartbeat).

Researchers analyzed data on 1,212 men and women, aged 25 to 74, in Germany who were followed for 10 years.

Will New Anemia Drug Top Current Treatments?

November 04, 2009
Designed for a rare condition, it might have a wider application, experts say. A new drug designed to treat patients with a rare form of anemia could possibly have wider applications, perhaps replacing other anemia treatments that have been linked to an increased risk of death, cancer and stroke, experts say.

The drug, Hematide, was successful in treating patients who have pure red-cell aplasia, a condition caused by antibodies to a hormone needed to produce red blood cells. It's a "devastating condition that many patients have died from and ties patients to blood transfusions every two weeks for the rest of their life," said lead researcher Dr.

Anemia Drug May Raise Stroke Risk in Kidney Patients

November 02, 2009
Use of Aranesp should be reserved for the most seriously ill, experts say. A drug designed to fight anemia appears to double the risk of stroke in patients with diabetes and kidney disease without substantially improving their quality of life, a new study finds.

Darbepoetin alfa, marketed as Aranesp and known as an erythropoiesis-stimulating agent (ESA), is often prescribed for diabetic patients with chronic kidney disease and mild anemia.

"The benefits we assumed we would have by treating anemia were less striking and the risks were more striking," said lead researcher Dr.

Fructose May Raise Blood Pressure

October 30, 2009
Drinking more than two sweetened sodas a day boosts risk of hypertension, study finds. Here's a new reason to put down that sugary soft drink: Research suggests that a diet high in fructose, a common sweetener, boosts the risk of high blood pressure.

High-fructose corn syrup is found in many processed foods and beverages. Americans consume 30 percent more fructose now than 20 years ago, and researchers have linked higher fructose consumption to the growing obesity epidemic.

Stroke Centers May Offer Best Shot at Recovery

October 29, 2009
Specialty facilities are more apt to give needed treatment, and faster, study finds. Stroke patients taken directly to a designated stroke center are much more likely to receive the clot-busting drug tPA than those taken to the nearest hospital, says a new study.

If given within the first few hours after a stroke, tPA (tissue plasminogen activator) can reduce stroke-related disability.

The study grew out of a citywide program in Toronto that trains paramedics to screen for stroke and to take stroke patients to one of three regional stroke centers.

Migraine With Aura Can Double Stroke Risk

October 28, 2009
Young women who smoke and use birth control pills are most susceptible, researchers say. Women who get migraine headaches with aura should stop smoking and using birth control pills because they may increase their risk of stroke, researchers say.

For people who suffer migraine headaches with aura .

Sleep Apnea Episodes May Trigger Irregular Heartbeat

October 27, 2009
Study found 18-fold higher incidence of atrial fibrillation, other arrhythmias. New research provides the first hard evidence that the characteristic snorting and gasping of sleep apnea can spur potentially fatal heartbeat abnormalities.

Previous studies have suggested an association between sleep apnea and cardiac arrhythmias but they had not established a cause-and-effect relationship, said study senior author Dr. Susan Redline, a professor of medicine at Case Western Reserve University in Cleveland.

Where You Put on Pounds May Influence Clot Risk

October 26, 2009
Big hips in women, wide waists in men spell trouble, study finds. The location of excess body fat appears to affect the risk of dangerous blood clots in veins, although that location differs in men and women, a new Danish study indicates.

The 10-year study found that bigger hips are associated with an increased risk of venous thromboembolism (VTE) in women but not men, while a wider waistline was associated with increased risk in men, according to a report published online Oct. 26 in the journal Circulation.

Adding Drug Doesn't Help Control Blood Pressure

October 23, 2009
No risk reduction for heart patients when ARB added to ACE inhibitor therapy, study finds. Adding an angiotensin receptor blocker (ARB) drug to help control blood pressure has no benefit for people with heart disease who already are taking an ACE inhibitor, a new study finds.

The so-called "meta-analysis" of 41 previous studies found that combination therapy seems no better than ACE inhibitor therapy alone and may be harmful.

Results of the study, funded by the U.

Coffee May Slow Liver Disease

October 23, 2009
Finding could be good news for those with hepatitis C, researchers say. Coffee slows the progression of advanced liver disease in people with chronic hepatitis C, new research finds.

The study included 766 patients infected with hepatitis C virus (HCV) who were asked to report their intake of coffee, green tea and black tea. The patients were seen every three months during the nearly four-year study, and liver biopsies were taken at 18 months and 3.

Fish Oil Supplements Don't Help Depressed Heart Patients

October 20, 2009
Those who took them with antidepressant fared same as those who didn't. In a surprise and not very welcome finding, researchers report that fish oil supplements do not ease depression in individuals who suffer from both depression and coronary heart disease.

Participants in the study, which is published in the Oct. 21 issue of the Journal of the American Medical Association, were also taking the antidepressant sertraline (Zoloft).

Stretching Test May Reveal Arterial Stiffness

October 09, 2009
Flexibility exercises belong in cardiovascular workout, experts say. Sit on the floor and reach for your toes. If you can get your fingers past them and you're 40 or older, that could be a sign that your arteries are flexible, researchers say.

In an unusual finding, new research suggests that flexibility, as defined by how far you can reach while sitting down, may be linked to the stiffness of your arteries.

Trial Shows Heart Attack Education Makes Little Difference

October 07, 2009
But new study design might change response times, researcher says. A study to tell whether educating heart patients about the symptoms of heart attack would make them respond faster when one happens has produced negative results, but the researchers say a few changes in trial design might make a second look at the issue worthwhile.

The research included 3,522 people with known heart disease in six cities in the United States, Australia and New Zealand. Half were given lessons on the symptoms of a heart attack and what to do when they occurred .

Mercury in Fish Linked to High Blood Pressure

October 05, 2009
But researcher downplays importance of effect. Although new research links mercury in seafood with high blood pressure, this isn't reason enough for most people to stop eating fish, the study leader says.

"The small increase of blood pressure due to methylmercury will never outweigh the benefits of omega-3 fatty acids," said Dr. Eric Dewailly, a professor in the department of social and preventive medicine at Laval University in Quebec and lead author of a report in the Oct.

Drug Combo May Prevent Heart Attacks, Strokes

October 02, 2009
'Inexpensive, well-proven medications' could have huge impact, expert says Giving daily doses of a statin and a blood pressure-lowering ACE inhibitor to people at high risk for a heart attack or stroke reduced their incidence by more than 60 percent in two years, researchers report.

People in the study all had diabetes or a history of cardiovascular disease, but the drug regimen probably could provide similar benefits to anyone vulnerable to cardiovascular trouble because of obesity, high blood pressure or simply old age, said Dr. R.

Half of U.S. Babies Living Today May Reach 100

October 05, 2009
Rising life expectancy shows no signs of slowing, researchers say. If current life expectancy trends continue, more than half of babies born in rich nations since 2000 will live to 100 years of age, and they'll have less disability than elderly people in previous generations.

That's the conclusion of researchers who found that increases in life expectancy evident in rich nations since 1840 show no signs of slowing.

"The linear increase in record life expectancy for more than 165 years does not suggest a looming limit to human lifespan.

Mini-Stroke Found to Precede 1 in 8 Strokes

September 29, 2009
Expert urges reliance on other predictive tools, but not all agree. Just one of every eight strokes is preceded by a milder interruption of blood flow to the brain, called a transient ischemic attack (TIA), a new Canadian study shows.

And because of that, the researchers conclude, such an attack is not the crucial warning sign that physicians need.

"The clinical implication of this study is that we cannot rely on the TIA as a warning signal to tell us to intervene to prevent a stroke because it is seen before only one of every eight strokes," said Dr.

Clot-Busting Therapy Under Review

October 01, 2009
Cardiologists looking at new generation of drugs as Plavix trial shows double dosage best for angioplasty. Even as they digest the latest news on what dose of the clot-dissolving drug Plavix is best during angioplasty, cardiologists are looking at the next generation of clot-busters that could replace Plavix.

Clot-dissolving therapy was the big buzz among cardiologists at last week's Transcatheter Cardiovascular Therapeutics conference in San Francisco, according to Dr. Daniel I.

Autoimmune Disorder Linked to Stroke, Heart Attack in Women

September 28, 2009
Smoking, birth control pills raise risk higher, research finds. Women under 50 with a certain form of the autoimmune condition called antiphospholipid syndrome are at greatly increased risk for heart attack and stroke, and that risk is even higher when these women smoke or take birth control pills, new research shows.

Antiphospholipid syndrome occurs when autoantibodies attach to cell membranes and interfere with the normal clotting mechanism of the blood.

In the study, researchers in the Netherlands analyzed data on more than 1,000 young women and found that those with a particular type of antiphospholipid antibody, called lupus anticoagulant, are 43 times more likely to suffer a stroke and five times more likely to have a heart attack than the general population of young women.

Women With Atrial Fibrillation Face Rougher Road Than Men

September 24, 2009
Attention to gender differences, though, can make a difference, study contends. Women with atrial fibrillation are significantly more likely to have a stroke or die than are men with the heart condition, a new study has found.

Despite this, the study suggests, women with the condition receive less medical attention than men.

Atrial fibrillation occurs when the two small upper chambers of the heart, the atria, quiver rather than beat effectively.

Lack of Vitamin D Linked to High Blood Pressure

September 24, 2009
Effect seen 15 years later, researchers report. Low blood levels of vitamin D in younger women tripled their risk of high blood pressure 15 years later, new research has found.

Vitamin D deficiency, defined as less than 80 nanomoles per liter of blood, was measured in 1993 at the start of the Michigan Bone Health and Metabolism Study, explained study author Flojaune C. Griffin, a doctoral candidate at the University of Michigan School of Public Health.

Fructose Boosts Blood Pressure, Studies Find

September 24, 2009
Tests in mice and men link sugar to hypertension and say time of day may matter, too. America's sweet tooth may be contributing to the ever-increasing number of people with high blood pressure.

Two new studies link fructose, the kind of sugar in soft drinks and many sweetened foods, to high blood pressure, which is a major risk factor for heart attack, stroke and other cardiovascular diseases.

"It raises the possibility that fructose may have a role in the pathogenesis of hypertension," said Dr.

Preventing Second Stroke May Stave Off Dementia

September 24, 2009
Not all agree, though, that biggest risk factor is the brain attack itself. The way to reduce the chances of developing dementia such as Alzheimer's disease after a stroke is to prevent a second stroke by concentrating on all the known stroke risk factors, a new British study suggests.

Two major findings emerged from an analysis of 30 previous studies that involved more than 7,500 people who had suffered a stroke, said Dr. Sarah Pendlebury, a senior clinical fellow at the Stroke Prevention Research Unit of John Radcliffe Hospital in Oxford and lead author of a report published online Sept.

Minorities Less Likely to Have Blood Pressure Under Control

September 23, 2009
Blacks have the highest readings, despite taking medications, study finds. Blacks and Hispanics with a history of stroke or coronary artery disease have higher blood pressure than whites, while Hispanics are less likely to be prescribed medications to control it, a new U.S. study shows.

With Fancy Coffees, Calories Can Add Up

September 23, 2009
Popular blended beverages may be 'weighing you down,' health official says. Love your afternoon pick-me-up? A blended coffee beverage might hit the spot but pack on the pounds, a new study suggests.

A survey of about 3,000 purchases from 115 restaurant chains in New York City found that servings of brewed coffee or tea average about 63 calories, even when some include milk and sugar. But get a blended beverage and you're looking at 239 calories on average .

Cost Savings Adds to Value of Preventing Chronic Disease

September 23, 2009
Avoiding diabetes, high blood pressure can add years to life, researchers say. Prevention of chronic diseases such as diabetes, obesity and high blood pressure improves the lives of older Americans and also reduces medical costs, study findings show.

Researchers looked at a group of 51- and 52-year-olds from across the nation and projected their future state of health and medical costs if they could avoid developing certain chronic diseases. In a 51-year-old, prevention of obesity would extend life by 0.

Angina Often Affects Quality of Life

September 18, 2009
New strategy for managing chest pain may be warranted, study suggests. Many people with chronic angina experience frequent chest pain that affects their quality of life, a new study finds.

Angina, a tightness or discomfort in the chest caused by narrowing of a coronary artery, can lead to heart attacks.

Australian researchers surveyed more than 2,000 chronic angina patients and found that 29 percent of them experienced chest pain at least once a week, despite receiving treatments such as medications, balloon/stent procedures and bypass surgery.

Middle-Age Heart Risk Factors Shorten Men's Lives

September 18, 2009
Smoking, hypertension, high cholesterol cut 10 years of life, study finds. Middle-aged men with risk factors for heart disease such as smoking, high blood pressure and high cholesterol are taking 10 to 15 years off their lives compared to men without these troubles, British researchers say.

Although death from heart disease has been declining, in part due to better control of cardiovascular risk factors and better care, this is the first study that looks at death from heart disease in terms of life expectancy, the researchers said.

"The good news is that all of us can make changes to live a healthy life," said lead researcher Dr.

Childhood Stroke More Common Than Thought

September 17, 2009
Study finds double the incidence reported previously. The incidence of stroke among American children could be two to four times greater than has commonly been estimated, a new study says.

Pediatric strokes are rare; even the new estimate puts its incidence at only 2.4 strokes per 100,000 person-years (person-years represent the number of years children were studied).

Blacks Fare Worse After Cardiac Arrest

September 15, 2009
Poor hospital care a big reason why, researchers say. Black patients who suffer cardiac arrest in the hospital are much less likely to survive than white patients, a new study finds.

Most of this disparity appears to result from the hospital in which black patients receive care, although other factors play a role as well, the researchers said.

"We know that survival after having a cardiac arrest in the hospital setting has always been historically low," said lead researcher Dr.

Diabetes Medications Don't Lower Inflammation

September 15, 2009
Metformin, insulin have little effect on risk factor for heart disease, study finds. In people with newly diagnosed type 2 diabetes, the glucose-lowering medications metformin and insulin don't appear to reduce the inflammation associated with heart disease, new research suggests.

Even though these medications helped reduce glucose levels, the researchers found they didn't affect inflammatory markers any more than a placebo drug did, according to a study published in the Sept. 16 issue of the Journal of the American Medical Association.

Most Adult Americans at Some Risk for Heart Disease

September 14, 2009
Surging obesity rates have reversed gains, and now less than 8% have no heart disease risk factor, study finds. Decades of steady progress against heart disease may be on the wane, experts say, with a new study showing that only 7.5 percent of Americans are now in the clear when it comes to heart disease risk factors.

The continuing U.

Implantable Defibrillators May Not Help Women With Heart Failure

September 14, 2009
Analysis of previous research found little benefit for female patients. Widely used implantable cardioverter-defibrillators may not actually help women with advanced heart failure.

A new analysis turns up no evidence that the devices, used to detect and then correct abnormal heart rhythms, actually lowered the risk of death among female patients, despite the fact that this is routine therapy for all patients with heart failure.

"We do not know of the benefits of defibrillators when used as primary prevention," said Dr.

Air Pollution May Raise Blood Pressure

September 14, 2009
Inhaling microscopic particles could raise risk of heart disease, study finds Breathing polluted air for even two hours can boost blood pressure, potentially raising the risk of cardiovascular disease in those exposed to smog, a new study suggests.

Although the increase may not mean much for healthy people, "this small increase may actually be able to a trigger a heart attack or stroke," study author Dr. Robert D.

Drug Offers Hope Against Tough-to-Treat Hypertension

September 14, 2009
As yet unapproved, darusentan works in different way than standard medicines. A new drug for people whose high blood pressure cannot be controlled by existing medications has done well in a pivotal trial, researchers report.

Substantial reductions in blood pressure were achieved with various doses of the drug, darusentan, for people who were still hypertensive despite trying three or more medications, said a report released online Sept. 13 in The Lancet.

Busy Roads Boost Blood Pressure

September 11, 2009
Study found those who lived near heavy traffic noise had raised readings. Living next to busy roads may be bad for your blood pressure, a new study suggests.

People whose homes are in earshot of engines rumbling, horns honking and brakes screeching have an increased risk of high blood pressure, researchers report in the Sept. 9 issue of Environmental Health.

Research Seeks Cause of Preeclampsia

September 10, 2009
Focus is system that regulates blood pressure and fluid retention in pregnant women. New research is shedding some light on the development of preeclampaia, a dangerous condition that can cause miscarriage and death in pregnant women.

"Preeclampsia is a very serious condition that affects seven to 10 percent of all pregnancies in the United States," study author K. Bridget Brosnihan, a professor at Wake Forest University School of Medicine's Hypertension and Vascular Research Center, said in a news release.

Severe, Lasting Depression Tied to Heart Patient Deaths

September 08, 2009
For those who have been hospitalized, risk may double over 7 years, research shows. Certain depressed patients who suffer from heart disease have nearly double the risk of dying over a seven-year period compared with other depressed patients, researchers say.

The patients most at risk are those who suffer from the most severe depression within a few weeks of being hospitalized for a cardiac event, such as a heart attack, and those whose depression doesn't get better within six months, according to study findings published in the September issue of Archives of General Psychiatry.

The study authors noted that about one out of every five people who survive a heart attack hit a patch of major depression over the next few weeks.

Stroke May Be Striking at a Younger Age

September 02, 2009
Almost half of cases occur before 65, study finds, and many younger patients aren't getting rehab. Stroke could be affecting Americans earlier in life than ever before, a new study suggests.

"Stroke is no longer an affliction of old age," said lead researcher Timothy J. Wolf, an instructor of occupational therapy and neurology and investigator for the Cognitive Rehabilitation Research Group at Washington University School of Medicine, in St.

Caffeine Without Healthy Diet Linked to Heart Risk

September 02, 2009
Atrial fibrillation patients seem to drink lots of coffee but don't eat right, study suggests. People who drink lots of coffee but who don't follow a Mediterranean-style diet are more likely to have atrial fibrillation, a new study shows.

Italian researchers asked patients who'd been recently diagnosed with the common heart arrhythmia to supply information about their dietary habits, including caffeine consumption. Their diets were compared with those of people without atrial fibrillation.

Sometimes Angioplasty Can Wait

September 01, 2009
Artery-opening procedure can be done up to 21 hours later with milder heart attacks, study shows. Many people who arrive at hospital emergency rooms with chest pains can wait as long as 21 hours for artery-opening angioplasty, even if an electrocardiogram (EKG) shows evidence of a heart attack, a new French study suggests.

There was no significant difference in key measures of heart damage and one-month death rates in the study of 352 people with the mild form of heart attack called non-ST elevation myocardial infarction between those who had immediate angioplasty and those who waited an average of 21 hours for the procedure, according to a report in the Sept. 2 issue of the Journal of the American Medical Association.

Oldest Heart Patients May Get Most From Warfarin

August 31, 2009
In atrial fibrillation patients, blood-thinning drug best for those at highest risk of stroke. Older patients, or those with a prior history of stroke, are most likely to get a benefit when using warfarin to treat atrial fibrillation, a common heart rhythm disorder, a new study finds.

Kaiser Permanente and Massachusetts General Hospital researchers also say the drug is especially beneficial for patients with multiple risk factors for stroke.

Atrial fibrillation, which occurs when the heart's upper chambers quiver instead of contract, affects more than 2 million Americans.

Surgery Better Than Angioplasty for Narrowed Neck Artery

August 30, 2009
British study finds a reduced risk of stroke afterwards. The latest results from the longest-running study yet confirm that surgery is better than artery-opening angioplasty in preventing strokes caused by blockage of the carotid artery, the largest vessel carrying blood to the brain.

"In contrast with endovascular treatment [angioplasty], surgical patients had about half the rate of strokes in long-term follow-up," said Dr. Martin M.

Ankle Circulation Could Warn of Future Strokes

August 28, 2009
Quick test may detect peripheral artery disease, research shows. A simple test of blood circulation in the ankle could help doctors identify patients at high risk of suffering another stroke, researchers say.

The test compares blood flow in the ankle to that in the arm. A significant difference between the two readings could suggest that a patient suffers from peripheral artery disease, caused by fatty plaque buildup in the arteries of the extremities, the researchers explained in a news release from the American Heart Association.

Newer, Better Tests for Heart Attacks

August 26, 2009
Troponin assays speed diagnosis, studies show. Two new European reports should help doctors decide which tests they choose to use for diagnosing possible heart attacks in emergency room patients, cardiologists say.

Both studies, which appear in the Aug. 27 issue of the New England Journal of Medicine, looked at tests for troponin, a protein released by damaged heart cells.

Tobacco Use Kills 6 Million People Annually

Report

August 25, 2009
And costs the global economy $500 billion each year. Tobacco use kills an estimated six million people worldwide each year and drains $500 billion annually from the global economy in lost productivity, misused resources, and premature deaths.

That assessment comes from The Tobacco Atlas, Third Edition, published by the American Cancer Society and the World Lung Foundation and released Tuesday at the LIVESTRONG Global Cancer Summit in Dublin, Ireland.

What's more, illnesses and deaths from tobacco use are totally preventable through such "well-established public policies" as tobacco taxes, advertising bans, smoke-free public places, and health warnings on packages, the report said.

Americans Are Urged to Cut Sugar Intake

August 24, 2009
Experts recommend far fewer teaspoons a day than average person now consumes. Most American women should not consume more than 100 calories of added sugar a day, while men should limit their intake to no more than 150 calories, according to a new recommendation from the American Heart Association.

"Added sugar" refers to sugars added to foods during processing, during cooking or when a food is consumed.

The recommendation works out to about six teaspoons of added sugar a day for women and about nine teaspoons for men.

Hypertension Linked to Thinking Problems in Middle Age

August 24, 2009
Increases in diastolic pressure lead to decreases in cognition, study shows. High blood pressure is linked to loss of mental function in people over 45, a new study finds.

"A number of other studies have looked at the relationship between blood pressure and cognitive function," said George Howard, chairman of the department of biostatistics at the University of Alabama at Birmingham School of Public Health, and a member of the team reporting the finding in the Aug. 25 issue of Neurology.

High-Octane Caffeine May Trigger Headaches

August 21, 2009
Heavy use linked to occasional headaches, small jolt tied to chronic head pain, study finds. Caffeine, known to help alleviate headaches, may cause them if consumed in large quantities.

That's the finding of a study of more than 50,483 people who were questioned about caffeine intake and headache frequency as part of the 1995-1997 Nord-Trondelag Health Survey (HUNT 2) in Norway.

The study was published recently in the Journal of Headache Pain.

Heart Risks Rise With Smokeless Tobacco

August 20, 2009
Increase is small but worth noting, expert says, as product use grows. Smokeless tobacco increases the risk of fatal heart attack and stroke, say researchers who reviewed the results of 11 studies conducted in North America and Sweden.

In recent decades, the researchers noted, the use of smokeless tobacco products has increased in Europe and North America, particularly among people younger than 40, partly because the products are promoted as safer alternatives to cigarettes.

However, their review found that users of smokeless tobacco products had a slightly higher risk of death from heart attack and stroke than non-users.

Blood Pressure Drug Might Work Against MS

August 17, 2009
Research shows inflammation link between two disorders. Dr. Lawrence Steinman has this seemingly crazy idea that a drug commonly used to combat high blood pressure can help prevent the damage done to nerve cells in multiple sclerosis.

But people in the know tend to listen carefully to the ideas of Steinman, a professor of neurology at Stanford University, because one of his ideas was crucial in the development of natalizumab (Tysabri), a now widely used medication that can reduce the incidence of relapses in multiple sclerosis (MS) by two-thirds.

Web Is Becoming One-Stop Shopping for Health Help

August 16, 2009
For support, advice or treatment, online interventions now await. People regularly turn to the Internet for games and gossip, news and entertainment, essential information and high weirdness.

And now, apparently, for their health as well.

A number of successful online medical interventions have been reported in recent months, helping folks quit smoking, lower their blood pressure and deal with any number of ailments.

Device May Offer Alternative to Warfarin for Arrhythmia

August 14, 2009
Implantation in people at risk for stroke could reduce medication use, study suggests. Closing the heart's left atrial appendage could offer an alternative to long-term warfarin treatment for people with non-valvular atrial fibrillation who are at risk for stroke, according to a new study.

Atrial fibrillation, the most common type of irregular heartbeat, causes the upper chambers of the heart to quiver. This can cause blood to pool and form clots in the left atrial appendage (LAA), a long, tubular structure connected to the left atrial cavity.

Aspirin May Stem Deaths From Colorectal Cancer

August 11, 2009
Study suggests a role for aspirin in prevention as well as treatment. Taking aspirin might not only reduce the risk of getting colorectal cancer, but it also might lower the odds of dying if you have it, new research suggests.

People with colorectal cancer who took aspirin regularly had a 29 percent lower risk for death from the cancer and a 21 percent lower risk for death from other causes, according to the research, reported in the Aug. 12 issue of the Journal of the American Medical Association.

How Weight Loss Helps the Heart

Study Ties Mini-Strokes to Memory Loss

August 10, 2009
Effects appear to differ from those of full-blown stroke. Screening for areas of damage from a possible mini-stroke could help predict memory loss in the elderly, say U.S. researchers.

In U.S., No Comeback Seen for Hormone Therapy

August 09, 2009
Experts say risks of long-term use still outweigh possible benefits. Hormone replacement therapy once seemed like a wonderful means to help women age gracefully. By dosing menopausal women with estrogen and progesterone as their bodies began to produce decreased amounts of those hormones, doctors believed they could help fend off heart disease, osteoporosis and cancer.

But those beliefs collapsed in 2002, when researchers pulled the plug three years early on the Women's Health Initiative, a large-scale, federally funded study of hormone replacement therapy (HRT).

Men With Angina Do Worse Than Women

August 06, 2009
Doubled rate of heart attack, tripled rate of death seen in study. New research shows that men diagnosed with the chest pain called angina did much worse than women, and neither artery-opening angioplasty nor coronary-bypass surgery reduced long-term mortality for either gender.

The study of 1,785 people newly diagnosed with angina at 40 primary-care practices in Scotland confirmed a previously reported difference between men and women that is something of a medical mystery, said Dr. Brian Buckley, a research fellow in the National University of Ireland department of general practice, and lead author of an Aug.

Combo Treatment May Ease Depression After Stroke

August 06, 2009
Therapy plus antidepressants improves mood and recovery, study finds. Adding psychosocial therapy to treatment with antidepressants helps improve depression and recovery in people who've had a stroke, a new study suggests.

"One-third of patients who have strokes develop clinical depression, which makes them less able to recover from the stroke, worsens cognitive functioning, impairs social functioning and is associated with other adverse consequences," study co-author Dr. Richard C.

Stroke Doubles Risk of Hip, Thigh Fractures

August 06, 2009
Preventive measures urgently needed, researcher says. The risk of a hip or thigh bone fracture is doubled for people who have a stroke, a new Dutch study finds.

That finding shows a need for immediate preventive action after a stroke, said Frank de Vries, an assistant professor of pharmacoepidemiology at the University of Utrecht, and lead author of a report that appears online Aug. 6 in the journal Stroke.

Young Vets With PTSD More Prone to Heart Risk Factors

August 04, 2009
Researcher suspects mental health issues may lead to unhealthy habits. Veterans of the Iraq and Afghanistan conflicts who have mental health problems such as post-traumatic stress disorder (PTSD) are also at higher risk for having cardiovascular disease risk factors, a new study suggests.

While previous studies have found that those with PTSD, a common mental health problem among veterans who have seen combat, are at increased risk of developing and dying from cardiovascular disease, risk factors for heart attack and stroke have not been evaluated in this group, said Dr. Beth E.

Induced Labor May Improve Outcome in Risky Pregnancies

August 04, 2009
Delivery at 37 weeks helps women with hypertensive disorders, study finds. Labor should be induced after 37 weeks in pregnant women with mild hypertension disorders such as high blood pressure and mild preeclampsia, according to a new study in The Lancet.

The study included 756 pregnant women in the Netherlands. All had been pregnant 36 to 41 weeks and had gestational hypertension or mild preeclampsia.

Young Kids' Screen Time May Raise Blood Pressure

August 03, 2009
Watching TV raises risk more than other low-level activities, such as painting, study finds. Young children who spend too much time in front of the television, the computer and video games might be at increased risk for high blood pressure, a new study suggests.

American and Spanish researchers examined the association between sedentary behavior and blood pressure in 111 boys and girls, 3 to 8 years old. For seven days, the children wore a special device that recorded their activity levels.

Calcium Scan of Arteries Helps Spot Big Trouble

July 29, 2009
Study shows it predicts severe events in those with known heart disease. Adding a scan for calcium in the heart arteries to a standard test of blood vessel function helps predict which people with known coronary disease are likely to develop serious problems, a new German study indicates.

"The combination of myocardial SPECT and coronary artery calcium scoring could help identify those who are at highest risk for subsequent fatal cardiac events in a long-term outcome," said study author Dr. Marcus Hacker, an associate professor of nuclear medicine at Ludwig Maximilians University in Munich.

More Dairy, Calcium in Childhood Could Mean Longer Life

July 28, 2009
Study beginning in 1930s suggests link, but experts unsure. A 65-year-long study finds that people who took in lots of calcium and dairy products as children tended to avoid stroke and live longer than those who didn't.

"This study shows a modest protective effect of dietary calcium intake in childhood against stroke risk later in life, and a modest protective effect against mortality from any cause from higher intake of milk in childhood," said Dr. David L.

Many Heart Attack Patients Not Referred to Cardiac Rehab

July 27, 2009
Despite benefits, only slightly more than half get it, study shows. Even though cardiac rehabilitation has been shown to guard against future heart trouble once a cardiovascular event has landed someone in the hospital, only 56 percent of these patients are referred for the therapy, a new study finds.

Despite national guidelines that say hospitalized patients with a qualifying cardiovascular disease event should be referred to outpatient cardiac rehabilitation before hospital discharge, the study demonstrates this doesn't happen often enough, the researchers noted.

"Cardiac rehabilitation improves clinical outcomes, but is widely underutilized," said researcher Dr.

People Over 60 at Risk for 'Silent Stroke'

July 27, 2009
High blood pressure and other factors play role, study says. People over the age of 60, especially those with high blood pressure, may experience a "silent stroke" and won't even know it, Australian researchers say.

"These strokes are not truly silent, because they have been linked to memory and thinking problems and are a possible cause of a type of dementia," study author Dr. Perminder Sachdev, a neuropsychiatry professor at the University of New South Wales in Sidney, said in a news release from the American Academy of Neurology.

New Anesthesia May Be Safer for Critically Ill

July 23, 2009
Lab tests of MOC-etomidate detected no sudden drops in blood pressure. A new variation of a common general anesthesia has been developed that may be safer for some patients.

Preclinical studies done on rats put under with MOC-etomidate, a chemically altered version of the anesthetic etomidate, found the drug does not cause blood pressure to drop suddenly or slow adrenal gland activity, common side effects that can be fatal to the elderly or certain critically ill patients.

"We have shown that making a version of etomidate that is broken down very quickly in the body reduces the duration of adrenal suppression while retaining etomidates benefit of keeping blood pressure much more stable than other anesthetics do," study leader Dr.

Attention Training Might Help Stroke Victims

July 23, 2009
Program to improve focus gets mixed results, but still looks promising, researchers say The inability to focus is a common problem for stroke survivors, and a new study finds they might benefit from attention-training.

New Zealand psychologists evaluated 78 stroke patients who underwent attention process training (APT) and found significant improvement on one test of attention compared to those who had standard stroke therapy, according to a report in the July 23 issue of Stroke.

But the improvement in attention was not accompanied by significant improvements in performance, and no differences were seen in three other tests of attention.

Carotid Artery Sections React Differently to Plaque

July 22, 2009
Findings may help explain location of deadly buildups One part of the carotid artery that supplies the brain with blood actually expands when deadly plaque builds up, but two other sections don't, and that can lead to a fatal stroke, researchers at Wake Forest University Baptist Medical Center have found.

MRIs revealed that the common segment shared by the right and left carotid arteries expands by 11 percent, on average, to keep blood flowing when complex plaque .

Five Hypertension Genes Found in Black Americans

July 17, 2009
Could be targets for new treatments, researchers say. Federal researchers have identified five genetic variants associated with high blood pressure in black Americans that could hopefully become targets for therapy to prevent and treat this major risk factor for heart disease and stroke.

Their study, reported in the July 17 online issue of PLoS Genetics, is one of a series being done to pinpoint possible genetic factors in high blood pressure and is the first to focus on blacks, said study senior author Charles Rotimi, a senior investigator at the National Human Genome Research Institute.

"Because of improvements in technology we are now able to look at variants in the entire human genome," said Rotimi, who is also director of the trans-NIH Center for Research on Genomics and Global Health.

Lower IQ Linked to Higher Risk of Heart Deaths

Blood Rush to the Brain When Angry Is a Good Sign

July 10, 2009
Healthy reaction to mental stress not seen in those with high blood pressure, study finds. Anger and other forms of mental stress cause dilation of the neck's carotid arteries and a rush of blood to the brain in healthy people, but this doesn't occur in those with high blood pressure.

That's the finding of U.S.

Study Pinpoints Risk Factors for Death in Young Stroke Victims

July 09, 2009
Many can be modified, treated to improve odds, experts say. Younger adults who suffer a stroke are more likely to die if they are heavy drinkers, have heart failure, cancer, type 1 diabetes or an infection before their stroke, Finnish researchers report.

Although the overall death rate in stroke patients aged 15 to 49 is low, four factors double the risk of death: heavy drinking; being 45 to 49; type 1 diabetes; or a having an infection beforehand. Moreover, having heart failure increased the risk of dying sevenfold and cancer increased the risk 16 times, the researchers found.

Mini-Strokes May Cause Vision Loss

July 07, 2009
Hong Kong researchers implicate silent infarcts in glaucoma. A study of people who suffer the mini-strokes called silent cerebral infarcts could help explain the medical mystery of normal-tension glaucoma, Hong Kong ophthalmologists report.

Glaucoma is the progressive loss of vision caused by deterioration of the optic nerves, which carry signals from the eyes to the brain. It is customarily attributed to abnormally high pressure of the fluid in the eye.

Drug Limits Stomach Trouble in Patients Taking Low-Dose Aspirin

July 06, 2009
Study found famotidine effective at curtailing ulcers. The drug famotidine prevents stomach and upper-intestinal ulcers in people taking low-dose aspirin, often to reduce the risk of heart attack, a new British study finds.

The phase III trial included 404 patients taking 75 milligrams to 325 milligrams of aspirin a day. They were randomly selected to take either 20 milligrams of famotidine or a placebo twice a day.

More Evidence That Caffeine Can Jolt Memory

Obesity Rates Continue to Climb in U.S.

July 01, 2009
Eight of 10 states with highest number of obese adults are in the South, report says. The rates of adult obesity in the United States increased in 23 states during the past year and did not decrease in any state.

And the number of obese and overweight children has now climbed to 30 percent in 30 states, a troubling trend that could signal decades of weight-related health problems such as cancer, diabetes and heart disease as these children become adults.

Those are just some of the worrisome findings in an annual report on obesity in America, released Wednesday by the Trust for America's Health and the Robert Wood Johnson Foundation.

Metabolic Syndrome May Make Breast Cancer More Likely

June 30, 2009
Study finds increased risk for postmenopausal women. Women with high blood pressure, elevated glucose and other components of metabolic syndrome might be at increased risk for postmenopausal breast cancer, a new study suggests.

Metabolic syndrome, also known as insulin resistance syndrome, consists of a cluster of such conditions as abdominal obesity, high blood glucose levels, impaired glucose tolerance, abnormal lipid levels and hypertension.

The study included 4,888 women, ages 50 to 79, who did not have diabetes at the start of the study and were periodically tested for components of metabolic syndrome over eight years as part of their participation in the Women's Health Initiative study.

Depression, Anxiety Bad for the Heart

Quick Angioplasty Best After Heart Attacks

June 24, 2009
Canadian study shows better survival when compared to those who got clot-busting treatment. A new Canadian study adds compelling support for current recommendations that people who first get clot-dissolving treatment for heart attacks should have artery-opening angioplasty as soon as possible afterward.

"This study strengthens the guideline recommendations," said Dr. Warren J.

Music Can Make the Heart Beat Faster

June 22, 2009
Or slower, with possible medical applications, research suggests. Loud music made hearts beat faster and blood pressure go up, while softer passages lowered both heart rates and blood pressure, a new study shows.

It's the latest word on how music affects the cardiovascular system, from researchers at Pavia University in Italy. Their earlier studies found that music with quicker tempos had people breathing faster, with increased heart rate and blood pressure, while slower tempos produced opposite effects.

Heart Attacks Less Often Fatal Today

June 21, 2009
Improved care and overall better health are credited with improved survival odds. People having a heart attack for the first time are more likely to survive these days than they would have decades ago, researchers have confirmed.

But now doctors are trying to puzzle out why heart attacks have become more survivable .

Painkillers May Be Good for the Prostate

June 21, 2009
Yet medical experts stress that men shouldn't take them with just this in mind. Taking over-the-counter painkillers such as aspirin and ibuprofen might help men avoid prostate problems.

But even so, medical experts are quick to caution men not to self-dose or to take more than the recommended amounts of these medications, because harmful side effects can result.

"Our data suggest if men are taking these [medications] for another problem, it might prevent urological problems as well," said Jennifer St.

Omega-3 Fatty Acids Might Curb Depression in Heart Patients

June 18, 2009
Study found low levels in bloodstream correlated with increased risk. New research suggests a relationship between low levels of omega-3 fatty acids and an increased risk of depression in heart patients.

The study, reported online in the Journal of Psychotherapy and Psychosomatics, looked at 987 adults with coronary heart disease. Among those with the lowest levels of omega-3 fatty acids, 23 percent suffered from depression.

Phone, Internet interventions can improve prognosis for cardiac disease, researchers say. Telephone or Internet-based interventions may help heart attack survivors and other cardiac patients improve their heart health and reduce their risk of future cardiac events, Australian researchers say.

They reviewed published randomized trials evaluating the use of phone- or Internet-based interventions in cardiac rehabilitation programs. Two of the interventions were Internet-based; all others were by telephone.

Stroke Damage Is Less in Rats Given Opioids

June 17, 2009
Drugs induce a state of hibernation that improves recovery, study shows. Hibernation induced by opioid drugs reduced brain damage and behavioral dysfunction in a study of rats that experienced an experimental stroke, researchers report.

"Studies in hibernating and active squirrels have shown that 'natural hibernation' has anti-ischemic effects," Cesar Borlongan, a neuroscientist at the University of South Florida Center for Aging and Brain Repair, said in a news release about the study. "We've shown that a drug that induces hibernation can achieve similar results.

New Anticoagulant Pill Works Well in Trial

June 17, 2009
Lower doses safe and effective after heart attack and stroke. The new anti-clotting pill rivaroxaban (Xarelto) lowers the risk of stroke, heart attack and death in patients who have had a heart attack or suffer from unstable angina, a new trial shows.

Rivaroxaban is a pill that blocks factor Xa, which is involved in blood clotting. In earlier studies, the drug was effective in preventing venous thromboembolism (blood clots in the legs) after orthopedic surgery, although some increased risk in bleeding episodes was seen.

Lifestyle May Counter Blood Pressure Genes

June 16, 2009
Smoking, drinking and more can override what you're born with, study finds.Being born with genes that predispose you to high blood pressure doesn't mean you're doomed to have it, a long-term study shows.

"It's been known for many years that blood pressure is affected by genes," said Dr. Nora Franceschini, an assistant professor of epidemiology at the University of North Carolina and lead author of a report on the study.

Psoriasis Raises Risk of Heart Attack, Stroke, Death

June 15, 2009
Inflammation looks like common thread, researcher says. People with psoriasis face an increased risk of major cardiovascular disease and death, a new study finds.

The research, which included data from a Veterans Administration medical facility study to compare 3,236 people suffering from the skin disease to 2,500 psoriasis-free individuals, found a 78 percent higher incidence of heart disease, a 70 percent higher incidence of stroke and a 98 percent higher incidence of peripheral arterial disease (blockage of arteries in the legs) in the psoriasis group.

The overall death rate for those with psoriasis was 86 percent higher than for those without the disease.

Lack of Sleep Can Raise Blood Pressure Over Time

June 08, 2009
Risk increased as sleep duration decreased, researchers found. Middle-aged adults who don't get enough sleep are at increased risk of developing high blood pressure, a new study has found.

Over the course of five years, Kristen L. Knutson of the University of Chicago and colleagues collected health information, such as blood pressure readings, and measured the sleep duration of 578 adults with an average age of 40.

Fewer Deaths Occurring From Brain Bleeds

June 04, 2009
Better diagnosis, treatments behind decrease, researchers say. Better diagnosis and treatment have led to fewer deaths from the rupture of a blood vessel on the surface of the brain, Dutch researchers say.

Known as a subarachnoid hemorrhage, this kind of rupture leads to bleeding into the space between the brain and the thin tissue that covers the brain. It can occur spontaneously, usually from a weakness in a blood vessel or a head injury.

Pay-for-Performance Doesn't Shortchange Patients

June 03, 2009
VA study found those with complicated conditions still received high-quality care. A new study on pay-for-performance medical care should reassure patients and the doctors who treat them.

"On the patient side, there is concern that patients whose condition is complex may not get the high-quality care that they need," explained study author Dr. Laura Peterson.

Weight-Loss Surgery Options Compared in Super-Obese

June 02, 2009
Duodenal switch may be more effective than gastric bypass, researchers say. A technique called duodenal switch surgery may be more effective than gastric bypass surgery for patients with obesity-related medical problems such as high cholesterol, diabetes and high blood pressure, according to a U.S. study that included 350 super-obese patients who were more than 200 pounds heavier than their ideal body weight.

Research Finds 'New Crop' of Breast Cancer Genes

June 01, 2009
Study in mice also suggests possible treatment with blood pressure med. Researchers say they have found a gene common in up to one in five breast cancers that a blood pressure medication might combat.

Their study, published online in this week's issue of the Proceedings of the National Academy of Science, found that the AGTR1 gene makes healthy breast cells act like cancer cells. But tests on mice with tumors containing the gene found that the blood pressure drug losartan (Cozaar) stopped that behavior and shrank the tumors by 30 percent within eight weeks of treatment, according to the researchers, from the University of Michigan Comprehensive Cancer Center.

Mini-Stroke Can Mean Major One Within Hours

June 01, 2009
If full-blown stroke occurs, it often comes within a day, study shows. About half the people who have a major stroke soon after a less serious brain event, such as a transient ischemic attack or "mini-stroke," do so within 24 hours of the minor event, a new study finds.

The message here for people who have a TIA is to "seek medical attention immediately, particularly if you have either weakness or speech disturbance that lasts more than 10 minutes," said the study's senior author, Dr. Peter M.

Laughter Can Boost Heart Health

May 29, 2009
Research finds it improves blood flow and may help ward off high blood pressure. New research lends weight to the old adage that laughter can be powerful medicine, particularly when it comes to your heart.

Two studies presented at the American College of Sports Medicine's annual meeting in Seattle found that laughter not only can reduce stress, which can damage the heart, it can lead to improved blood flow, which can help ward off high blood pressure.

The first study included a small group of healthy adults who were asked to watch either a comedy or documentary film.

Value of Taking Aspirin to Cut Heart Risk Varies

May 29, 2009
For those with no history of heart disease, risks may outweigh benefits, research suggests.Taking aspirin reduces heart attack risk in people with no previous history of vascular disease but increases the risk of internal bleeding, say British researchers who analyzed the results of 22 clinical trials.

This means the net effect in this group of patients is uncertain because the benefits and risks may cancel each other out. However, the researchers found that aspirin's benefits generally outweigh its risks among people who have vascular disease.

Stimulant Chewing Gum Can Be Dangerous for Kids

May 29, 2009
Case report details how two packs sent 13-year-old to hospital. Stimulant chewing gum can be dangerous if used excessively by children and teens, warn doctors who wrote a case report about a teenage boy who was hospitalized after chewing a large amount of the caffeine-containing gum.

The case involved a 13-year-old Italian boy who was taken to hospital after his family noted he was agitated and aggressive, which wasn't typical for him. The boy also had abdominal discomfort, increased and painful urination, and prickling sensations in his legs.

Window for Stroke Treatment Opens Wider

May 28, 2009
Clot-busting drug found effective 4.5 hours after symptoms begin. A new analysis showing that a potent clot-dissolving drug can safely be used to treat strokes four-and-a-half hours after symptoms begin has prompted a change in a current recommendation, which set a three-hour deadline for the medication's use.

The review of 1,622 cases of people treated with tissue plasminogen activator (tPA) in four separate studies finds that the benefit in keeping brain cells alive outweighs the risk of brain-damaging bleeding when the drug is given up to 4.5 hours after first symptoms, according to a report in the May 28 online issue of Stroke.

Tactile input plays a key role in visualization, study finds. Touch alone can activate areas of the brain triggered when people look at objects, a finding that shows that these regions process information about objects using different types of sensory input, according to a new study.

Researchers at the University of Birmingham in the United Kingdom studied a man who suffered stroke-related damage in an area of the brain called the lateral occipital cortex (LO), which plays an important role in object recognition. As a result, the man couldn't process visual input normally; he could see objects, but they were jumbled figures to him a condition called visual agnosia.

Compression Stockings Offer Little Benefit After Stroke

May 28, 2009
Risk of blood clots not affected by their use, new research shows. Compression stockings don't reduce the risk of blood clots in stroke patients, according to a study that urges revision of guidelines on the use of the support hose.

The study included 2,518 immobile patients in Europe and Australia who were admitted to hospital within one week of experiencing an acute stroke. Some patients received routine care plus thigh-length graduated compression stockings, while other received routine care only.

Hardened Arteries Threaten Obese, Diabetic Youth

May 26, 2009
Ultrasound shows damage tied to rising odds for stroke, heart attack, researchers say. An examination of the neck arteries of today's obese or diabetic young people bodes ill for their future health, researchers report.

The walls of these carotid arteries, which carry blood to the brain, showed a thickening and stiffness known to increase the risk of future strokes, heart attacks and other cardiovascular problems, according to a report to be published in the June 9 issue of Circulation.

"Since the 1980s, there has been a major increase in obesity in our youth," said Dr.

Gum Disease, Heart Disease Share Genetic Link

May 26, 2009
Discovery helps explain association between the two illnesses. A genetic link between gum disease (periodontitis) and heart disease has been discovered by German scientists.

The association between periodontitis and coronary heart disease (CHD) has been known for years, but a genetic link between the conditions hadn't been confirmed. The University of Kiel team found that the two diseases share a genetic variant on chromosome 9.

Statins Can Help Prevent Second Stroke

May 26, 2009
New study strengthens prior research on the cholesterol-lowering drugs. Taking a cholesterol-lowering statin after a stroke reduces the risk of a second stroke, new research shows.

The 10-year study of nearly 800 people who had strokes found a 35 percent lower incidence of second strokes and a 57 percent lower death rate among those who took statins compared to those who didn't, according to a report in the May 26 issue of Neurology.

Statins include blockbuster medications such as Crestor, Lipitor, Pravachol and Zocor.

When Chest Pain Requires Quick Action in ER

May 20, 2009
Urgency needed in only one-third of cases, study says. Only one-third of the people who come to a hospital with the intense chest pain that doctors call acute coronary syndrome should be assessed for artery-opening procedures within a few hours, a new Canadian study finds.

The rest are at lower risk for a heart attack and won't be harmed by waiting a day or two, the researchers added.

There is often an issue about whether such assessment and treatment is needed quickly, said Dr.

Drug Combo Keeps Kidney Artery-Vein Grafts Viable

May 20, 2009
Aspirin plus anti-clotting therapy boosts dialysis patients' quality of life, study says. A combination of aspirin and the anti-clotting drug dipyridamole reduces blockages and extends the useful life of new artery-vein access grafts used for kidney dialysis, new research has found.

When arteriovenous (AV) grafts fail, it is often due to stenosis .

Stem Cells May Offer New Way to Treat Blocked Arteries

May 19, 2009
Injections into heart restore blood flow in small study. Injecting bone marrow cells into the heart's muscular wall restored blood flow to hearts with blocked arteries for which conventional treatments had proven ineffective, Dutch physicians have reported.

"I think this is very good news for patients who are at the end of the line and have no options left," said Dr. Douwe E.

Years of Heavy Smoking Raises Heart Risks

May 15, 2009
30-year study in Norway sheds light on 'tremendously adverse' effects of tobacco use. Highlighting the negative impact tobacco use has on cardiovascular health, researchers say that heavy smokers were 2.5 times more likely to die than their non-smoking peers during a 30-year study in Norway.

The newly available research found that nonsmokers lived longer and experienced fewer incidents of heart attack and cardiovascular disease than smokers, especially when compared with heavy smokers (those who lit up at least 20 cigarettes a day).

Chewable Aspirin More Readily Absorbed

May 15, 2009
Study suggests higher levels found in bloodstream could improve heart attack treatments. Chewable aspirin is more readily absorbed into the bloodstream, making it the best aspirin choice for people suffering a cardiac incident, University of California, San Diego researchers report.

Volunteers who consumed chewable aspirin had higher levels of aspirin in their blood shortly afterward when compared with people who either swallowed regular aspirin whole or chewed then swallowed regular aspirin, according to the study, scheduled to be presented Friday at the Society for Academic Emergency Medicine's annual meeting in New Orleans.

Doctors sometimes prescribe aspirin to people who have had a cardiac incident or are at high risk for one.

Viral Infection Might Trigger High Blood Pressure

May 15, 2009
Mouse study shows CMV raises risk of hypertension, hardening of arteries. A hidden viral infection that most adults harbor could be a cause of high blood pressure, animal studies indicate.

Mice infected with cytomegalovirus (CMV) were more likely to develop not only high blood pressure but also the hardening of the arteries called atherosclerosis, according to a report in the May 15 issue of PLoS Pathogens by researchers at Beth Israel Deaconess Hospital in Boston.

"This could be of immense importance," said lead researcher Dr.

'Stun Gun' Deaths Rarely Caused by Ventricular Fibrillation

May 14, 2009
Other heart irregularities more likely to blame, study says.News media periodically report on people dying after being shocked by Tasers, better known as "stun guns."

But instead of immediately dropping to the ground, people often take as long as 13 minutes to collapse, new research shows.

And though the cause of death is often attributed to ventricular defibrillation, an often fatal heart arrhythmia believed to be caused by the electrical stimulation, other types of heart arrhythmias are a more common cause of death.

Psychiatric Drugs Might Raise Cardiac Death Risk

May 14, 2009
But other medical factors could also be at play, researchers note. Preliminary research suggests people who suffered fatal cardiac arrest were more likely to have taken antidepressants and other psychiatric drugs than those who survived heart attacks.

But the findings haven't been confirmed elsewhere, and it's not clear whether the medications directly cause any problems. Those who take the drugs could have other medical issues that contribute to a higher death rate, the researchers noted.

Subway Defibrillators Save Lives

May 14, 2009
Publicly accessible devices prevent heart-attack deaths, study finds.The use of automated external defibrillators (AEDs) in public places such as subways can save lives, new research from Germany shows.

A study of AEDs installed in Munich subways found they saved the lives of 12 people suffering heart attacks since the AEDs' installation in 2001. The defibrillators are increasingly common in public facilities, office buildings and transit stations across the United States and Europe.

Risk Factor for Stroke More Common Among Whites

May 14, 2009
Despite risk factors, blacks less likely to suffer atrial fibrillation. Whites are more likely than blacks to experience atrial fibrillation, a cause of stroke, even though blacks have a higher prevalence of risk factors such as high blood pressure, new research shows.

About 2.2 million Americans have atrial fibrillation, a heart arrhythmia in which the two upper chambers, or atria, quiver chaotically instead of beating in a normal rhythmic pattern, according to the Heart Rhythm Society.

Aspirin Lowers Stroke Risk in Peripheral Artery Disease

May 12, 2009
But findings limited by lack of studies on subject, researchers note. There haven't been enough studies to tell whether aspirin reduces the risk of heart attack and death for people with the blocked leg blood vessel condition called peripheral arterial disease, but it does cut the incidence of stroke, researchers report.

The finding comes from a meta-analysis of the not-too-many studies of aspirin use with peripheral arterial disease (PAD); it appears in the May 13 issue of the Journal of the American Medical Association.

It's not clear why PAD has been a neglected subject, said study co-author Dr.

Seniors Often Misstate Stroke History

May 11, 2009
Study suggests MRI scans better than questionnaires for evaluations. Many seniors who've had a stroke fail to report that fact, say researchers who recommend the use of MRI scans rather than patient self-reporting to determine stroke history.

The study included 717 Medicare recipients aged 65 years and older (average age 80.1) in Manhattan.

Not All Caregivers Are Stressed and Depressed

May 08, 2009
Some discover satisfaction in challenging role, survey finds. Though caring for a stroke survivor can be challenging, many family members doing just that say they experience little or no stress and actually find the task personally rewarding, U.S. researchers have found.

After Job Loss, People Report More Health Issues

May 08, 2009
Society should consider ways to mitigate the effects, experts say. Losing a job can lead not just to financial hardships but to health problems as well, including high blood pressure, diabetes, heart disease, heart attack and stroke, new research has found.

"In today's economy, job loss can happen to anybody," Kate Strully, who conducted the research as a Robert Wood Johnson Foundation scholar at the Harvard School of Public Health, said in a news release from the foundation. "We need to be aware of the health consequences of losing our jobs and do what we can to alleviate the negative effects.

Too-Low Blood Pressure Can Also Bring Danger

May 07, 2009
What's OK for the kidney and brain may not be best for the heart, expert says. While too-high blood pressure is a clear hazard for most people, too-low pressure can apparently be a threat in some cases as well.

A new study of 10,001 people with coronary artery disease found what statisticians call a J-shaped curve of mortality, meaning a higher death rate for people with the lowest blood pressure. Dr.

Consider TIAs an Emergency, Groups Urge

May 07, 2009
Experts say risk of full-blown stroke is higher than once thought."Mini-strokes" should be treated with the same urgency as a full-blown stroke, urges the American Heart Association/American Stroke Association.

That's because the risk of a major stroke after a warning stroke, known as a transient ischemic attacks (TIA), is higher than previously thought, according to a scientific statement from the groups released Thursday.

"We think a TIA should be treated as an emergency, just like a major stroke," Dr.

Telemedicine Helps Experts Treat Stroke From Afar

May 07, 2009
AHA recommendations aim to improve care in underserved patients. Examining stroke patients via videoconferencing (telemedicine) is as effective as a bedside exam and can increase patient access to stroke specialists, says a scientific statement released Thursday by the American Heart Association.

Stroke patients require rapid assessment in order to determine if they're eligible for time-sensitive treatments such as tissue plasminogen activator (tPA), which can save brain function and reduce stroke-related disability, the AHA explained in a news release.

These patient evaluations often need to be done by stroke and brain imaging specialists, but there are only about four neurologists per 100,000 people in the United States, and not all neurologists specialize in stroke, according to the statement.

All Blood Pressure Drugs Lower Risk of Heart Attack and Stroke

May 07, 2009
Any are better than no treatment at all, study shows.Lowering blood pressure is essential for reducing the risk of heart disease and stroke, but which drugs are best has been a matter of debate.

Now, two new analyses attempt to answer that question.

Their conclusions: For heart attacks, all antihypertensive drugs work, with the exception of angiotensin receptor blockers (ARBs), probably because there aren't enough studies to confirm their benefit.

Plavix, Heartburn Drugs May Be Risky Combination

May 06, 2009
Patients with stents should discuss the use of these meds with their doctor, cardiac group says. Anyone who takes the clot-preventing drug Plavix after receiving a stent in a coronary artery-opening procedure should avoid popular heartburn medications called proton pump inhibitors (PPIs), if possible, a group of heart experts now say.

PPIs include blockbuster acid reflux medications such as Nexium, Prevacid and Prilosec.

The problem, according to experts at the Society for Cardiovascular Angiography and Interventions (SCAI), is that the combination of Plavix and a PPI increases the user's risk of heart attack, stroke and other cardiovascular problems.

Urine Test Predicts Vein Clot Risk

May 05, 2009
Those with elevated albumin levels were more likely to get DVT, pulmonary embolisms. A higher-than-normal level of the protein albumin in urine indicates an increased risk of dangerous blood clots in the deep veins of the lungs and legs, a Dutch study finds.

These venous thromboembolisms (VTEs) include deep vein thrombosis (DVT), a clotting in the lower extremities which gained recent notoriety when it occurred in passengers on long-haul flights. These clots can become dangerous if they travel to the lungs to produce a pulmonary embolism.

Phone Monitoring May Help Lower Blood Pressure

May 05, 2009
Weekly contact via automated system proves beneficial in study. An automated calling system helps people with hypertension be more aware of the potentially disabling or fatal consequences of their condition and helps them reduce their blood pressure, new research has found.

The study included 223 people at eight primary care clinics near Montreal. They all wore portable monitors that took 24-hour blood pressure readings.

Telling Heartburn From Heart Attack Can Be Tricky

May 05, 2009
Because of similar symptoms, doctors urge overreaction if in doubt. It begins as a sharp, burning sensation in the chest, near the breastbone or ribs. But is the pain heartburn, or might it be a heart attack?

"It's often difficult for people to tell the difference,'' said Dr. Ravi Dave, a cardiologist and associate clinical professor of medicine at the David Geffen School of Medicine at the University of California, Los Angeles.

Black Youths With High BP May Face Elevated Heart Risks

May 03, 2009
They also had raised cholesterol, so study suggests better screening for hypertension. While untreated hypertension in any child could lead them to developing a potentially dangerous enlargement or thickening of one chamber of the heart, a new study suggests that black children may be at a greater risk than all other racial groups.

While studying 139 high blood pressure patients under age 21, researchers from Johns Hopkins Children's Center found that about 60 percent of those who were black had left ventricular hypertrophy (LVH), a condition that can cause heart failure, problems with heart rhythm and death. The researchers found LVH in just 37 percent of the other children.

Managing Blood Pressure, Cholesterol Cuts Stroke Risk

April 30, 2009
Study shows reaching optimal levels protects against heart attack, too People who have suffered a stroke can significantly reduce the odds of a second stroke or a heart attack by controlling their blood pressure and cholesterol, new research shows.

"There are about 800,000 new strokes in the U.S.

Urine Test for Heart Disease Shows Promise

April 29, 2009
Noninvasive method detects dangerous levels of artery-blocking proteins. A urine test to detect coronary artery disease has worked well in a small trial, German researchers report.

The test looks for fragments of the protein collagen, which plays a major role in blocking heart arteries, said study author Dr. Constantin von zur Muehlen, a fellow in cardiology at University Hospital Freiberg.

Smoking, Hypertension Each Account for 1 in 5 U.S. Deaths

April 28, 2009
Prevention efforts 'have run out of steam,' expert says. Want to reduce your risk of dying prematurely? Don't smoke and keep a healthy blood pressure level.

Each of those factors accounts for about one in five deaths among U.S.

With Peripheral Artery Disease, Med Adherence Is Low

April 24, 2009
Survival, though, is greater when guidelines are followed, study finds. Less than half of those who have peripheral artery disease are taking the recommended combination of medications to control it, new research says.

Researchers collected data on 711 people with peripheral artery disease who had vascular surgery at 11 hospitals in the Netherlands in 2004. Three years later, 465 of the surviving 552 patients answered a questionnaire about their medication use.

Coordination Has Led to Quicker Heart Treatment

April 24, 2009
Experts urge establishment of more regional networks. Better coordination between paramedics, emergency room staff and laboratory personnel has led to steady improvements in the time needed to restore blood flow to people having a severe heart attack, new research shows.

The study involved patients who had what's known as an ST elevation myocardial infarction (STEMI), the deadliest type of heart attack. They were treated initially at a major North Carolina medical center or transferred there from other area hospitals.

Reduce Suffering, Urge Heart Failure Patients and Caregivers

April 24, 2009
Survey finds that psychological needs are going unmet. People with heart failure, and those who care for them, want more attention paid to their psychological needs, a new study finds.

"Heart failure patients and their caretakers suffer in a variety of ways," said Dr. David Bekelman, an assistant professor of medicine at the University of Colorado Health Sciences Center, who was to present the study Friday at an American Heart Association meeting in Washington, D.

Limited English May Be Life-Threatening

April 24, 2009
Study finds lower survival among less-fluent heart attack victims. Having limited knowledge of English can be dangerous for people having a heart attack, new research shows.

People who have limited English proficiency were less likely to have a bystander come to their aid with CPR, faced a greater delay in receiving CPR because dispatchers took longer to recognize the need, and were less likely to survive.

The findings stem from an analysis of data on 906 confirmed cases of cardiac arrest, or the abrupt stoppage of the heart, that occurred away from hospital settings in Kings County, Wash.

Lowered HRT Use May Have Cut Heart Attacks

April 24, 2009
But women didn't experience a similar drop in strokes, study finds. The decline in the use of hormone replacement therapy (HRT) to treat menopause symptoms has been mirrored by a drop in the rate of heart attacks among American women, a new study finds.

But there's been no decrease in the rate of strokes, researchers noted.

Hormone replacement therapy was widely used to treat menopause symptoms until 2002, when researchers published a study that said HRT increased the risk of heart attack.

Work Strife Stresses the Heart

April 24, 2009
The link seems certain but solutions less so, experts say. In tough economic times, work stress might be hard to avoid. But for people in stressful jobs, it's especially important to take steps to manage the stress in order to protect the heart.

That's because stress not only has been shown to increase the risk of a first heart attack, but also a second.

Fatty Fish May Cut Heart Failure Risk in Men

April 22, 2009
Study finds benefit from consuming just one serving a week. Men who consume fatty fish and marine omega-3 fatty acids appear to have a reduced risk of heart failure, a new study has found.

Between 1998 and 2004, U.S.

Health Tip

Signs That You've Had Too Much Caffeine

April 21, 2009
Should you be drinking less coffee, tea or soda? You may relish that first cup of coffee in the morning, then a few more cups throughout the day. But if you've had too much caffeine, which is a stimulant, it can lead to significant side effects.

The National Sleep Foundation offers these symptoms of excessive caffeine consumption:



A decline in fine motor coordination.

Fructose-Sweetened Drinks Up Metabolic Syndrome Risk

April 20, 2009
But glucose-based beverages may not have same impact, study finds. Fructose-sweetened soft drinks and other beverages can have a negative effect on the body's sensitivity to insulin and its ability to handle fats, increasing the risk of heart attack and stroke, a new study suggests.

But glucose-sweetened beverages don't have that kind of impact, the study found.

The research included overweight and obese volunteers who for 10 weeks drank either fructose- or glucose-sweetened beverages that supplied 25 percent of their energy needs.

'Silent' Heart Attacks More Common Than Thought

April 20, 2009
Since they leave few signs, imaging reveals patients at much greater risk for death. "Silent" heart attacks occur more often than previously believed and are associated with a high risk of premature death, according to a Duke University Medical Center study.

These silent heart attacks, also called non-Q-wave unrecognized myocardial infarctions (UMIs), often go undetected because they don't cause any pain and don't leave behind telltale irregularities that can be detected on electrocardiograms (EKGs).

"No one has fully understood how often these heart attacks occur and what they mean in terms of prognosis.

Having Psoriasis Raises Risk of Diabetes, Hypertension

April 20, 2009
Researchers suspect chronic inflammation is common thread among all 3 conditions. A new study lends more credence to a long-suspected connection between psoriasis, diabetes and hypertension.

Researchers reporting in the April issue of the Archives of Dermatology suspect the link may have to do with the chronic inflammation that is associated with all three conditions.

"We were able to prospectively evaluate the risk of diabetes and hypertension in U.

Secondhand Smoke Quickly Affects Blood Vessels

April 17, 2009
As little as 10 minutes of exposure changes cardiovascular function, researchers say. Cardiovascular function can be affected by as little as 10 minutes exposure to secondhand cigarette smoke and other air pollutants such as wood smoke and smoke from cooking oil, say U.S. researchers.

A Blood Pressure Monitor to Wear on Your Wrist

April 16, 2009
MIT researchers design lightweight sensor that can take readings at will. Imagine being able to check your blood pressure with a quick glance at your wrist.

Engineers at the Massachusetts Institute of Technology (MIT) have produced a prototype of such a device, which they hope will overcome the limitations of current blood pressure-monitoring systems.

"A wearable blood pressure monitor can get data regularly," said H.

Halting Avandia Use Hikes Blood Sugar Levels

April 16, 2009
Study found diabetics who discontinued drug had less treatment, worse management of disease. Many patients who stopped using the diabetes drug rosiglitazone (Avandia) due to concerns about the drug's safety received less treatment and developed higher blood glucose levels, U.S. researchers report.

Scientists Spot Stroke Genes

April 15, 2009
Chromosomal region contains two suspect variants that raise risk for brain attack. Scientists have identified a chromosomal region that may contain two genetic variants responsible for an increased risk of ischemic stroke.

About 20 percent of whites and 10 percent of blacks in the United States and Europe have at least one copy of the genetic variant. Each variant increases the risk of this type of stroke by 30 percent, according to the authors of a study being published online Wednesday and in the April 23 print issue of the New England Journal of Medicine.

Blood Pressure Drug May Not Ease Irregular Heartbeat

April 15, 2009
Despite earlier promise, valsartan fails to deliver against atrial fibrillation, researchers say. The blood pressure drug valsartan may not prevent episodes of a dangerous abnormal heart rhythm called atrial fibrillation, an Italian study finds.

Earlier research had suggested that valsartan (Diovan) might reduce the occurrence of atrial fibrillation, a faulty heartbeat that can lead to the formation of clots that can cause heart attack or stroke.

"But in the patients we randomized in this study, it was not useful in preventing recurrence," said study author Dr.

Acetaminophen, Cholesterol Drugs May Help Fight Stroke

April 15, 2009
Statins could help prevent attack, while painkiller might minimize damage, studies find. Two new studies find that acetaminophen and statins can be of great benefit in either preventing or treating stroke.

In the first study, statin use seemed to be correlated with a lower risk of having a first stroke, according to a group of French researchers.

Meanwhile, another team in the Netherlands found that patients with a body temperature ranging from normal (98.

Former Inmates at Increased Risk for High Blood Pressure

April 14, 2009
And they're more likely to lack treatment for it years after freedom, study finds. Young adults who are former prison inmates are at increased risk for high blood pressure and a related heart condition called left ventricular hypertrophy, a U.S. study finds.

Heart Disease and Depression Up Heart Failure Risk

April 13, 2009
Use of antidepressants makes little difference, study finds. Depression increases the risk that people with heart disease caused by blockage of coronary arteries will develop heart failure, a new study finds.

That finding was to be expected, said Heidi May, an epidemiologist at the Intermountain Medical Center in Murray, Utah, and lead author of the study, because earlier research had found that depression increases the risk of heart failure in otherwise healthy people. Heart failure is a progressive loss of the ability to pump blood.

Review Confirms Links Between Diet, Heart Health

April 13, 2009
Vegetables, nuts, and 'Mediterranean' fare most beneficial, researchers find. Vegetables, nuts and the so-called "Mediterranean" diet are heart-friendly, while trans fats and foods with a high glycemic index can harm your heart, say researchers who reviewed 189 studies published between 1950 and 2007.

The studies included 146 prospective cohort studies (which examined past habits of participants) and 43 randomized controlled trials (volunteers were randomly assigned to consume a certain kind of diet).

"The relationship between dietary factors and coronary heart disease has been a major focus of health research for almost half a century," wrote Andrew Mente, of the Population Health Research Institute, and colleagues.

Aspirin Linked to Brain Microbleeds

April 13, 2009
Significance unclear, expert says. A Dutch study finds an increased incidence of tiny bleeding episodes in the brains of people who regularly take aspirin.

Magnetic resonance imaging (MRI) examinations of 1,062 people found a 70 percent higher incidence of "microbleeds" among those taking aspirin or carbasalate calcium, a close chemical relative of aspirin, than among those not taking such anti-clotting drugs, according to an April 13 online report in the Archives of Neurology from physicians at Erasmus MC University Medical Center in Rotterdam. The research was expected to be published in the June print issue of the journal.

Screening Lowers Stroke Risk for Sickle Cell Kids

April 13, 2009
But access to the tests is limited for children living far from centers, experts say. A specialized ultrasound scan is helping more children with sickle cell disease avoid strokes, but that good news is tempered by the limited access most children with the disease have to labs offering this screening, a new report notes.

People with sickle cell disease, an incurable disorder of the red blood cells, run an increased risk of stroke. About 10 percent of children with the disease have a stroke before turning 21.

Exercise Might Benefit Some With Heart Failure

April 07, 2009
Improvement was modest, but activity is safe and should be urged, expert says. A regular program of moderate exercise will not harm people with heart failure and probably will benefit some of them, a new study has found.

That admittedly tepid conclusion comes from a major government-funded trial that enrolled 2,331 people with heart failure at 82 centers in the United States, Canada and France.

Some were started on a 36-session training program and advised to have regular sessions of aerobic-type exercise, such as walking on a treadmill for 25 or 30 minutes, five times a week.

Trouble Sleeping? Try These Tips

April 03, 2009
What you do and drink before bedtime can have an effect. Though the value of a good night's sleep is well known, it's not uncommon for people to get far less than the eight hours recommended for peak performance.

The Comprehensive Epilepsy and Sleep Disorders Center at Baylor Regional Medical Center in Texas offers these explanations why, and tips on how to get more shut-eye:

Control caffeine. The cycle of downing a large cup of coffee to wake up in the morning and more after dinner, whether out of habit or desire to stay up late, counters the body's ability to sleep soundly on its own.

Daily Naps May Raise Older Women's Death Risk

April 02, 2009
Addressing where the drowsiness comes from may be the solution, researchers say. A daily nap may boost an elderly woman's risk of dying, a new study suggests.

In contradiction of numerous past studies that have found that napping may have health benefits, researchers from the California Pacific Medical Center Research Institute found that elderly white women who took a daily siesta were 44 percent more likely to die from any cause, 58 percent more prone to dying from heart problems, and nearly 60 percent more likely to die from non-cardiovascular or non-cancer causes.

The results .

Atkins Diet Tougher on Heart After Weight Loss

April 01, 2009
Study found worse cholesterol, blood vessel health than with South Beach, Ornish regimens. In the "maintenance" phase that occurs after initial weight loss, the popular Ornish and South Beach diets seem to be easier on the heart than the high-fat, low-carbohydrate Atkins regimen, a new study finds.

Unlike numerous studies that have evaluated diets to see which might be better at achieving weight loss, this study, funded by the U.S.

Stem Cell Injections Seem to Reduce Angina Pain

March 30, 2009
Early study finds improved ability to exercise within 6 months. In people with severe angina, injecting their own stem cells into the heart muscle appears to reduce pain and improve their ability to exercise, say U.S. researchers.

Omega-3s of No Added Benefit to Heart Attack Patients

March 30, 2009
Standard therapy wipes out any protection the supplement might provide, study finds. Patients receiving optimal drug therapy after suffering a heart attack do not gain any additional benefit from taking supplemental omega-3 fatty acids, a new study finds.

In a study of almost 4,000 people who suffered heart attacks, researchers found no difference in rates of heart attack, stroke, sudden cardiac death or death from any cause regardless of whether they were taking the supplements or not. This finding contradicts previous studies, which suggested that taking omega-3 fatty acids improved long-term survival.

Statin Might Help Fight Blood Clots in Veins

March 30, 2009
Cholesterol-lowering Crestor cut risk by 43%, study found. In addition to dramatically reducing the incidence of heart attacks and stroke, the cholesterol-lowering drug Crestor appears to have another important benefit: reducing the rate of blood clots in the veins, new research has found.

Interestingly, participants in this study, which was presented Sunday at the American College of Cardiology annual meeting, in Orlando, Fla., did not have elevated levels of LDL, or "bad," cholesterol, but they did have increased levels of the inflammatory marker called C-reactive protein (CRP).

Kidney Nerve Deactivation Could Ease Hypertension

Statin Might Help Fight Blood Clots in Veins

March 29, 2009
Cholesterol-lowering Crestor cut risk by 43 percent, study found. In addition to dramatically reducing the incidence of heart attacks and stroke, the cholesterol-lowering drug Crestor appears to have another important benefit: reducing the rate of blood clots in the veins, new research has found.

Interestingly, participants in this study, being presented Sunday at the American College of Cardiology annual meeting in Orlando, Fla., did not have elevated levels of LDL, or "bad," cholesterol, but they did have increased levels of the inflammatory marker called C-reactive protein (CRP).

Super Bowl Loss Can 'Kill' Some Fans

March 30, 2009
Study found death rates rose after a defeat, and dropped after a victory Watching your favorite NFL team lose in the Super Bowl could actually end your life, a new study suggests.

However, the good news is that a victory might do just the opposite, the researchers noted. The finding was presented Saturday at the American College of Cardiology annual meeting, in Orlando, Fla.

New Device Treats Common Heart Rhythm Disorder

March 30, 2009
It could replace anti-clotting drug warfarin for many patients, researchers say. An implanted device may soon replace the anti-clotting drug warfarin as the first line of treatment for many people with atrial fibrillation, a new study suggests.

People with atrial fibrillation have a sixfold increased risk of stroke, the researchers noted, and typically need to take warfarin for the rest of their lives. Atrial fibrillation is a common heart rhythm problem that causes the upper chamber of the heart to beat irregularly.

Kidney Ailments May Rise Along With Blood Pressure

March 27, 2009
Findings emphasize value of early screening programs, report concludes. The higher your blood pressure, the greater your risk of kidney problems, according to a new report.

Analysis of data from the National Kidney Foundation's Kidney Early Evaluation Program (KEEP) also found evidence that more advanced stages of chronic kidney disease are present once a person passes the relatively mild blood pressure elevation of 130 mmHg.

KEEP is a voluntary, community-based screening program created in 2000 to boost awareness about kidney disease among people at high risk and to provide free testing and educational information.

Using Too Much Salt Is Common in U.S., CDC Says

New Guidelines for Treating Heart Failure

March 26, 2009
Criteria include added section on hospital care and advice on drugs most effective in blacks. New guidelines for treatment of heart failure are being issued by the American Heart Association and the American College of Cardiology, with a strong emphasis on management of people hospitalized for the condition and also on the treatment of blacks.

"The most important change is the addition of a new section on hospitalized patients," said Dr. Mariell Jessup, professor of medicine at the University of Pennsylvania and chairwoman of the guidelines writing group.

Registry Created for Broken Heart Syndrome

March 26, 2009
Data collection aims to aid in recognizing, treating rare but real condition. New details about the symptoms and outcomes of a relatively rare but potentially life-threatening condition called broken heart syndrome have been collected by U.S. researchers into a registry of people treated for the syndrome.

Music Can Help Restore Stroke Patients' Sight

March 25, 2009
Favorite melodies encourage brain healing, study suggests. Music may have charms to help restore sight to those recovering from a stroke, a new study finds.

Stroke survivors can suffer impaired visual awareness called visual neglect. It's caused by stroke-related damage in brain areas that integrate vision, attention and action, the researchers said.

Licorice May Block Absorption of Organ Transplant Drug

March 24, 2009
Study finds potential interaction with cyclosporine could lead to fatal complications. People taking the immunosuppressant cyclosporine should avoid consuming licorice because it may weaken the drug's effectiveness and possibly lead to deadly consequences, new research suggests.

Chemists in Taiwan report that lab rats taking cyclosporine .

Health Tip

Taking a Daily Aspirin

March 24, 2009
For some, it may not be safe A daily low-dose aspirin can help reduce the risk of heart attack in people with higher-risk conditions such as high blood pressure or diabetes.

While aspirin is generally safe, there are some people who shouldn't take it, since the drug can irritate the stomach lining.

The American Diabetes Association says the following people should talk to their doctor before beginning daily aspirin therapy:


People younger than age 21.

Lowest Blood Pressure, Cholesterol Levels the Best

March 23, 2009
Maximum benefit seen with tightest control of risk factors, researchers report. The tightest control of the major risk factors for heart disease seems to provide the greatest protection against cardiovascular trouble, a new study shows.

And so the current guidelines for risk factors such as blood pressure and LDL cholesterol might need to be tightened even further, said Dr. Stephen J.

Too Much Red Meat May Shorten Life Span

March 23, 2009
Major study finds an effect, but critics say meat offers important nutrients. Diets high in red meat and in processed meat shorten life span not just from cancer and heart disease but from Alzheimer's, stomach ulcers and an array of other conditions as well, a U.S. National Cancer Institute study has found.

Protein From Yellow Peas May Lower Blood Pressure

March 23, 2009
Finding in rats holds promise against kidney disease, too, experts say. Certain proteins found in the yellow garden pea appear to help lower blood pressure and delay, control or even prevent the onset of chronic kidney disease, at least in rats, a Canadian study has found.

"What we seem to have here is sort of a natural approach to treating this disease, as opposed to the normal pharmacological approach," said the study's lead author, Rotimi E. Aluko, an associate professor in the department of human nutritional sciences at the University of Manitoba in Winnipeg.

Genetics Should Decide Warfarin Dose, Study Reiterates

March 20, 2009
What works for some people might be dangerous for others. Researchers have confirmed previously reported genetic factors that may help doctors more accurately prescribe the proper dosage of the blood thinner warfarin to people at high risk of cardiovascular problems.

According to U.S.

Study Finds Millions More May Benefit From Statins

March 19, 2009
New prescribing criteria could prevent thousands of heart attacks. Cholesterol-lowering statins could cut the risk of heart attacks in as many as 6.5 million Americans who have low cholesterol but high levels of a blood marker for inflammation, researchers report.

Statins are known to prevent subsequent heart attacks and strokes in patients who've already suffered one of these cardiovascular events, and the drugs also protect people who haven't had a heart attack or stroke but are at increased risk for developing cardiovascular disease due to factors such as high cholesterol or diabetes.

Yale Lab Discovers New Gene-Based Syndrome

March 19, 2009

Mutation affects kidneys, brain and inner ear, study finds. A new syndrome that features seizures, lack of coordination, developmental delay and hearing loss has been identified by Yale University researchers. The syndrome was identified during a genetic analysis of 600 people for causes of salt-handling defects in the kidney that lead to high or low blood pressure. Five people from four families in Afghanistan, Canada, Great Britain and Turkey were found to have a range of neurological problems, in addition to a salt-handling defect.

Support Network May Play Role in Benefits of Drinking

March 19, 2009
Heart risks are found to be less pronounced in highly social men. Social support might enhance the cardiovascular health benefits of light-to-moderate drinking, suggests a Japanese study.

Heavy drinking increases the risk of stroke, but studies have linked light-to-moderate drinking with a reduced risk of ischemic stroke and coronary heart disease. Other research has found that people with higher levels of social support have a reduced risk of death and cardiovascular disease.

Experts Revise Guidelines on Daily Aspirin for Heart

March 16, 2009
Lower dose appears safe and effective against heart attack in men, stroke in women. Amid the continuing debate over who should pop an aspirin each day to fight heart disease, and at what dose, U.S. experts have revised guidelines stating that lower doses appear to be at least as effective as higher doses and safer at preventing heart attack and stroke.

Defibrillator May Not Help Many With Heart Failure

March 16, 2009
Elderly need to make tough choice on whether it's worthwhile, expert says. Implanted defibrillators don't seem to provide any particular benefit to many people with heart failure, a new study finds.

A defibrillator can provide a lifesaving electrical jolt when heart rhythm becomes abnormal enough to be fatal. But it generally does nothing for heart failure, the progressive loss of the heart's ability to pump blood nor does it help any life-threatening illness that might accompany heart failure, such as diabetes, cancer or kidney disease.

Study Questions Screening for Leg Vessel Blockages

March 16, 2009
Current guidelines may be set too high to catch disabling peripheral artery disease, experts say. Some people considered normal under current screening guidelines for peripheral artery disease (PAD) may be at high risk for loss of mobility, according to a U.S. study.

Preemie Delivery Tied to Later Heart Woes for Women

March 13, 2009
And ovary removal is another reproductive factor linked to cardiovascular trouble, research shows. The things that affect a woman's reproductive health can also have an effect on her heart, new research shows.

Giving birth prematurely or delivering a small-for-gestational-age baby are both associated with a later risk of cardiovascular disease in the mother, according to two studies expected to be presented Friday at an American Heart Association meeting in Palm Harbor, Fla.

A third study found that when women's ovaries were removed and the estrogen wasn't replaced through hormone therapy, a woman's overall risk of dying increased, as did her risk of dying of heart disease or stroke.

Firefighters Have Narrower-Than-Normal Arteries, Study Finds

March 16, 2009
Experts cite smoke, eating habits and sleep patterns as potential causes. Burning buildings might not be the only risks that firefighters face. They also appear to be more likely than their peers in other professions to have prematurely narrowed arteries, increasing their risk for strokes and heart attacks, according to a new study.

In fact, 22 percent of a group of 77 firefighters studied by researchers at the University of Kansas averaged 39 years old but had the blood vessels of 52-year-olds because of significant plaque buildup in their carotid arteries.

Some Elderly Heart Failure Patients Get Little Help From Meds, Study Finds

March 12, 2009
Experts say new drugs and guidelines are needed to treat diastolic dysfunction. Elderly people suffering from a type of heart disease called diastolic heart failure do not seem to benefit from the commonly prescribed heart failure drugs, researchers from Cedars-Sinai Medical Center in Los Angeles report.

As the population in the United States ages, more elderly people are being treated for heart failure. But even though they make up the majority of those treated for the disease, little is known about the effectiveness of treatment, researchers say.

Abnormal Heart Rhythm Boosts Death Risk for Diabetics

March 12, 2009
Blood pressure and cholesterol should be controlled more aggressively, study suggests. In people with diabetes, there's a strong association between abnormal heart rhythm, or atrial fibrillation, and increased risk of other heart-related problems and death, according to a study that included 11,140 people.

Researchers found that participants who had atrial fibrillation (AF) at the start of the study were 61 percent more likely to die from any cause, 77 percent more likely to die from cardiovascular causes such as a heart attack or stroke, and 68 percent more likely to develop heart failure or other problems such as stroke.

But the study also found that the risk of developing complications or dying was lower if doctors gave more aggressive treatments to diabetic patients with AF.

Neck Fat a Measure of Heart Risk

March 11, 2009
It signals danger independently of stomach fat, researchers report. A too-tight shirt collar might be an indicator of future heart trouble, Framingham Heart Study researchers report.

Doctors have long measured fat in the gut .

Migraines in Pregnancy Boost Vascular Risks

March 11, 2009
Headaches should be seen as indicator of other problems, expert says. Women who have migraines during pregnancy are 15 times more likely than other women to suffer a stroke, twice as likely to have heart disease and three times more likely to have blood clots and other vascular problems during pregnancy, says a U.S. study.

Ankle Blood Pressure Test May Spot Hidden Heart Risks

March 10, 2009
2 'unconventional' blood workups might also point out trouble, experts say. Simple but unconventional tests, such as blood pressure measurement taken at the ankle, could spot people with otherwise unsuspected heart risks, new research shows.

Many people who seem to be at low risk of cardiac problems by conventional standards actually have subtle signs of future trouble, noted a team from Brown University in Providence, R.I.

Antidepressant Use Tied to Cardiac Death in Women

March 10, 2009
But the drugs may indicate more severe depression, rather than direct cause-and-effect, researchers say. Women who use antidepressants appear to be at heightened risk for sudden cardiac death, although the exact nature of the link remains unclear, researchers say.

The finding doesn't necessarily mean that antidepressant drugs are dangerous, the researchers said.

"We suspect that their use is a marker for people with worse depression," explained study lead author Dr.

Second Stroke Prevention Efforts Found Wanting

March 05, 2009
Many patients not getting services they need to prevent another attack, researchers say After suffering a stroke, the chances of having another are high, but a new report shows many patients aren't getting the interventions they need to reduce that risk.

Those interventions include lifestyle changes, such as smoking cessation and exercise, and medical treatments, such as aspirin, blood pressure medications and cholesterol-lowering drugs.

"The overall use of many services was suboptimal, predominantly in the 60 to 80 percent range, where ideal would be that 100 percent received each item of care we examined," said lead researcher Dr.

Bad Marriages Harder on Women's Health

March 05, 2009
More likely than mates to show signs of metabolic syndrome in strained unions, study finds. The cardiovascular damage wrought by an unhappy marriage may be greater for women than men, a new study shows.

While both men and women in "strained" unions, those marked by arguing and being angry, were more likely to feel depressed than happier partners, the women in the contentious relationships were more likely to develop high blood pressure, high cholesterol, high blood sugar and other markers of what's known as "metabolic syndrome," said study author Nancy Henry, a doctoral candidate in clinical healthy psychology at the University of Utah.

Metabolic syndrome is known to boost the risk of heart disease, stroke and diabetes.

Even Mild Strokes Can Do Harm

February 27, 2009
But many people ignore the 'whisper' of trouble. If you knew you were having a stroke, you'd seek immediate medical attention. But what if your symptoms were mild or ambiguous?

Even people who experience vague symptoms of a stroke suffer mental and physical damage that diminishes their quality of life, researchers have found.

The implicit message? Don't wait for the worst to happen before reacting.

Views on Old Age May Become Reality Later

February 27, 2009
What you think now could determine your health as you age, study shows. New research suggests that young people who assume life is rough for seniors are more likely to suffer from heart attacks and stroke when they reach that age themselves.

"If people hold more negative views of aging, they may be less likely to walk the extra block or engage in healthy behaviors as they get older," explained study author Becca Levy, an associate professor of epidemiology and psychology at Yale School of Public Health.

The findings don't confirm that negative assumptions about aging in young people directly cause them to develop cardiovascular problems later.

Risk Score May Predict Abnormal Heart Rhythm

February 27, 2009
Could be first step in finding way to prevent atrial fibrillation, experts say. Weighing a combination of risk factors could help doctors predict which patients are the most likely to develop atrial fibrillation, a new study suggests.

To that end, the researchers have developed a risk score that might one day help prevent what has become the most common type of abnormal heart rhythm in the United States, affecting about 2.2 million people.

Lowering BP in Dialysis Cases Cuts Heart Risks

February 26, 2009
Study says drugs could prevent 2 of 10 deaths expected in every 100 patients per year. Blood pressure-lowering drugs should be routinely considered for dialysis patients, because it could protect them from major cardiovascular events and death, say researchers who reviewed the findings of eight clinical trials.

Those studies assessed the effects of lowering blood pressure in a total of 1,679 adult dialysis patients who experienced 495 cardiovascular events. The review authors found that treatment with blood pressure-lowering drugs reduced the risk of cardiovascular complications, cardiovascular deaths, and death by all other causes.

Men's Stroke Risk Rises Dramatically in Mid-40s

February 26, 2009
And the contributing factors are often those seen in older patients, study finds. The odds of having a stroke seem to spike up when men reach their mid-40s.

And the risks associated with stroke even at this earlier age are startlingly similar to the risk factors seen in older patients, a new study found.

"Silent strokes" .

Caffeine May Offer Some Skin Cancer Protection

February 26, 2009
It might one day be used as an ingredient in sunscreen, researchers say. Past studies have suggested that caffeine might offer some protection from skin cancer, and new research may explain why.

"We have found what we believe to be the mechanism by which caffeine is associated with decreased skin cancer," said lead researcher Dr. Paul Nghiem, an associate professor of dermatology at the University of Washington in Seattle.

Understanding Metabolic Syndrome

February 26, 2009
Factors that increase a person's risk of heart disease and diabetes Metabolic syndrome is a group of factors that combine to increase a person's risk of coronary heart disease, type 2 diabetes and other diseases, including stroke.

The American Heart Association offers this list of criteria for metabolic syndrome:


Excess fat around the abdomen.
High triglycerides, low HDL cholesterol and high LDL cholesterol.

Weak Evidence Backs Most Heart Guidelines, Report Finds

February 25, 2009
Experts agree that field needs more rigorous trials to aid doctors. A majority of the guidelines for cardiac care issued by the American Heart Association and the American College of Cardiology are not supported by the kind of gold-standard evidence that doctors respect most, a new study finds.

That conclusion does not come from heretics crying in the wilderness. One author of the report, published in the Journal of the American Medical Association, is Dr.

Women Less Apt to Get Clot-Buster, Study Finds

February 20, 2009
Some think gender inequality stems from different stroke symptoms in men and women. Gender definitely makes a difference when it comes to stroke, new research shows.

Not only can stroke show itself in slightly different fashion in women than it typically does in men, but women also don't get the gold standard of treatment for stroke as often as men do.

Those are two of several findings on women and stroke that were presented Thursday during a news conference at the International Stroke Conference in San Diego.

Early Menopause Doubles Stroke Risk

February 20, 2009
Experts suspect lowered estrogen levels might be a factor. Experiencing early menopause significantly raises a woman's risk for stroke, new research reveals.

"Women who reached menopause before age 42 had a doubling in the risk of ischemic stroke, compared to all other women," said Dr. Linda Lisabeth, an assistant professor of epidemiology at the University of Michigan School of Public Health and an author of the study.

Laser Therapy Disappoints in Stroke Trial

February 20, 2009
Treatment targeting damaged brain areas did not bring significant reductions in disability, researchers say. An experimental laser treatment of damaged brain areas failed to significantly reduce disability in stroke patients, researchers report.

The trial was the first major clinical study of "transcranial" laser therapy for stroke.

In the trial, the researchers at the University of California, San Diego used the NeuroThera laser system within 24 hours of stroke onset, with the average time to treatment being 14.

New Advances May Treat Stroke Faster, Better

February 20, 2009
Innovations include 'brain stents' and a clot-busting drug delivered directly to the brain. Tiny tubes called stents, used for years to open blocked coronary blood vessels, may also work well to reopen brain blood vessels clogged from strokes, according to new research.

A variety of other advances promise to improve stroke treatment or prevention as well, a panel of researchers said. Among the developments, presented Thursday at the International Stroke Conference in San Diego:

Using new delivery systems to make a medication more effective in breaking up clots in the brain;

Finding new genetic clues to predict who might develop an aneurysm, a weakened brain blood vessel that can rupture and cause a devastating hemorrhagic stroke;

Treating people who have low cholesterol levels but elevated levels of a stroke-linked inflammatory marker with the anti-cholesterol drug Crestor, which nearly halved users' risk for stroke in a recent trial.

Coffee or Tea Consumption May Lower Stroke Risk

February 20, 2009
Drinking more of either beverage seems to bestow benefits, studies show. Here's some good news for java junkies and tea lovers alike: Two new studies suggest that both beverages may lower your stroke risk.

As coffee drinking increases, the prevalence of stroke decreases, said Dr. David Liebeskind, author of the coffee study and an associate clinical professor of neurology at the University of California, Los Angeles.

Few Stroke Patients Get Clot-Busting Drug

February 20, 2009
tPA can reduce disability, but less than 3% of Medicare patients receive it, study shows. A powerful clot-busting drug approved by the U.S. Food and Drug Administration for use in stroke patients in 1996 is still rarely used in Medicare patients, new research shows.

More Fast-Food Joints in Neighborhoods Mean More Strokes

February 19, 2009
Analysis is interesting, but doesn't prove cause and effect, researchers says. Living in neighborhoods packed with fast-food joints could increase your risk for stroke by 13 percent, compared to residing in places where such restaurants are less plentiful, a new study suggests.

Whether the link proves to be causal is not known, though, said study author Dr. Lewis B.

Know the Warning Signs of Stroke? Most Don't.

February 19, 2009
People at greatest risk seem to know the least, survey finds. Most people do not know the five warning signs of a stroke and what to do if they suspect one .

B Vitamins Might Lower Stroke Risk

February 19, 2009
But jury is still out on their value, experts note. People with heart disease who take high doses of B vitamins are somewhat less likely to suffer from stroke, especially if they're under 70, a new Canadian study suggests.

But other studies have come to opposite conclusions about whether vitamins really protect against cerebrovascular disease, noted Dr. Larry B.

Obesity, Lack of Insurance Take Toll on Young Americans

February 19, 2009
CDC annual report on nation's health focuses on those aged 18 to 29. Increased rates of obesity and lack of insurance coverage are among the many health challenges facing young American adults, according to just-released statistics.

A special section on young adults between the ages of 18 and 29 is featured in the annual report on the nation's health from the U.S.

Genetics May Help Fine-Tune Warfarin Dosage

February 18, 2009
Formula that includes DNA data proves faster, more accurate in early tests. A DNA test could make prescribing the widely used anticoagulant warfarin safer by predicting the lowest effective dose, a new study finds.

ER Less Likely to Diagnose Stroke in Younger Folks

February 18, 2009
New research finds misdiagnosis risk goes up as age goes down. An 18-year-old boy complaining of numbness at a Detroit emergency room was discharged after health-care professionals determined he was drunk.

A 24-year-old woman with sharp pain in her left eye and loss of feeling in her right arm was told by ER doctors that she had a migraine.

And a 29-year-old man with slurred speech, a facial droop and vertigo was diagnosed with peripheral vertigo during his emergency room visit.

Silent Strokes More Common in Younger People Than Thought

February 18, 2009
The symptomless events are 5 times more prevalent than full-blown stroke in people under 65, MRI study shows. "Silent strokes" rarely produce symptoms, but a new study suggests they may be at least five times more common than full-blown strokes in people under 65 years of age, and not uncommon in people under the age of 50.

The new study was conducted by a team at Boston University School of Medicine as a part of the ongoing Framingham Heart Study. The researchers performed brain MRI's on 1,059 people and then followed 925 individuals who showed no evidence of silent stroke, known as silent cerebral infarcts (SCI).

Working With Robots May Help After a Stroke

February 18, 2009
People who lost use of a hand recaptured movement, study finds. Robotic therapy might help stroke victims regain some of their impaired physical abilities, even if it's been years since the debilitating event.

People with partial paralysis on the right side after a stroke were better able to use their hands to pick up, hold and move objects after they participated in robot-assisted practice grabbing and releasing objects, according to research scheduled to be presented this week at the International Stroke Conference in San Diego.

All 15 participants in the study showed some improvement after the robotic treatment, but those who had less physical impairment at the start of the therapy improved the most.

Fast Arrival at Hospital After Stroke Pays Off

February 19, 2009
These patients were twice as likely to get clot-busting drug, study shows. People who get to a hospital no more than an hour after having the first symptoms of a stroke are twice as likely to get the powerful clot-dissolving drug that is the first line of treatment, a new study finds.

Of the more than 100,000 people treated for stroke at American hospitals, 27.1 percent of those whose treatment began within a hour of the first symptoms received tissue plasminogen activator (tPA), according to a report to be delivered Wednesday at the American Stroke Association's International Stroke Conference, in San Diego.

Exploring Genetic Link Between Migraines, Cardiovascular Trouble

February 17, 2009
Suspected variant is not a player, but two genotypes might be, study finds. In a finding that speaks to the complicated connection between having migraines with aura and an increased risk of cardiovascular trouble, Harvard researchers report that a gene variant that was suspected to be a link between the conditions is not but that two genotypes could well be.

"Migraine with aura, in women in particular, is associated with about a doubling of the risk of stroke and heart attack," said Dr. Richard Lipton, director of the Montefiore Headache Center in New York City.

Coffee Drinking Lowers Women's Stroke Risk

February 16, 2009
Study finds those who had two or more cups a day gained protection, unless they smoked. Drinking coffee appears to lower the risk for stroke among women, with more consumption translating into more protection, Spanish and American researchers suggest.

The finding stems from the tracking of both coffee habits and stroke occurrence among tens of thousands of American women across nearly a quarter century. And it adds to earlier indications that coffee might also offer some protection against diabetes, while not raising the risk for heart trouble.

Genes That Control Body's Salt Levels Are Identified

February 16, 2009
Whether finding will lead to treatment improvements remains unclear. The largest study of the effects of genetics on blood pressure in humans has linked variant versions of genes that control levels of salt in the body with high blood pressure, a major risk factor for heart disease and stroke.

"There have been hundreds of genes and gene variants reported to be related to blood pressure," said Dr. Christopher Newton-Cheh, assistant professor of medicine at Harvard Medical School and the Center for Human Genetic Research at Massachusetts General Hospital and lead author of a report in Nature Genetics.

Salt Boosts Blood Pressure in High-Risk Patients

February 16, 2009
Metabolic syndrome may enhance sodium's effect on the body, study suggests. Salt intake has more of an effect on blood pressure in people with metabolic syndrome than in others, experts say, suggesting that cutting down on salt could be especially important for these high-risk individuals.

About one in five people are affected by metabolic syndrome, a combination of three or more conditions that increase the risk of developing cardiovascular disease and diabetes. Those conditions include abdominal obesity, elevated blood pressure, high triglyceride concentration, low HDL cholesterol, and high glucose levels.

Being Heart Smart Just Makes Sense

February 15, 2009
Knowing the early warning signs of an attack can greatly increase survival, group says. Knowing all the warning signs of a heart attack greatly increases the chances of surviving one, says the American College of Emergency Physicians (ACEP).

"Everyone knows that a heart attack can start with severe chest pains. But early signs can also include shortness of breath, unexplained weakness or palpitations," Dr.

Secondhand Smoke Linked to Dementia

February 13, 2009
Exposure may increase risk by 44%, researchers say. People exposed to secondhand smoke may face as much as a 44 percent increased risk of developing dementia, a new study suggests.

While previous research has established a connection between smoking and increased risk for dementia and Alzheimer's disease, this new study is the largest review to date showing a link between secondhand smoke and the threat of dementia, the authors said.

"There is an association between cognitive function, which is often but not necessarily a precursor of dementia, and exposure to passive smoking," said lead researcher Iain Lang, a research fellow in the Public Health and Epidemiology Group at Peninsula Medical School in Exeter, England.

Long-Term Aspirin Use Seems to Protect Against Colorectal Lesions

February 10, 2009
The benefit lasts even if you stop taking the drug, study finds. Prolonged use of low-dose aspirin or other nonsteroidal anti-inflammatory drugs (NSAIDs) appears to reduce the risk of precancerous lesions that can lead to colorectal cancer.

That's the conclusion of a new study of people at high risk for the disease.

"It's increasingly clear, and arguably proven, that NSAID drugs do interfere with the development of cancer in the large bowel," said study co-author Dr.

Gender Disparities Persist in Treatment of Stroke

February 10, 2009
Raft of studies points up many of the differences in care, incidence of brain attacks. Significant gender differences continue to persist with stroke, not only in its incidence, but also in its prevention and treatment.

Among other things, women with stroke are more likely to experience emergency room delays and less likely to be treated aggressively for risk factors beforehand, according to a raft of studies coming out in a specially themed April issue of Stroke. The findings were released this week to coincide with Go Red for Women Day.

Vitamins Do Older Women Little Good

February 09, 2009
Study finds they don't reduce risk of cardiovascular disease, cancer. In yet another blow to the dietary supplement industry, researchers find no evidence that multivitamin use helps older women ward off heart disease and cancer, the top two killers of women, respectively.

"Women can be encouraged by the fact that these vitamins seem to do no harm, but they also seem to confer no benefit," said study co-author Sylvia Wassertheil-Smoller, a professor of epidemiology and population health at Albert Einstein College of Medicine in New York City. "The kind of vitamins you get from diet is quite different, because foods are very complex and have a lot of chemicals we don't know about that interact with each other.

Genetic Test for Heart Disease Risk in the Works

February 09, 2009
International studies lay groundwork for designing way to spot susceptible patients. Perhaps five years from now, you might actually hear your doctor casually say, "While we're at it, let's do a blood test to see if your genetic makeup puts you at high risk of having a heart attack."

So says Dr. Sekar Kathiresan, an assistant professor of medicine at Harvard Medical School and director of preventive cardiology at Massachusetts General Hospital.

Female Hormones Deter Salt-Sensitive Hypertension

February 06, 2009
Estrogen appears to improve kidneys' ability to shed sodium, study says. Hormones and a cell receptor in the kidneys may explain why premenopausal women have fewer problems than men with salt-sensitive hypertension, a new study says.

Salt-sensitive hypertension occurs when the kidneys hold onto more sodium than necessary. This drives up blood pressure as the body tries to force the kidneys to get rid of excess salt.

Quick Stroke Treatment Improves Outcomes

February 05, 2009
Rapid action cuts death rate, costs, length of stay and risk of recurrence, study finds. Rapid assessment and treatment in a specialist emergency outpatient clinic reduces death, disability, costs and hospital bed-days experienced by patients who suffer a minor stroke or transient ischemic attack (TIA), British researchers report.

The results represent the second part of what is known as the EXPRESS study.

There's an 8 percent to 10 percent risk of recurrent stroke in the first few days after a minor stroke or TIA.

Inflammation May Play Role in Sleep Duration

February 02, 2009
Stress, mood affect cytokine regulators underlying resting habits, study says. Inflammation may play a role in the health of people who sleep too little or too much, according to a U.S. study that included 614 people.

Stroke Drug Might Be a Memory-Booster

February 02, 2009
Fasudil improved the recall of middle-aged rats, scientists say. Fasudil, a drug used for a decade to safely treat people with vascular problems in the brain, appears to improve some learning and memory abilities in middle-aged rats, a new study says.

The findings, published in the February issue of Behavioral Neuroscience, give researchers hope of finding a way to combat the normal decrease in cognitive function experienced by humans as they age.

Rats injected with hydroxyfasudil, the active ingredient in Fasudil, performed better on a maze that tested their spatial learning and working memory than those given a placebo.

Preeclampsia in Pregnancy Boosts Future Health Risks

January 30, 2009
Moms may face lifelong chance of hypertension, diabetes and blood clots, study says. Women who experience preeclampsia during pregnancy are at increased risk for future health problems such as hypertension, diabetes and blood clots, American and Danish researchers report.

Preeclampsia is a complication of pregnancy linked to life-threatening cardiovascular disease.

The researchers analyzed data on more than 11 million women who gave birth in Denmark from 1978 to 2007.

Top 10 Heart-Stroke Advances for 2008

January 30, 2009
Research looked at smoking bans, acute care, diabetes control and childhood obesity Studies on smoking bans, acute care of heart attack and stroke patients, diabetes control and childhood obesity were among the top 10 major advances in heart disease and stroke research in 2008, according to the American Heart Association.

"It's always difficult to choose from among such a broad array of new discoveries," AHA President Dr. Timothy Gardner said in an AHA news release.

Omega-6 Fatty Acids Can Be Good for You

January 26, 2009
New advisory puts worries about possible link to heart disease to rest. All that discussion about the omega-6 fatty acids found in vegetable oils, nuts and seeds possibly being bad for your heart is unfounded, a new science advisory from the American Heart Association claims.

"There has been a lot of talk in the nutrition world that omega-6 fatty acids might be bad," said William S. Harris, the nutritionist heading the committee that issued the report in the Jan.

60 Million Worldwide Carry Heart Disease Mutation

January 23, 2009
Muscle protein variant, most common in India, leaves carriers with little warning of dangers. About 60 million people worldwide carry a gene mutation that almost always causes heart disease, but the mutation is most common among people in India, according to a study by 25 researchers from four countries.

Heart disease is the leading cause of death in the world. By 2010, India will account for about 60 percent of the world's heart disease, said the researchers, who analyzed the DNA of about 800 patients at cardiac centers in India.

New Brain Hemorrhage Guidelines Stress Quick Action

January 22, 2009
Hospitals with more expertise handling these attacks also boost survival outcomes. Brain hemorrhage patients have better outcomes when they're treated quickly and at hospitals that handle many brain attack emergencies, according to updated guidelines released by the American Heart Association.

Subarachnoid hemorrhage (SAH) occurs when a blood vessel bursts and bleeds into the brain's subarachnoid space .

Moderate Alcohol Consumption May Protect Against Disabilities

January 22, 2009
Study found healthy older adults were better able to carry out daily tasks. Healthy people 50 and older who drink alcohol moderately are less likely to suffer physical disabilities that cause so many seniors to lose their independence, a new study says.

The study authors said their research showed that healthy older adults who were light-to-moderate drinkers had 25 percent lower odds of being unable to carry out daily activities such as walking, dressing, eating, running errands or doing chores.

Conversely, heavy drinkers and abstainers had higher risks of disabilities that would limit such activities.

Kidney, Heart Problems May Be Linked

January 21, 2009
Older people face more risks when kidneys are damaged, study finds. Damaged kidneys could put older adults at a greater risk of heart failure, stroke and other cardiovascular disease, a new report says.

The University of Glasgow study of adults ages 70 to 82 found that participants whose kidney function was most impaired had a three times greater risk of having non-fatal heart failure or heart disease and were more likely to die from the heart conditions as were those with healthier kidneys. They were also twice as likely to die from any cause as were people with healthier kidneys.

Simple Exercise Keeps Brain at Top of Its Game

January 20, 2009
In older women, being more fit helps cognitive function, study shows. Physical fitness may be as good for the brain as it is for the body in old age, a new study says.

A study of Canadian women older than 65 found that those who took part in regular aerobic activity had cognitive function scores 10 percent higher than their peers who did not exercise. The active women also had lower blood pressure (at rest and during exercise) and better vascular responses in the brain, suggesting that better blood flow aids the ability to think, the study found.

Abnormal Heart Function Reduces Exercise Capacity

January 20, 2009
Older patients were more affected, study found. Abnormal heart function greatly reduces a person's ability to exercise, say U.S. researchers.

Angioplasty Via Wrist May Be Safer

January 20, 2009
It's seldom used but entails lower risk, speedier recovery, researchers say. The best way of accessing and treating ailing hearts with angioplasty may be through the wrist, a U.S. study finds.

Cholesterol Levels May Not Measure Cardiac Risk

January 16, 2009
Normal readings showed up in many who had heart attacks, study shows. Nearly three-quarters of patients hospitalized for heart attacks had cholesterol levels indicating they were not at high risk for cardiovascular trouble, a new, nationwide study shows.

The finding points to the possibility that current guidelines on cholesterol levels should be changed, said study author Dr. Gregg C.

Sleep Apnea Seems to Wear Down the Brain

January 15, 2009
Repeated blood flow changes may be at the root of higher stroke risk, study says. Repeated surges and drops in blood pressure and blood flow in the brain might make people with sleep apnea more prone to have a stroke and die in their sleep, a new study says.

The Yale University School of Medicine study found that obstructive sleep apnea causes a decreased blood flow to the brain during episodes. When this happens, the organ's blood pressure rises.

Newer Contraceptives Don't Increase Heart Risk

January 15, 2009
But more research is needed because they may lead to blood clots, study says. Newer formulations of birth control pills don't seem to increase the risk of heart disease as much as older forms did, a new study says.

But more research on the newer generations of contraceptives is needed to delineate the specific effects. This is especially true because more women over age 35 are taking hormonal contraceptives, they're taking them for longer periods of time, and the U.

Blood Flow Measurement Boosts Stent Outcomes

January 14, 2009
Technology reduces deaths, complications, but may be too costly for some centers, experts say. A sophisticated measure of blood flow to determine where artery-opening stents should be implanted is more effective than the X-ray examinations now commonly used, an international study finds.

The technique, measuring what's known as "fractional flow reserve" (FFR), is designed for people who have multiple blockages that require artery-opening procedures such as angioplasty, followed by implantation of the flexible tubes called stents, explained study co-author Dr. Nico H.

Millions More Americans Might Be Placed on Statins

January 13, 2009
Recent data could lead to wider prescribing of cholesterol-lowering drugs, experts say. If doctors start taking results of a recent drug company-sponsored trial seriously, 11 million more older Americans might be taking cholesterol-lowering statin medications, experts say.

Results from the JUPITER trial were first reported in November 2008. The study was cut short, because treatment with Crestor (rosuvastatin) .

Women With Heart Attack Symptoms See Delays in Care

January 13, 2009
Differences in initial symptoms could explain discrepancy, study suggests. Women calling 911 with cardiac symptoms took longer than men to get to the hospital after an emergency medical services team had arrived in response to the call, a new study found.

It's not clear why this was the case, but a number of gender differences exist when it comes to heart attacks. In particular, differences in initial symptoms could explain much of this delay, said the authors of the study, which appears in the Jan.

Sodium, Potassium Intake Tied to Heart Disease

January 12, 2009
Study finds 24% greater risk per unit increase in salt-to-mineral ratio. Too much sodium and too little potassium in one's diet may increase one's risk of cardiovascular disease, a new study suggests.

The findings, based on a long-term analysis by the U.S.

Cold Weather May Raise Blood Pressure in Elderly

January 12, 2009
Seasonal variance suggests target for better treatments. When the temperature drops outside, blood pressure appears to rise in older adults, a new study shows.

The systolic (top number) and diastolic (bottom number) blood pressures both rose and fell with the change of seasons in the 8,801 people, aged 65 or older, looked at in the study by the Institut National de la Sante et de la Recherche Medicale of Paris. The average systolic blood pressure, for example, was five points higher in winter than in summer for the participants.

Framingham Score May Not Spot Lifetime Heart Risk

January 12, 2009
Study is third in a week to question some facet of the widely used guideline. As many as half of people aged 50 and younger who have a low 10-year risk of heart attack or stroke based on the widely used Framingham Risk Score may still have a high lifetime risk.

That's the conclusion of a new study published in the Jan. 13 issue of Circulation.

The study, backed by the U.S.

Viagra May Shield Heart From Blood Pressure Damage

January 05, 2009
Sildenafil appears to delay dangerous heart muscle expansion in mice.
Tests in mouse hearts show that sildenafil, the key ingredient in Viagra, may shield hearts from damage caused by high blood pressure, a new study suggests.

Investigators said that sildenafil appears to influence RGS2, a single protein essential in the reactions that initially protect the heart's blood-pumping function from spiraling into heart failure. The findings, published online Monday in The Journal of Clinical Investigation, suggest that sildenafil may prove useful in the treatment or prevention of heart damage due to chronic high blood pressure.

When the Heart Stops Beating

January 05, 2009
Survivors tell their stories of sudden cardiac arrest. Deanna Babcock's heart stopped beating on July 20, 2007. Just like that.

"I was swimming in a pool at North Carolina State University, doing normal laps," recalled Babcock, who was 23 years old and in excellent health, or so she thought.

Human Body May Make Its Own 'Aspirin'

December 31, 2008
Theory stems from presence of salicylic acid in study participants. Salicylic acid, the key component that gives aspirin its anti-inflammatory and pain-relieving properties, may be something humans can produce on their own, a new study suggests.

Salicylic acid (SA) previously had been found in the blood of people who had not taken aspirin recently .

Dubious Drugs, Tainted Foods Top 2008's Health Stories

December 31, 2008
But deaths from heart disease, cancer show encouraging drop. Doubts over the safety of diabetes and heart treatments, disappointing results for vitamins as cancer fighters, and the withdrawal of over-the-counter cold medicines for kids were some of 2008's top health stories.

But there was good news, too, including a historic drop in deaths from both heart disease and cancer, and a breakthrough in the search for a malaria vaccine.

Here are some of the biggest health headlines for 2008:

Troubles Surface for Heart, Diabetes Treatments

Throughout 2008, data emerged supporting the notion that two blockbuster diabetes medications .

Optimal Warfarin Dosing Improves Anticoagulation Control

December 30, 2008
Increasing time within the therapeutic range of utmost importance, study finds. While the anticoagulant warfarin can be highly effective in preventing strokes and treating venous thromboembolism, doctors have long struggled with finding the best way manage the drug therapy.

Boston University School of Medicine (BUSM) researchers now claim to have figured out the optimal dosing levels to help patients, according to a study published in December online issue of the Journal of Thrombosis and Haemostasis.

The research team analyzed warfarin use in almost 4,000 patients to determine what are the most effective levels of the drug in a patient's system under different circumstances.

Guide on Blood Thinner Now Available in Spanish

December 29, 2008
Brochure may help spread the word about warfarin's possible complications. A new pamphlet has been published to help Spanish-speaking patients understand what to expect and watch for while taking the blood thinner warfarin.

Millions of Americans take warfarin, available under the brand name Coumadin, because they have an irregular heartbeat (known as atrial fibrillation), they've had a heart attack, or they are trying to prevent or treat blood clots in the legs or lungs.

But warfarin is the second most common drug .

Gene Ups Risk for Those on Blood-Thinner Plavix

December 23, 2008
Younger patients with the mutation faced higher odds of heart attack, death, studies found. A gene variation can make younger heart attack patients more prone to another heart attack, death or other heart problems if they receive the anti-clotting drug Plavix, a trio of new studies finds.

One study is published in the Dec. 23 online edition of The Lancet, while two more studies with similar results will appear in the Jan.

Not All Dementia Is Called Alzheimer's

December 19, 2008
Vascular cognitive impairment impedes ability to organize thoughts, but it is preventable. A common form of dementia often mistaken for Alzheimer's can be prevented with good health habits, a new report says.

Vascular cognitive impairment (VCI), the second most common cause of dementia, occurs in up to 4 percent of Americans over age 65 and up to 20 percent of those with some form of dementia. Brain damage from multiple small strokes, which can occur from narrowing or blocked arteries in the brain, are often the cause of VCI.

Depression, Anxiety Hinder Quality of Life After Stroke

December 18, 2008
Rehab efforts should focus on personality, coping styles to boost outcomes, study says. Many people who survive a subarachnoid hemorrhage stroke have a poor quality of life due to anxiety, depression and fatigue, Dutch researchers report.

A subarachnoid hemorrhage (SAH) stroke occurs when a blood vessel on the brain surface ruptures and bleeds into the space between the skull and the brain, but not into the brain. This study included 141 women and men, average age 51, living in the community two to four years after an SAH stroke.

Study Finds Molecular Link Between Obesity, Hypertension

December 17, 2008
Signaling through the melanocortin-4 receptor controls blood pressure, study shows. Most people know that obese individuals tend to have high blood pressure, but now British researchers have identified the molecular pathway that could explain that link.

In findings published in the Dec. 17 online issue of the New England Journal of Medicine, Sadaf Farooqi, of the University of Cambridge, and her colleagues demonstrated that signaling through the melanocortin-4 receptor (MC4R) helps to regulate blood pressure in humans.

Strict Blood Sugar Lowering Won't Ease Diabetes Heart Risk

December 17, 2008
Blood pressure, cholesterol control may be type 2 diabetics' best bet, researchers say. Intensive lowering of blood sugar in people with poorly controlled type 2 diabetes does not have a significant effect on reducing cardiovascular events, such as heart attack and stroke, a new study finds.

"You can decrease cardiovascular events in patients with type 2 diabetes by good treatment of lipids [cholesterol], blood pressure and other cardiovascular risk factors," noted lead researcher Dr. William Duckworth, from the Phoenix Veterans Affairs Health Care Center in Arizona.

Small Doses of Carbon Monoxide Might Help Stroke Victims

December 16, 2008
Mouse study showed it reduced brain damage after attack. It's a potentially lethal gas, but small amounts of carbon monoxide (CO) may help prevent brain damage after a stroke, Johns Hopkins researchers report.

CO, a colorless, odorless gas that can cause organ damage and death, is found in combustion fumes, such as those made by heating systems, vehicles and gas ranges. In enclosed or semi-enclosed places with poor ventilation, CO can build up and pose a serious threat.

Program Aids Hospital Compliance With Stroke Guidelines

December 16, 2008
Goal is to improve use of treatments proven to cut post-illness complications. U.S. hospitals enrolled in a voluntary program to improve stroke patient treatment increased their adherence to national recommendations, according to a five-year study that included 790 hospitals that provided data on 322,847 stroke patients admitted from 2003 to 2007.

Children of Centenarians Face Lower Heart Risks

December 16, 2008
Finding adds weight to belief that longevity runs in families. Longevity runs in families, the saying goes, and new research shows there may be genetic and physiological reasons for the phenomenon.

The children of people who live to 100 and beyond are themselves much less likely to develop cardiovascular diseases, such as heart disease and stroke, and even diabetes, researchers found.

But they aren't impervious to non-cardiovascular health problems, such as cancer, dementia and depression.

Deaths From Heart Disease, Stroke Down 30%

December 15, 2008

Stress Triggers Heart-Damaging Behavior

December 15, 2008
Study found the dynamic raised cardiovascular risks by 50%. Stress increases the risk of heart attack and other cardiovascular problems by pushing people toward bad habits, new British research suggests.

"The study suggests that people with psychological stress had a 50 percent increased risk of a cardiovascular disease event over the follow-up period," said Mark Hamer, senior research fellow in epidemiology and public health at University College London, and lead author of a report in the Dec. 16/23 issue of the Journal of the American College of Cardiology.

Fast Heart Rate Warns of Obesity, Diabetes

December 11, 2008
And those conditions take toll on the heart, study says. A too-fast heartbeat in early adulthood is a warning sign for increased risk of cardiovascular problems decades later on, a Japanese study suggests.

The study of 614 residents of a rural farming community in southwestern Japan found that a heart rate greater than 80 beats a minute during a first examination in 1979 predicted the development of obesity and diabetes, which contribute to heart problems.

The findings, from Kurume University School of Medicine, were published online Dec.

Defect in Gene Tied to Atrial Fibrillation

Avoiding a Holiday Season of Discontent

December 06, 2008
Stress is everywhere, but learning what relaxes you can help, expert says. For many people, stress is as much a part of the holiday season as family gatherings and good food.

But learning the art of relaxation can help relieve social, financial and other pressures that can take the fun out of this time of year, according to Julie Kosey, manager of integrative health coaching at Duke Integrative Medicine.

"Relaxation is a right, not a privilege," Kosey said in a Duke news release.

Lung Disease Tied to Increased Risk for Cardiac Events

December 05, 2008
IPF patients 3 times more likely to suffer heart problems, study says. People with the deadly lung disease idiopathic pulmonary fibrosis (IPF) are three times more likely than people without the disease to suffer severe cardiac events such as a heart attack, according to a British study.

"If you look at them over time, people with IPF have roughly a threefold increased risk of acute coronary syndrome, which is a greater increase than you get from smoking," lead author Dr. Richard B.

Preemies' Low Blood Pressure Linked to SIDS

December 01, 2008
Preterm infants already at higher risk for SIDS and this may be why, researchers say. Premature infants often have lower-than-normal blood pressure that persists during the first six months of life and may be one reason these infants are more prone to sudden infant death syndrome (SIDS), Australian researchers suggest.

One theory of the cause of SIDS is a profound drop in blood pressure during sleep, from which the infant cannot recover.

Heavy Traffic Can Be Heartbreaking

November 30, 2008

Ultrasound Can Help Break Up DVTs

November 24, 2008

Adding it to clot-busting drug eased the blockages, study found.  A combination of ultrasound waves and clot-busting drugs may help dissolve blood clots quicker than drugs alone in patients with deep vein thrombosis (DVT), according to an Emory University School of Medicine study. DVT refers to a blood clot that forms in a vein deep in the body, most often in the lower leg or thigh.

High Blood Pressure Stalks Many Americans

November 21, 2008

It's one of medicine's mantras: If you have high blood pressure, taking steps to lower it will have a dramatic impact on your risk of stroke, heart disease and more.
