For Chest Pain in the ER, CT Angiography May Be Best
November 19, 2009
Procedure cuts diagnosis time and costs, study finds. Compared to standard emergency room triage, CT angiography is quicker, more accurate and much less expensive for screening patients with chest pain who have low to moderate enzyme and EKG scores, according to a new study.
The study included 749 acute chest pain patients at 16 emergency rooms who were randomly assigned to receive either coronary computed tomographic angiography (CCTA) or standard screening with myocardial perfusion imaging (MPI).
Both methods were found to be safe, and similar numbers of patients underwent invasive angiography during the first visit.

Diet, Cognitive Ability May Play Role in Heart Disease
November 19, 2009
Study finds fewer deaths among higher-functioning seniors who eat lots of fruits, vegetables. Seniors who eat plenty of fruits and vegetables and who have good cognitive function are much less likely to die from heart disease than those who have poorer cognitive function and eat fewer fruits and vegetables, a new study has found.
Cognitive function refers to the ability to think, remember, plan and organize information.
Researchers at the Drexel University School of Public Health in Philadelphia analyzed diet and cognitive data on 4,879 people (3,101 women and 1,778 men), age 70 and older, who took part in the U.

Newer Blood Thinners May Outperform Old Standbys
November 18, 2009
Studies found warfarin, Plavix bested by latest anti-clotting alternatives. After years of little progress, three new trials suggest that the latest generation of blood thinners may outperform the old standbys warfarin and clopidogrel (Plavix).
In one study, dabigatran etexilate (marketed as Pradax in Canada and Pradaxa in Europe; it is not yet approved in the United States) proved to be safe in preventing blood clots when patients were treated for acute coronary syndrome, a cluster of symptoms that might indicate a heart attack.
"Dabigatran seems to be safe on top of dual antiplatelet therapy [meaning aspirin and Plavix]," said study author Dr.

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.

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.

Viagra Helpful for Children With Heart Defect
November 17, 2009
Pumping ability improved with sildenafil in study group. The erectile dysfunction drug sildenafil, commonly known as Viagra, boosts the heart's pumping ability in children and young adults who've had the Fontan operation to correct single-ventricle heart defects, researchers report.
In the Fontan operation, doctors direct venous blood directly to the pulmonary arteries, bypassing the heart. The procedure is the third surgery in staged reconstruction for children with single-ventricle defects, explained the researchers from the Children's Hospital of Philadelphia in a news release from the American Heart Association.

Stem Cells May Improve Heart Bypass Results
November 17, 2009
Patients who had bone marrow transplant with surgery did better, study finds. Patients who received bone marrow stem cell transplants during coronary bypass surgery (CABG) experienced "excellent long-term safety and survival," say German researchers, who also noted the first promising results for stem cell transplantation during mitral valve repair.
The study included 35 patients who received CD 133+ bone marrow stem cell transplantation during CABG, 20 patients who received only CABG surgery and 10 patients who received stem cell transplantation after mitral valve repair.
Long-term survival among patients in the stem cell transplant/CAGB group was up to five years.

Oil from engineered beans might help reduce heart attacks, researchers say. Oil from genetically modified soybeans boosts levels of an important omega-3 fatty acid in the body, which may reduce the risk of heart attacks, U.S. researchers say.
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.

Study Raises New Questions About Cholesterol Drug Zetia
November 16, 2009
It was found less effective than extended-release niacin, or Niaspan. A new study raises more questions about ezetimibe (Zetia), a drug used by millions of Americans in tandem with statins to lower LDL, or "bad," cholesterol.
The trial, known as ARBITER-6 HALTS, was stopped early in June after it was discovered that LDL-cholesterol-lowering Zetia was less effective than extended-release niacin (Niaspan), which raises HDL, or "good," cholesterol levels, in reducing plaque build-up in the arteries.
Clinical trials are generally terminated early if a safety issue arises, less so when a measure of success is achieved.

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.

Alternative to Warfarin May Cut Risk of Bleeding
November 16, 2009
Dabigatran etexilate does well in trial of atrial fibrillation patients. The anti-clotting drug dabigatran etexilate (Pradaxa) may be more effective and safer than warfarin at preventing clots and stroke in patients with atrial fibrillation, a new Swedish study has found.
Warfarin is effective in preventing blood clots that can cause stroke in patients with atrial fibrillation (abnormal heart rhythm) and other diseases, but the drug has a narrow therapeutic range in which it prevents strokes but doesn't cause bleeding, according to the researchers. This means that effective warfarin treatment requires regular laboratory monitoring to ensure warfarin levels remain in the range that lowers the risk of stroke without increasing the risk of bleeding.

Families Could Benefit From Gene Tests in Sudden Cardiac Death Victims
November 16, 2009
Identifying mutation in deceased cuts costs for evaluating risk in relatives, study shows. Genetic testing of people who've suffered sudden unexplained death is an effective and cost-efficient way of identifying genetic mutations that may put surviving relatives at increased risk for potentially deadly heart rhythm disturbances, a new study suggests.
Genetic defects that can cause sudden cardiac death occur in 25 percent to 30 percent of victims of sudden unexplained death. The current recommended approach is for first-degree relatives of sudden unexplained death victims to undergo comprehensive cardiac testing.

Cholesterol Measurements May Be Made Easier
November 10, 2009
Testing of vascular risk can be simplified, researchers say. Methods to gauge blood cholesterol to determine vascular disease risk can be simplified, researchers in England say.
Their method measures levels of either total or high-density lipoprotein (HDL, or "good" cholesterol) in the blood or apolipoproteins (proteins that help transport cholesterol), without the need to have patients fast and without regard to another form of blood fat called triglycerides.
"Expert opinion is divided" on which combination of measurements is ideal in gauging cardiovascular risk, explained John Danesh, of the Emerging Risk Factors Collaboration Coordinating Centre at the University of Cambridge, and colleagues.

Stroke Puts Stress on Spousal Relationship
November 10, 2009
Patient/caregiver roles often take the place of a partnership, researchers say. Although many wedding vows include the phrase "in sickness and in health," a stroke can put that promise to the test by causing major relationship problems for married couples, according to British researchers.
The University of Ulster study included 16 married stroke survivors (nine males, seven females), aged 33 to 78. The time since their stroke ranged from two months to four years, with an average of 18 months.

Can a Bad Boss Make You Sick?
November 06, 2009
Study ties poor supervisors to higher odds for heart attack. If an inept or abrasive boss is ruining your workday, you may be taking that stress to heart, literally.
New research links having a poor supervisor to a higher risk of heart attack, and that's not all: people who don't like their managers also take more sick leave.
The findings, which come from surveys of thousands of employees in Europe, don't prove that bad bosses cause illness and heart problems, the report's author said.

Genes Linked to 'Pot' Belly
November 05, 2009
And excess consumption of saturated fats raises obesity risk, researchers find. New research sheds light on the possible link between the genes you inherit and the size of your belly.
Participants in a French study doubled their risk of having fat around the abdomen if they had a certain genetic trait, and the more of these traits one had, the greater the risk for a pot belly.
The study was looking at metabolic syndrome, a condition in which abdominal obesity, high cholesterol and high blood pressure combine to raise the risk of several diseases such as stroke, heart disease and type 2 diabetes.

Poorer Outcomes After 'Off-Pump' Bypass Surgery
November 04, 2009
Keeping patients on the heart-lung machine improved survival, study found. Longer-term outcomes for people who had coronary bypass surgery "off-pump," meaning without the use of a heart-lung machine, were worse than for those undergoing the conventional procedure, a major study finds.
One year after surgery, about one in 10 patients getting the off-pump procedure had died, suffered major complications, had heart attacks or required repeat bypasses, compared to 7.4 percent of those who underwent operations using heart-lung machines, researchers report in the Nov.

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.

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.

All New Dialysis Patients at Increased Risk of Death
October 27, 2009
Higher mortality rates not restricted to those with cardiovascular disease, study finds. A higher risk of cardiovascular-related death isn't the reason why kidney failure patients starting dialysis are at increased risk of death, according to new research that challenges previous thinking.
A number of studies have found that cardiovascular disease accounts for 40 percent to 50 percent of deaths in patients with end-stage kidney disease, and "it is believed that the life span of patients receiving dialysis is reduced mainly as a consequence of premature cardiovascular death," noted the authors of the new study.
Using data from between January 1994 and January 2007, the researchers compared the death rates in 123,407 dialysis patients in Europe and in the general European population.

Heart Disease Gender Gap Narrows
October 26, 2009
Middle-aged women have more heart attacks than in past, but are more likely to survive, studies show. Hearts attacks have increased among middle-aged American women in the past two decades, but their chance of survival has improved, two new studies show.
"We found that men still have a higher prevalence than women, but what has happened is that the gap has narrowed," said Dr. Amytis Towfighi, assistant professor of clinical neurology at the University of Southern California, lead author of one of two reports in the Oct.

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.

Big, Beefy Football Players May Face Heart Problems Later
October 26, 2009
Physical activity may not protect heart from complications of extra weight, study finds. Crushing the notion that you can be both fat and fit, new research has found that current professional football linemen already have some risk factors for heart disease.
In a study comparing professional football players to minor and major league baseball players, researchers found that football linemen were more likely to have higher fasting blood sugar levels, larger waist circumferences and a greater waist-to-height ratio.
Although the idea that a football player could be at risk for heart disease might seem paradoxical because football players have to be in top physical condition, the lineman position also requires players to bulk up, with many tipping the scales at more than 300 pounds.

Deaths also more common among those with chronic diseases, study finds. People who are super obese and those with the most chronic health problems face an increased risk for dying within a year after weight-loss surgery, a new U.S. study has found.
Blood Protein May Predict Heart Attack But Not Stroke
October 21, 2009
More study needed into how CRP levels influence risk. High blood levels of C-reactive protein (CRP) may increase a person's risk for heart attack and death, but not for stroke, a new study has found.
The study included 2,240 people in New York City who were 40 or older and stroke-free. At the start of the study, the participants' blood was checked for levels of CRP (a marker for inflammation) and their heart attack and stroke risk factors were evaluated by researchers.

Accelerated skeletal maturation may be early sign, researchers say.
New research links high blood pressure in children to bones that are more mature than average, suggesting that advanced bone age may predict cardiovascular problems.
The new study, published Oct. 19 in the journal Hypertension, looked at children and found that those without high blood pressure had bones that reflected their chronological age within four months.

Early Defibrillator After Heart Attack May Not Pay Off
October 07, 2009
European study finds no survival difference for those with, without device. Implanting a defibrillator in the first weeks after a heart attack does not improve survival, a major European study shows.
Fewer deaths from sudden cardiac arrest occurred among those given the devices, which shock the heart into beating again. But, the overall death rate was about the same as for those who did not get defibrillators in the 40 days after a heart attack, the researchers reported.

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.

Whether same will hold true for current H1N1 strain remains a mystery. People exposed to the deadly 1918 Spanish flu pandemic while still in their mother's womb were about 20 percent more likely to have heart disease 60 years later, a new study has found.
The flu outbreak in 1918 killed 20 million to 40 million people worldwide, including 500,000 in the United States. That flu, like the current H1N1 swine flu pandemic, began as a mild disease, but it then came back in a much more lethal form.

Fetal Surgery May Treat Heart Defect
September 29, 2009
Researchers see some success in alleviating hypoplastic left heart syndrome. Infants born with a rare heart defect may have better outcomes when surgery to repair the heart is done while the infant is still in the womb, Harvard University researchers say.
The condition, hypoplastic left heart syndrome, occurs when the fetus's left ventricle is underdeveloped and the heart cannot pump enough blood to sustain life. It affects about 1 in 10,000 newborns, and without open-heart surgery within a week of birth, these infants face death.

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.

Heart Patients Benefit From At-Home Care, Study Finds
September 28, 2009
Improvements seen in depression, quality of life for those with chronic heart failure. Patients with worsening chronic heart failure may find "hospital-at-home" care is a good alternative to treatment in a traditional hospital, Italian researchers report.
An estimated 5 million North Americans suffer from chronic heart failure, a condition in which the heart struggles to pump blood to the body. In the United States, worsening chronic heart failure is the cause of more than 1 million hospital admissions a year, and patients have a 50 percent risk of readmission within six months of discharge, according to the authors of a study published in the Sept.

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.

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.

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.

Any Day OK for Heart Bypass Surgery
September 23, 2009
Timing has no effect on outcome, study finds. There's no bad time of the day, week or year to have elective coronary artery bypass surgery, say researchers who analyzed how 18,597 people fared after having the procedure.
The Cleveland Clinic team conducted the study to determine whether working off-hours and long shifts might affect the performance of surgeons and other medical staff. Other studies have shown that lack of sleep, prolonged work hours and natural body-rhythm disturbances reduce the performance of drivers and pilots.

Hormone Therapy for Prostate Cancer Raises Heart Risks
September 22, 2009
Treatment methods should take into account side effects, researchers say. Hormone therapy to treat advanced prostate cancer can increase the risk of heart disease, but some types of hormone therapy appear to be safer than others, new research has found.
The study included 30,642 Swedish men with either locally advanced prostate cancer or prostate cancer that had spread (metastatic cancer), who had received hormone therapy as primary treatment for their cancer.
The study findings were scheduled to be presented Tuesday at the European Cancer Organization meeting in Berlin.

Flu Can Raise Chances of Heart Attack
September 22, 2009
Vaccine reduces risk of deaths related to heart disease, study shows. People suffering from the flu may be at higher risk for having a heart attack, especially those with heart disease and diabetes, British researchers report.
Because both seasonal and the pandemic H1N1 swine flu are circulating this fall and winter, people at risk for heart attacks are urged to get a seasonal flu shot and an H1N1 flu shot, which may reduce the chance of getting the flu and thereby lower the risk for a heart attack, experts say.
"Influenza is most concerning because of its secondary complications," said Dr.

Researchers Perfect the View of Heart Disease
September 18, 2009
CT technology could provide more detail at less cost, study suggests. Radiologists have developed a way to gain better insight into signs of heart disease by using cardiac CT scans that detect narrowed arteries and low blood flow.
CT scans use X-rays to create cross-sectional images of the body's internal anatomy. The scans can detect blockages in coronary arteries, but it's hard to tell if they're actually preventing blood from flowing to the heart.

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.

'Soda Tax' Wins Health Experts' Support
September 16, 2009
Researchers cite a win-win for health care and obesity, but beverage industry balks at proposal. A national tax of 1 cent per ounce of soda and other sugary drinks could stem the United States' obesity epidemic, while generating $14.9 billion the first year alone, health experts say.
That windfall could help finance proposed health care reform, while also funding programs to prevent obesity, say a group of prominent researchers in an article in the Sept.

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.

Celiac Disease May Raise Risk of Dying
September 15, 2009
People with with mild form of the digestive disorder have slightly higher death rate, study shows People with milder symptoms of celiac disease face a slightly higher risk of dying than other people, a new study finds.
Cancer and heart disease were the main causes of death in the patients studied, and the risk was higher in people who had had small-intestinal biopsies in childhood, the researchers found.
Celiac disease affects about 1 percent of people in the Western world, the researchers said, and it is triggered by exposure to gluten, a protein found in barley, wheat and rye.

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.

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.

U.S. Faces Shortage of Heart Surgeons
September 10, 2009
Too many aging Americans, too few new doctors spell trouble, experts say. The United States faces a dire shortage of cardiologists in the coming years, a shortage made even more critical given the increasing demands of a population rapidly growing older and heavier.
The shortfall could reach 16,000 cardiologists by 2050, according to a new report from the American College of Cardiology (ACC). As of right now, there are already 3,000 too few cardiologists in this country, the report finds.

Testing Young Athletes for Heart Defects May Save Lives
September 09, 2009
To prevent sudden cardiac death, researchers recommend electrocardiograms. Young athletes should be tested for heart abnormalities to prevent sudden cardiac death triggered by vigorous exercise, new Dutch research suggests.
Sudden cardiac death is the leading cause of death in young athletes, but no one knows how common it is, as figures vary and mandatory reporting does not exist, the study authors noted.
The idea of screening for potentially deadly heart abnormalities in athletes before they embark on a career in competitive sports has been debated for years.

Metabolic Syndrome May Raise Risk of Peripheral Artery Disease
September 09, 2009
Women much more likely to develop PAD if they had constellation of other symptoms, researchers found. Women with metabolic syndrome are at high risk of developing peripheral artery disease, a condition that dramatically raises the risk of heart disease and stroke.
Using data on more than 27,000 women taking part in the Women's Health Study, researchers identified participants with metabolic syndrome, a collection of symptoms including abdominal obesity, high blood pressure, low HDL ("good") cholesterol, high triglyceride levels and insulin resistance.
Women were considered to have metabolic syndrome if they had three or more of those symptoms.

Long-Term Lead Exposure Linked to Heart Deaths
September 08, 2009
Current OSHA guidelines are probably inadequate, researchers say. Exposure to lead over a lifetime may increase the risk of dying from heart disease, new research shows.
Researchers analyzed lead concentrations in the blood and bones of 868 mostly white men from the Boston area who participated in a veterans' aging study.
The men, whose average age was 67 at the start of the study, had lead concentrations in their blood and the bones of the patella (kneecap) and tibia (shin) measured over a nine-year period.

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.

Acupuncture May Help Relieve Polycystic Ovary Syndrome
September 04, 2009
Exercise also improves symptoms and related risk factors, study finds. Acupuncture and exercise may help women better handle the symptoms and risks that come with hormone imbalances caused by certain ovarian cysts, Swedish researchers report.
About one in 10 women of reproductive age have polycystic ovarian syndrome, a condition that can start in the teen years and cause irregular menstrual cycles and infertility. Small immature cysts on the ovaries disrupt hormone production, causing excessive secretion of testosterone, the male sex hormone.

Waist-Hip Ratio Good Gauge of Obesity in Elderly, Study Shows
September 04, 2009
After age 70, body mass index is less effective in identifying unhealthy weight levels, researchers say. Among the elderly, the ratio of waist size to hip size may be a better determinant of obesity than body mass index, say researchers from the University of California, Los Angeles.
For women between ages 70 and 80, every 0.1 increase in the waist-hip ratio was associated with a 28 percent increase in mortality rate, the research team reported.

Thin Thighs Might Be Harbinger of Heart Disease
September 04, 2009
Increased risk seen in Danish study, but authors say more research is needed. Thin thighs might look good in jeans, but a new Danish study indicates they might also raise the risk of premature death and heart disease in both men and women.
That's not to say fat thighs confer any survival benefit, the researchers stressed. Rather, the study of nearly 3,000 men and women who were followed for more than 12 years found the ideal thigh measurement was in the neighborhood of 60 centimeters, about 24 inches.

Statins Before Vascular Surgery Cut Deaths, Complications
September 02, 2009
Problems halved in patients getting blood-vessel repairs done, study finds. A dose of a cholesterol-lowering statin before vascular surgery reduces the risk of complications and death, new Dutch research shows.
The study of nearly 500 patients who had surgery for a variety of blood-vessel problems found the incidence of heart artery blockage and deaths was halved in those who received an 80-milligram dose of fluvastatin before their operation, compared to those given a placebo.
"The manuscript showed that fluvastatin extended-release is safe in the perioperative period, associated with a reduced inflammatory status and improved outcome, compared to placebo," said Dr.

Combo Therapies to Lower Cholesterol Don't Work
September 02, 2009
Review shows evidence doesn't support using other treatments with statins. Despite their popularity, so-called "combination therapies" may not be the most effective treatment for high cholesterol, Canadian researchers report.
In their review, the scientists analyzed data from 102 studies that tested combination therapies involving ezetimibe, niacin, bile acid sequestrants and omega-3 fatty acids. They concluded that there is little evidence to support the widespread use of combination therapies to lower cholesterol.

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.

Magazines that rank facilities don't take all measurements into account. Many hospitals don't make it onto the U.S. News & World Report list of best hospitals for heart disease but still perform well in some measurements regarding heart failure, researchers say.
Key Protein May Link Obesity, Diabetes, Heart Woes
September 01, 2009
Molecule in fat tissues spurs chronic inflammation that gives rise to disease, researchers say. Researchers say they know why obesity leads to diabetes and cardiovascular disease, a finding that may help experts target therapies to limit the health impact of being very overweight.
A Japanese team discovered a protein that causes ongoing, low-grade inflammation within fat tissues, which contributes to the health consequences that come with obesity, said Yuichi Oike of Kumamoto University in Japan.
The report appears in the Sept.

Reflux Drugs OK With Blood Thinners
September 01, 2009
Taking antacids with anti-clotting drugs doesn't change outcomes after a heart attack, researchers find. Antacids don't interfere with anti-clotting drugs such as Plavix and Effient in patients who have suffered a heart attack or unstable angina, a new study finds.
The results counter other studies that concluded that a class of antacids known as proton pump inhibitors (PPIs) could block the effect of anti-clotting drugs. Doctors often prescribe PPIs along with anti-clotting drugs to reduce the risk of gastrointestinal bleeding.

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.

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.

Hormone Therapy for Early Prostate Cancer Not Always Best
August 25, 2009
Study finds treatment raises death risk in those who also have heart disease. Men who have been diagnosed with prostate cancer and who also have underlying heart disease may not benefit from treatment with hormones, new research suggests.
In fact, such hormone therapy may actually increase their odds of dying.
"For men who've had a prior heart attack or heart failure, use of hormone therapy for prostate cancer was associated with a shortened lifespan," said study author Dr.

But factors other than gender may be to blame, researchers say. Women are more likely to die than men in the 30 days after a heart attack, but that doesn't mean gender is driving the trend, a new study finds.
Rather, "the difference can be attributed to well-known clinical and angiographic characteristics," such as age and the presence of other illnesses, said study lead author Dr. Jeffrey S.

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.

Glucose Challenge in Pregnancy Could Predict Heart Disease
August 24, 2009
Abnormal test results in those without gestational diabetes signals future heart risk, researcher says. A glucose challenge test given to pregnant women may also show if they have an increased risk of heart disease in the future, a new study has found.
This finding is important because doctors might be able to begin using current screening procedures for gestational diabetes to identify women who are at risk for developing heart disease later in life, the researchers said. Heart disease is the number-one killer of women in the United States and Canada.

Despite new technology and methods, experts say simple CPR works best. Medics and doctors are used to participating in a flurry of activity when trying to save a person who's had a cardiac arrest .
Medication Review May Help With Heart Failure
August 21, 2009
Hospitalizations decline when doctors, pharmacists collaborate, study finds. If doctors and pharmacists work together to ensure that people with heart failure take their medicines correctly, hospitalizations would be less frequent, an Australian study suggests.
In a study of 5,717 people with heart failure, the hospitalization rate for the 273 who had their medications reviewed by doctors and pharmacists was 45 percent lower than the hospitalization rate for the others, whose medicines did not undergo a collaborative review.
People in the study averaged about 82 years old.

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.

Stenting a Good Option for Left Main Heart Artery
August 19, 2009
As effective as standard of bypass surgery, Polish study finds. Twelve-year data on treatment of blockage of the left main heart artery indicate that using a drug-coated stent is an effective alternative to bypass surgery, doctors report.
The study of 314 people who underwent the procedure between 1997 and 2008 in Poland supports the findings of a large European trial, which found no difference in the death rate between bypass surgery and angioplasty for the condition, according to a report published online Aug. 19 and in an upcoming print issue of the Journal of the American College of Cardiology by a group of physicians from Poland and the United States.

Avandia Raises Heart Failure Risk More Than Actos
August 19, 2009
Diabetes drug shouldn't be used when there's a safer alternative, study says The type 2 diabetes drug Avandia (rosiglitazone) increases the risk of heart failure and death more than another drug in the same class, Actos (pioglitazone), new Canadian research contends.
Avandia has been the subject of controversy since 2007, when it was linked to an increased risk for heart attack and death, although those claims have become clouded as other studies have discounted that risk to some degree. But taken together, many believe that the drug should not be used, especially since there appears to be a safer choice.

Hospitals Reduce Heart Attack Deaths
August 18, 2009
Study shows 10-year effort, with major medical advances improved survival rates. A decade-long, government-led effort has reduced the death rate for patients hospitalized for heart attacks and improved the performance of hospitals that deal with these daily emergencies, a nationwide study finds.
Between 1995 and 2006, the in-hospital death rate for Medicare patients treated for heart attacks decreased, from 14.6 percent to 10.

Worries May Worsen Peripheral Arterial Disease
August 17, 2009
Distressed 'type D' personality associated with mortality risk, study suggests Having a negative, inhibited personality may increase the risk of death among people with peripheral arterial disease (PAD), a Dutch study suggests.
PAD occurs when plaque accumulates in arteries that supply blood to areas of the body other than the heart and brain.
The study included 184 PAD patients, average age 64.

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.

Cancer Deaths Declining, Especially Among Young
August 13, 2009
Advances in treatment, prevention and detection behind progress, study finds Cancer death rates are declining, especially among younger people, new research shows.
And while cancer is poised to become the number one killer in the United States, topping heart disease, that is because deaths from heart disease have decreased faster than for cancer.
"Older Americans have only experienced decreased [cancer] mortality very recently, but younger Americans have been seeing benefits for a long time so, as a result, everyone born in the last 60 years has been reaping the benefits of efforts in prevention research and treatment research and early detection research," said Dr.

Optimism Good for Heart and Longevity
August 10, 2009
Less cardiovascular disease, fewer deaths among the cheerful, study finds. Women who take a darker view of life are more likely to develop heart trouble than those with a cheerful, trusting outlook, a new study indicates.
The finding comes from the Women's Health Initiative, which has tracked more than 97,000 postmenopausal American women for more than eight years.
"In addition to looking at hormones and their effect on heart disease and cancer, the study also examined psychosocial and social factors and how they affected the health of postmenopausal women," said Dr.

Blows to the Chest Up Death Risk for Lacrosse Players
August 10, 2009
Injuries are fatal far more often than in other contact sports, study finds. Although sudden deaths occur in competitive lacrosse at about the same rate as in baseball and football, deaths caused by a strong blow to the chest are more common in lacrosse, new research shows.
Lacrosse has swept up about a half-million young participants in the United States, making it the fastest-growing youth sport in the country. The hard rubber balls used in the sport can travel as fast as 100 miles an hour, and contact also occurs between a lacrosse stick and an opponent's body, called a "body check.

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.

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.

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.

Vitamin D Deficiency Linked to Heart Risk Factors in Kids
August 03, 2009
Studies find many U.S. children not getting enough. Most American youngsters aren't getting enough vitamin D, and that deficiency is associated with an increased incidence of risk factors for cardiovascular problems such as heart attack and stroke, two new studies find.
Simultaneous publication of both papers in the Aug. 3 online edition of Pediatrics is coincidental, the lead authors of the reports said.

Response Times Vary for In-Hospital Heart Attacks
July 31, 2009
Uneven results seen when studying defibrillation delays in 200 locations, researchers say. Quick defibrillation can increase the chances of survival for hospital patients who have cardiac arrest, but sometimes the treatment is not quick enough and a new study has found that the delays are not due to overloaded or undereducated staff.
Defibrillation is a process in which an electronic device gives the heart an electric shock. This helps restore normal contraction rhythms in a heart having dangerous arrhythmia or in cardiac arrest.

More Kids Becoming Severely Obese
July 31, 2009
Expert urges additional programs, and coverage, for health effects. In the last 25 years, rates of severe childhood obesity in the United States have tripled, putting increasing numbers of children at risk for diabetes and heart disease, says a new study.
Researchers looked at National Health and Nutrition Survey data on 12,384 youths, ages 2 to 19 years, and found that the prevalence of severe obesity increased from 0.8 percent in the period from 1976 to 1980 to 3.

Blood Transfusions Not Linked to Long-Term Problems
July 31, 2009
No evidence that cancer cells or other health conditions are spread, study finds. Receiving a blood transfusion for low-risk cardiac surgery doesn't appear to increase one's chances of having long-term health problems, an Australian study has found.
In the study of 1,062 people who required a transfusion before, during or after the minor heart surgery, more than 80 percent of the patients were still alive a decade after the procedure, according to the results published in the August issue of Anesthesiology.
Previous studies had hinted that immune system problems, cancer and other major health issues could arise from blood transfusions.

Low-profile organ plays a big role in immune response, study finds Though its reputation doesn't rank down there with the appendix, the spleen isn't exactly known as a vital organ. In fact, plenty of people do fine without it.
But new research suggests the spleen plays a bigger role in the immune system than previously thought.

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.

Put Defibrillators in High-Traffic Spots, Studies Urge
July 29, 2009
Experts warn against politicizing their placement. Automated external defibrillators, or AEDs, can save the life of someone who is in cardiac arrest. So in what public spots should they be placed for maximum benefit?
In two new studies published online July 27 in Circulation, researchers focused on answering that question.
In cardiac arrest, the heart doesn't function, and without immediate cardiopulmonary resuscitation from someone, brain damage or death can occur in just four to six minutes.

Stent Studies Tied to Rapid Changes in Use
July 28, 2009
Fast dissemination of data may become main stimulus for change, experts say. Rapid dissemination of new data about the risks posed by drug-eluting stents led to an almost immediate decrease in the use of the stents, according to a new report.
Drug-eluting stents are coated with drugs meant to prevent re-narrowing of coronary arteries.
An analysis of patient registries showed that between January and September 2006, about 90 percent of people who had a type of heart attack called a non-ST-elevation myocardial infarction and underwent coronary stent implantation received drug-eluting stents.

Heart Surgeon Shortage Predicted
July 28, 2009
Trend toward stenting rather than bypass could be a cause, expert says. Over the next 15 years, there could be a severe shortage of cardiothoracic surgeons at a time when an aging population will probably increase the demand for surgical procedures that fall under their purview, a new study predicts.
The shortage could lead to diminished quality of care and delays in care for people needing heart and lung surgery, according to the study, which was done by the Center for Workforce Studies at the Association of American Medical Colleges.
By 2025, the researchers say, there could be a 46 percent increase in the demand for cardiothoracic surgeons, but a drop of at least 21 percent in the number of available surgeons.

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.

Giving Statins to Kids Provokes Debate
July 26, 2009
Cholesterol-lowering drugs may help young hearts, but long-term use raises concerns. Whether cholesterol-lowering drugs called statins should be given to children apparently depends on who you ask.
Major health associations in the United States have recommended that obese children as young as 8 years old be treated with statins if diet and lifestyle changes don't improve their health.
But the guidelines, issued by the American Academy of Pediatrics and the American Heart Association, have sparked debate in the medical community.

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.

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 .

Those who ate right, exercised lowered chances of cardiovascular trouble. All that heart-healthy advice about eating the right foods, exercising and losing weight pay off in real life for both men and women, two new studies show.
The reports, both originating at Brigham and Women's Hospital in Boston and published in the July 22/29 issue of the Journal of the American Medical Association, focused on different aspects of cardiovascular risk in two large groups: the 83,882 women in the second Nurses' Health Study, and the 20,900 men in the Physicians' Health Study I. Both arrived at the same conclusion: Do the right things, and you get measurable benefits.

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.

Vegetable Amino Acid Lowers Blood Pressure
July 08, 2009
Get plenty of it in your diet, researchers say. Researchers say they have discovered that one of the most common amino acids in vegetable protein seems to lower blood pressure.
Analysis of data from an international diet study shows that a 4.72 percent higher intake of glutamic acid as a portion of total dietary protein correlates with a 1.

Fewer Dying Now From Abdominal Aortic Aneurysms
July 06, 2009
Researchers credit better postoperative care for the improvement. In recent decades, long-term survival of patients who have surgery to repair intact abdominal aortic aneurysms has improved, a new study from Sweden finds.
The researchers also found that short-term survival has improved and long-term survival has remained stable for patients who have surgery to repair ruptured abdominal aortic aneurysms.
An abdominal aortic aneurysm is a bulge in the aorta (the main artery leading away from the heart) that occurs in the abdomen, the American Heart Association explained in a news release about the study.

On Memory, Older Americans Outsmart the English
July 03, 2009
Education, income and preventive health differences may explain results, study says. Older people in the United States scored better than their counterparts in England on a memory and awareness test, possibly because of differences in levels of depression and education and the fact that American adults receive more aggressive treatment for heart disease, a new study suggests.
The test assessed immediate and delayed recall of 10 common nouns, such as tree, skin, river, table, baby and village. The participants, 13,575 people all older than 65, listened to the words being spoken and then were asked to repeat as many as possible immediately and again five minutes later.

Increasing Alcohol Use Tied to More Hospitalization
July 02, 2009
Although heavy drinkers were affected most, link held for even mild drinking, study finds. The more alcohol men drink, the more time they spend in a hospital, research from the United Kingdom has found.
The study, which involved nearly 6,000 men in Scotland ages 35 to 64, began during the early 1970s. Initially, the men were given a comprehensive health examination and were asked about their alcohol consumption.

Master Stem Cell for Human Heart Identified
July 01, 2009
Researchers say it could hold the key to understanding the mechanics of the organ and how to repair it. For the first time, researchers have identified a single "master" stem cell in humans that is capable of differentiating into all three major cell types that make up the human heart.
"This is a very simple but very important and fundamental finding, and that is understanding how the human heart is built, how it is made, what are the progenitor cells which give rise to the human heart," said Dr. Kenneth Chien, head of the Harvard Stem Cell Institute's cardiovascular disease program and senior author of a paper in the July 2 issue of Nature.

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.

Study Supports Wider Use of Statins
July 01, 2009
Data shows reduction in heart attacks, strokes among those without established heart disease. An analysis of studies supports a growing belief that guidelines for prescribing cholesterol-lowering statin drugs should be expanded to include healthy people without established heart disease, cardiologists say.
The meta-analysis of 10 trials involving more than 70,000 participants found that statin therapy reduced overall mortality by 12 percent, major coronary events by 30 percent and strokes by 19 percent.
It supports the findings of the JUPITER trial, reported last year, which noted 54 percent fewer heart attacks and 48 percent fewer strokes among people taking a statin who had normal cholesterol levels but high levels of C-reactive protein, a marker of inflammation, said Dr.

Even After Death, Heart Attack Treatment May Not End
June 30, 2009
Too often, EMS crews feel obliged to bring unresponsive patient to hospital, study finds. Chances of surviving a heart attack that occurs outside of a hospital are slim, but paramedics often take people who have died to a hospital anyway because a variety of factors keep them from following recommended guidelines, a new study finds.
In the United States, paramedics treat almost 300,000 people with cardiac arrest each year. But despite what's portrayed on TV, fewer than 8 percent survive, according to the American Heart Association.

HIV Patients May Have Stiffer Arteries
June 26, 2009
But not significant enough to halt drug therapy, researchers say. HIV patients receiving highly active anti-retroviral therapy (HAART) are more likely to have a level of arterial stiffness similar to that in healthy patients with high blood pressure, a new study finds.
Arterial stiffness increases the risk of cardiovascular disease in people with high blood pressure.
The study provides new insight into the link between HIV infection, HAART use and the premature development of cardiovascular disease in HIV-infected patients, even when they have normal blood pressure.

New Heart Valve Repair System Tested for Safety
June 23, 2009
Reversible implant appears safe, but more study is needed, researchers say. A new method of repairing leaking mitral heart valves appears safe, a small study shows.
In the new study, researchers tested a reversible implant called the Percutaneous Transvenous Mitral Annuloplasty (PTMA) system, which is installed via a catheter.
In the heart, the mitral valve controls the flow of blood from the left atrium into the left ventricle (from the upper left chamber into the lower left chamber).

Electrocardiogram Blip Signals Heart Trouble
June 23, 2009
Greater risk of atrial fibrillation, need for pacemaker, early death, study shows. A slight abnormality in an electrocardiogram (EKG), until now thought to be insignificant, can be a warning sign of future cardiac problems and an increased risk of early death, a new study indicates.
Lengthening of what is called the PR interval, the right-hand portion of the jagged blip that records electrical activity as the heart contracts and expands, was associated with a doubled risk of developing the abnormal heartbeat called atrial fibrillation, three times the risk of needing a pacemaker, and one-and-a-half times the risk of early death, according to a report in the June 24 issue of the Journal of the American Medical Association.
"Historically, this has been viewed as benign," said study senior author Dr.

Little Steps Add Up to Major Reductions in Blood Pressure
June 16, 2009
Boosting patients' awareness lowers risk of stroke and heart trouble, study found. Small measures can turn high blood pressure around, and reduce the risk of heart attack, stroke and heart failure, finds a new study that examined efforts to boost patients' awareness of current and target blood pressure.
These measures can be as simple as carrying a blood-pressure wallet card to track clinic visits, document blood pressure and update medications, the researchers found.
The VA-Tennessee Valley Healthcare System distributed more than 30,000 blood pressure wallet cards to patients, aged 18 to 90.

Heart Association Warns of Surgery Risks in Obese
June 15, 2009
Complications may include wound infections, heart problems, new advisory says. Severely obese people undergoing surgery are at greater risk of heart problems, wound infections, prolonged hospital stays and other complications, according to a Scientific Advisory from the American Heart Association.
Yet many cardiologists, surgeons, anesthesiologists and other health-care providers underestimate the seriousness of the risks, particularly to the heart, the association warns.
About 3 to 4 percent of Americans are considered severely obese, defined as having a body mass index of 40 or higher, according to information in a news release from the association.

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.

Another Blood Fat Fuels Heart Attack Risk
June 09, 2009
Danish study fingers high levels of lipoprotein(a). Yet another type of blood fat may be linked to higher cardiac risk, a new study suggests.
A Danish study finds an increased risk of heart attacks in people whose genes give them high blood levels of a cholesterol-related blood fat, lipoprotein(a), but the researchers say more work is needed to justify treatment to reduce those levels.
"We show that those with the 10 percent highest lipoprotein(a) have a two- to threefold increased risk of myocardial infarction [heart attack], similar to that for the highest LDL cholesterol levels," said Dr.

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.

Age not a factor in treatment outcome, new study shows. Age shouldn't be a barrier to the use of coated stents, which appear to be safe and effective in heart patients aged 70 and older, say researchers who analyzed data on nearly 10,000 patients.
Stents are wire-mesh metal tubes inserted into an artery to keep it open.
In the new study, researchers in Boston found that elderly patients treated with these drug-coated stents had outcomes similar to younger patients, and that death rates among elderly patients with the paclitaxel-eluting stets were comparable to the general elderly population in the United States.

In athletes who stop menstruating, supplements boost vascular function, study finds. High-dose folic acid supplementation improved vascular function in young female runners who stopped menstruating (amenorrhea) because their caloric intake was lower than their energy output, researchers say.
The findings suggest that folic acid may decrease cardiovascular risk and also improve performance in young female athletes, according to the Medical College of Wisconsin researchers.
"Previous studies have shown that amenorrheic women runners have decreased dilation in the main (brachial) artery of the arm in response to blood flow.

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.

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.

Brain Can 'See' Objects Through Touch
May 28, 2009
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.

NFL Players Not at Increased Heart Risk
May 26, 2009
Study finds they showed no more signs of cardiovascular trouble than general male population. Those refrigerator-sized National Football League players you see on television every Sunday aren't at any higher risk of cardiovascular problems than the guy next door, a new study finds.
"Overall, the risk is similar to that of American males of similar age and race distribution," said Dr. Andrew M.

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.

Strict Blood Sugar Control Lowers Heart Risks in Diabetics
May 22, 2009
It prevents many complications of chronic disease, experts say.Diabetics who strictly control their blood sugar levels also reduce their risk of heart attack and cardiovascular disease, British researchers report.
There have been several conflicting reports about the value of dramatically reducing blood sugar levels in diabetic patients in preventing heart attack and heart disease. In fact, some have suggested that significantly lower blood sugar levels could possibly be harmful.

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.

With Heart Attacks, Fast Treatment Matters
May 20, 2009
The sooner angioplasty is done, the lower the death rate, study finds. People having a heart attack should be given balloon angioplasty without delay once they reach a hospital to reduce their risk of dying, a new study concludes.
Balloon angioplasty, or primary percutaneous intervention, is used to open blocked coronary arteries.
For the study, researchers analyzed data on 43,801 heart attack patients treated at U.

Higher Fitness Levels Tied to Lower Heart, Death Risks
May 19, 2009
Staying healthy means a quality life that lasts longer, review finds. Getting in shape really does help you live longer, new research says.
People with high levels of physical fitness, called cardiorespiratory fitness, have a lower risk of dying from all causes of death, including coronary heart disease and cardiovascular disease, than people with low levels of cardiorespiratory fitness.
Researchers analyzed data from 33 previous studies that included 102,980 participants and 6,910 deaths from a variety of causes and 84,323 people with coronary heart disease or cardiovascular disease and 4,485 deaths caused by those conditions.

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.

Daily Exercise at School Yields Rewards
May 14, 2009
Kids have healthier hearts and are less apt to be overweight, study finds.
. Daily exercise provides cardiovascular benefits even during the preteen years, reveals a new German study.
It found that schoolchildren, who averaged 11 years old, lowered their blood pressure, improved their levels of HDL ("good") cholesterol and triglycerides and were less likely to be obese if they regularly participated in a supervised exercise program that included at least 15 minutes of endurance training. The research was conducted in the city of Leipzig.

Catheter Ablation Effective in Treating Atrial Fibrillation
May 14, 2009
Burning faulty tissue better than meds for irregular heartbeat, study suggests Treating an irregular heartbeat by searing faulty heart tissue may be more effective than treating with medication, a new study shows.
Nearly two-thirds of study participants with atrial fibrillation experienced no such condition-related symptoms one year after having a catheter ablation, a procedure in which heart tissue responsible for the erratic electrical signals throwing off the organ's pumping rhythm is burned and destroyed. Only 17 percent of those in the study treated for the condition with medications reported being arrhythmia-free in the same period.

'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.

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.

Estrogen May Help Men's Hearts
May 12, 2009
Too much or too little of the hormone, though, can be damaging, study finds. Estrogen has long been implicated as being heart protective in premenopausal women, and a new study suggests that having just the right amount of estrogen might be helpful for men as well.
The study, in the May 13 issue of the Journal of the American Medical Association, found that men with heart failure who had the lowest levels of estrogen had about four times the risk of dying as men with average levels and that men with the highest levels of estrogen had more than twice the risk of dying as men with average levels of the hormone.
"Among men with chronic heart failure and reduced left-ventricular ejection fraction, high and low concentrations of estradiol [estrogen] compared with the middle quintile of estradiol are related to an increased mortality," the researchers wrote.

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.

Organ Donation Policies Vary Among Children's Hospitals
May 12, 2009
More research, better adherence to recommendations needed, study suggests. Children's hospitals have widely varying policies on organ donation after cardiac death (DCD), according to researchers, who asked 124 hospitals in the United States, Puerto Rico and Canada about their policies in 2007 and 2008.
The study authors received responses from 105 hospitals, and found that 72 percent of them had DCD policies, while policies were being developed in 19 percent, and 7 percent did not have and were not developing policies.
Of the 73 hospitals with DCD policies that were analyzed, 61 (84 percent) specified criteria or tests for declaring death, including electrocardiogram (ECG) findings, no pulse, no breathing, and unresponsiveness.

DASH Diet Has Extra Benefits for Women's Health
May 11, 2009
Diet to lower blood pressure may also cut risk of heart failure, research shows. A diet that prevents and lowers high blood pressure has been linked to a reduced risk of heart failure in women, a new study finds.
"The Dietary Approaches to Stop Hypertension [DASH] diet may contribute to prevention of heart failure in some cases because it effectively reduced blood pressure and low-density lipoprotein (LDL, or "bad") cholesterol levels in clinical trials," wrote Emily B. Levitan, of Beth Israel Deaconess Medical Center in Boston, and colleagues.

Racial Disparity Seen in Angioplasty Outcomes
May 08, 2009
Black patients more likely to experience complications, study finds. Black Americans are more likely than any other racial group to suffer serious complications after angioplasty and stenting and to require repeat procedures, but the reasons for these worse outcomes aren't clear.
That's the finding of a study that included 1,410 patients, average age 57, who had a percutaneous coronary intervention (PCI) procedure at Cook County Hospital in Chicago and were followed for an average of 1.7 years.

Fewer Heart Surgeries Needed as Technology Improves
May 08, 2009
Better prevention methods, medical advances likely behind drop in bypass procedures. Over the last decade, advances in heart surgery and improved heart disease prevention methods have resulted in a large decline in the number of patients in the United States having coronary artery bypass graft surgery, a new study finds.
Rates of bypass surgery steadily increased between the late 1980s and 1997, but have fallen by more than one-third since then. Open-chest surgery is increasingly being replaced by less invasive coronary interventions and being made unnecessary by advances in medications that fight the build-up of artery-clogging plaque, the researchers said.

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.

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.

Experts offer guidelines to help determine which patients need more observation. While some heart patients can safely go home after having elective angioplasty (also known as percutaneous coronary intervention, or PCI), others may have to stay in hospital for longer periods of time, says an expert consensus statement released Thursday.
The statement, published by the Society for Cardiovascular Angiography and Interventions (SCAI), notes that changes in reimbursement have put pressure on U.S.

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.

Drug-Coated Stents Better at Keeping Arteries Open
May 06, 2009
But they show no lifesaving benefit over bare-metal version, studies show. Although arteries propped open by drug-coated stents are less likely to become blocked again than those treated with bare-metal stents, the risk of death and heart attacks is virtually identical between the two devices, major studies in Sweden and the United States show.
The Swedish results eliminate concerns raised by an earlier study that the drug-coated stents might actually be more dangerous, said Dr. Stefan K.

CPAP Therapy Boosts Cardiac Surgery Outcomes
May 06, 2009
Findings suggest airway pressure treatment prevents complications, cuts readmissions. A few hours of postoperative treatment with continuous positive airway pressure (CPAP) may help improve outcomes in patients who've had heart surgery, finds a new study.
CPAP is commonly used to treat sleep apnea.
The study, published in the May issue of Chest, included 232 cardiac surgery patients who received standard postoperative treatment .

Irregular Heartbeat During Angioplasty Could Raise Death Risk
May 05, 2009
It tripled the 3-month odds among heart attack patients, study found. People treated for heart attack who experience abnormal heart rhythms during artery-opening procedures such as angioplasty may be at increased risk of death, a new study suggests.
The finding could challenge current cardiac care guidelines, experts say.
The study focused on patients who had heartbeat abnormalities called ventricular tachycardia or ventricular fibrillation when they underwent what is formally called a percutaneous coronary intervention (PCI) .

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.

Cholesterol Drugs May Help in Cardiac Emergency
May 01, 2009
A dose of a statin in time of crisis improved long-term outcomes, study found. Giving patients a cholesterol-busting statin drug during a coronary emergency can save lives and reduce the incidence of longer-term problems, Czech researchers say.
The one-year risk of death or major heart problems was more than halved for people suffering life-threatening episodes of acute coronary syndrome who received the drugs, compared to those who didn't, cardiologists at the Na Homolce Hospital in Prague reported at an American Heart Association meeting in Washington, D.C.

Genes May Affect Complications After Heart Surgery
April 30, 2009
Study finds more shock and kidney problems in those with variant. Testing for a gene variant that increases the risk of shock and kidney complications after heart surgery could help guide post-surgery treatment, say Australian and German researchers.
Currently, there are no effective medications to prevent these complications after heart surgery, according to background information in a news release from the American Society of Nephrology. When shock occurs, people are often given norepinephrine to stimulate their blood vessels and normalize their blood pressure, but not everyone metabolizes norepinephrine efficiently.

Clinics Less Likely to Refer Heart Patients to Cardiologists
April 28, 2009
Women especially affected if primary care came from community outlet. American heart patients who receive their primary care at a community health clinic are less likely to be referred for a consultation with a cardiologist than patients who receive their primary care at a hospital.
This difference is especially true among women, say researchers who reviewed the electronic medical records of 9,761 adult heart patients who received community clinic-based or hospital-based care between 2000 and 2005.
The overall rates for cardiology consultations were 79.

And prevents unnecessary testing, hospitalization, study shows. A computerized chest scan successfully singles out those people coming into emergency rooms with chest pains who have serious heart disease, a new study indicates.
Of the 368 people in the study, computed tomography angiography (CTA) was 100 percent effective in identifying the 31 who actually had acute coronary syndrome, according to a report in the April 28 issue of the Journal of the American College of Cardiology. None of the people who were cleared by the scans had a coronary event in the following six months.

Heart, Bone Problems May Follow Prostate Cancer Treatment
April 27, 2009
Men on hormone-lowering therapy may require close monitoring, researchers say. Though proven effective, treating prostate cancer with the testosterone-lowering treatment known as androgen deprivation therapy may raise men's risk for developing bone fractures and fatal cardiovascular disease, a new study suggests.
The likelihood of developing either side effect remains low, the researchers noted. But the study shines fresh light on the question of how best to weigh the potential benefits of androgen deprivation therapy (ADT) against the potentially serious complications that can ensue.

Hidden Salt in Diet Haunts Many With Heart Failure
April 25, 2009
Study finds high sodium intake, despite efforts to cut back. Eating a low-salt diet is one of the most important lifestyle changes people with heart failure can make, but only a third adhere to the recommendation, a new study has found.
Researchers asked 116 people with heart failure to write down everything they ate for three days. Though the recommended daily intake of sodium for people with heart failure is 2,000 milligrams, participants in the study were consuming an average of 2,671 mg a day.

Too Few Screened for Abdominal Aneurysm, Study Says
April 24, 2009
Potentially life-threatening condition often goes undetected until rupture. Few people who are at risk of an abdominal aortic aneurysm are getting preventive screenings, a new study has found.
An abdominal aortic aneurysm is a weak area in the main blood vessel that carries blood from the heart to the rest of the body. As blood passes through, the weakened area can bulge.

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.

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.

Abnormal Heartbeat After Bypass a Bad Sign
April 24, 2009
Atrial fibrillation ups long-term risk of dying, researchers report. People who develop the heartbeat abnormality called atrial fibrillation after heart bypass surgery are at increased long-term risk of dying, a new study finds.
The report sounds a warning bell for doctors about an issue that has not been a matter of major concern, said Giovanni Filardo, director of the department of epidemiology at the Baylor University Medical Center Institute for Health Care Research and Improvement. He was to present the findings Friday at an American Heart Association meeting in Washington, D.

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.

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.

Breast-feeding a Boon to Mom's Heart
April 21, 2009
Nursing baby brings cardiovascular benefits decades later, study suggests. Breast-feeding isn't just good for baby, it may also boost mom's cardiovascular health as she ages, new research suggests.
Women in their 60s who had breast-fed for more than 12 months over their lifespan were nearly 10 percent less likely to develop cardiovascular disease, and significantly less likely to develop heart disease risk factors, such as high blood pressure, diabetes and high cholesterol, researchers report.
"We found that the longer women breast-feed, the lower their risk of heart attacks, strokes or heart disease," said Dr.

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.

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.

Heart Screening Not Effective for Type 2 Diabetics
April 14, 2009
Imaging test doesn't single out those at high risk of trouble, study found. Routine screening for coronary artery disease is of no value for adults with diabetes who have no symptoms of heart problems, a new study finds.
Screening is expensive, at $1,000 per test. But the study of 1,123 people with type 2 diabetes who had no symptoms of heart disease did not identify those at high risk of developing cardiac problems.

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.

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.

Larger Men at Greater Risk for Atrial Fibrillation
April 08, 2009
Swedish study says since children are getting bigger, condition may become more common. Larger men are more likely to suffer atrial fibrillation (abnormal heart rhythms) than other men, according to Swedish researchers.
Beginning in 1970, the study surveyed more than 7,000 men aged 45 to 55, including questions about their lifestyle and their weight at age 20. That information was compared to data in Sweden's National Patient Register.

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.

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.

Statins May Help Before Artery-Opening Surgery
March 30, 2009
Italian studies report fewer heart attacks after procedures. Giving statins just before artery-opening angioplasty procedures reduces the incidence of heart attacks and other problems, even for people who already have been taking the cholesterol-lowering drugs, Italian trials show.
It's not the effect that statins have on cholesterol that is responsible for the benefits but rather their ability to reduce inflammation and other problems associated with heart disease, said Dr. Carlo Briguori, a cardiologist at the Clinica Mediterranea in Naples, who was to report the findings Monday at the American College of Cardiology annual meeting, in Orlando, Fla.

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).

One Pill Might Prevent Heart Disease
March 30, 2009
Study finds five drugs in one dose reduced heart attack, stroke risk. Create a single pill that contains a statin, three blood pressure drugs and aspirin, and you have an inexpensive medication that can reduce the risk of heart attack, stroke and other cardiovascular problems.
Or so researchers hope.
A first trial of the polypill (which already has a brand name, Polycap), has been successful, according to a report that was to be presented Monday at the American College of Cardiology annual meeting in Orlando, Fla.

No Increase in Clots With Drug-Eluting Stents
March 30, 2009
Risk appears the same for bare metal or drug-eluting devices, study found. Despite initial concerns that stent thrombosis, a blood clot inside a stent, is more common with the drug-eluting device, there appears to be no difference in the clot risk for either drug-eluting or bare metal stents, a large new study found.
After a heart attack, many patients undergo a treatment called angioplasty, which opens the blocked coronary artery that caused the attack. With many of these procedures, the stent, a metallic mesh tube that props open the narrowed artery, is also inserted and left in place.

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.

What Causes Mystery Heart Condition?
March 26, 2009
Stress cardiomyopathy linked to common drugs, study finds. The unusual heart syndrome called stress cardiomyopathy can be triggered by some commonly used heart medications, Johns Hopkins University researchers report.
Nine cases of the condition followed injections of adrenaline or dobutamine, according to a report in the March 25 online issue of the Journal of the American College of Cardiology.
Both dobutamine and adrenaline (which physicians prefer to call epinephrine) are used to increase the heart's ability to pump blood.

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.

Danon Disease Can Be Quickly Fatal, Study Finds
March 24, 2009
Heart experts stress the importance of genetic testing and diagnosis. A rare genetic heart disorder called Danon disease progresses rapidly and is often deadly in young people, according to a new study.
The recently recognized disease is a type of cardiomyopathy, or heart muscle disorder, linked to genetic mutations in the lysosome-associated membrane protein gene (LAMP2). Until now, the natural course of the disease was unclear.

Tight Blood Sugar Control May Raise Risks in the ICU
March 24, 2009
Very ill patients have higher mortality when glucose is too strictly controlled, study finds. People hospitalized in intensive care units, or ICUs, often experience spikes in blood sugar, and current practice is to try to lower these levels.
But a new study found that this strategy might actually boost the person's relative risk of death by 10 percent.
"Intensively lowering blood glucose in critically ill patients is not beneficial and may be harmful," said Dr.

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.

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.
Family History Plays Key Role in Blood Clot Risk
March 23, 2009
Study finds odds more than doubled, especially if kin was diagnosed at young age. Children and siblings of people who develop blood clots in the veins may be more than twice as likely as those without a family history to develop the condition, Dutch researchers report.
This kind of clot, known as a venous thrombosis, can be potentially dangerous, because it can break off and travel to the lungs.
The study authors compared 1,605 venous thrombosis patients with a control group of 2,159 people who never had the condition.

Study IDs Gene Variants Tied to Sudden Cardiac Death
March 23, 2009
Finding could prevent fatal arrhythmias by limiting meds in those with risk factor. Fourteen common genetic variants associated with a risk factor for sudden cardiac death have been identified by researchers who analyzed genetic data from more than 13,000 people.
The gene variants they identified influence the QT interval measured on electrocardiograms (EKGs) routinely used by doctors to assess patients' heart health. The QT interval is the time from the beginning of electrical activation of the heart to the end of electrical relaxation, according to background information in a news release about the study.

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.

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.

Millions of Americans With Chronic Ills Put Off Health Care
March 18, 2009
Survey shows they suffer consequences of delaying doctor visits, filling prescriptions. Millions of Americans suffering from at least one chronic health problem are putting off care, not taking needed medications, and resigning themselves to feelings of isolation and depression.
So reveals a new poll commissioned by the National Council on Aging, with support from The Atlantic Philanthropies and the California HealthCare Foundation.
"This report presents a distressing picture of the barriers facing those most in need of ongoing care and support, whether or not they have insurance," said Carol Pryor, policy director of the Access Project in Boston.

Obesity Takes Years Off Your Life
March 18, 2009
It's similar to smoking when it comes to effect on longevity, researchers note. Being obese can shorten your life, a new study shows.
"Moderate obesity typically shortens life span by about three years," said researcher Gary Whitlock, from the Clinical Trial Service Unit at the University of Oxford in the United Kingdom. "By moderate obesity, I mean weighing about a third more than is ideal, which for most people would mean being about 50 or 60 pounds overweight.

Drug Fails to Slow Progression of Atherosclerosis
March 17, 2009
Pactimibe also was associated with more risk of major heart problems, study finds. A drug that blocks an enzyme involved in the accumulation of cholesterol does not reduce the progression of atherosclerosis, thickening and stiffening of the arteries, but increases the risk of major cardiovascular events, according to an international study.
Researchers assessed the safety and efficacy of the drug pactimibe, which inhibits an enzyme known as ACAT, in 892 people with a family history of high cholesterol, which is associated with an increased risk of atherosclerosis. The participants, from 40 clinics in the United States, Canada, Europe, South Africa and Israel, were randomly selected to take either 100 milligrams a day of pactimibe or a placebo, in addition to standard lipid-lowering therapy.

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.

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.

Aging Baby Boomers May Swamp Cardiac Care
March 13, 2009
'Diabesity' renders them more prone to heart attacks than their predecessors, researchers say. Baby boomers are not in good shape, even when compared with their counterparts 10 or 20 years ago, researchers warn.
According to a new study, more aging boomers are being hospitalized for heart attacks now than people their age were a generation ago, and the increase in cases could place a big burden on cardiac care wards nationwide.
But on the upside, improvements in medical care may allow more people from this generation to recover and leave the hospital after a heart attack, the researchers say.

Drugs Before Stents for Stable Heart Disease, Study Says
March 13, 2009
Most important, expert says, is to aggressively try to reduce risk factors. Treating people with non-acute heart problems should start with drug therapy, not invasive techniques such as angioplasty or implanting stents, because there is no difference between the two approaches in outcomes, a new study finds.
There has been an ongoing debate over whether initial treatment of people with non-acute heart problems should be with drugs or whether it would be better to open blocked heart arteries with a catheter .

Cholesterol Drugs Linked to Increased Fatigue
March 12, 2009
Study shows a trend, but heart specialists remain skeptical. People prescribed widely used cholesterol-busting drugs called statins may be more likely to feel fatigued than those who don't, a new study finds.
But the findings don't prove that the medications make people tired, and heart specialists remain skeptical about the study, which focused on two statins, Pravachol and Zocor.
"There is not sufficient evidence that statins cause fatigue," said Dr.

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.

New Test Seems to Spot Deadly Heart Condition
March 11, 2009
Promises to make diagnosis simpler for disease than can strike younger adults. Researchers are reporting a promising new test for quick diagnosis of a rare but potentially deadly heart condition that is a leading cause of sudden death in young people.
The disease is arrhythmogenic right ventricular cardiomyopathy (ARVC), in which a genetic flaw causes the muscle cells of one of the heart's main pumping centers to be replaced by fatty deposits. The end result can be a sudden loss of regular heartbeat that is often fatal.

Breathing in smog heightens lung, heart risks, report finds. Thousands of Americans are dying each year from lung disease caused by atmospheric ozone, a new study finds.
The greatest risk may for those living be in hot, dry cities such as Los Angeles, which has one of the highest concentrations of ozone. Residents of Los Angeles may face a 25 percent to 30 percent higher annual risk of dying from a respiratory ailment versus people in low-ozone areas such as the Great Plains, the researchers said.

Slight Cut in Salt Intake Would Mean Fewer Heart Attacks, Deaths
March 11, 2009
Just 1 less gram a day could produce dramatic results, study says. If Americans cut just one gram of salt from their daily diet, there would be 250,000 fewer new cases of heart disease and more than 200,000 fewer deaths over a decade, a new study suggests.
And, though doctors have long known that too much salt is linked with high blood pressure and heart disease, Americans are using 50 percent more salt than they did in the 1970s .

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.

Belly Fat Puts the Pressure on Lungs
March 06, 2009
Obesity may affect diaphragm, chest wall to decrease volume, study says. Being big around the middle can put the squeeze on your lungs, according to French researchers who studied more than 120,000 people.
It was already known that abdominal obesity (waist circumference greater than 35 inches for women and greater than 40 inches for men) was associated with diabetes, hypertension, cardiovascular disease and numerous other health problems collectively known as metabolic syndrome.
This study found that abdominal obesity is also strongly associated with decreased lung function .

Blacks, Hispanics Less Apt to Get Best Heart Failure Care
March 06, 2009
Disparity exists even though more minorities than whites meet criteria for cutting-edge treatment. When black and Hispanic Medicare recipients suffer severe heart failure, they are less likely than their white counterparts to be treated with the most cutting-edge treatment available, a new analysis suggests.
"We found that there were real but modest differences between racial and ethnic groups in the use of the most advanced devices for the treatment of severe heart failure, even after considering all the medical and diagnostic factors when providing those treatments," explained the study's author, Dr. Steven A.

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.

Blood Thinner, Heartburn Drugs May Be Risky After Heart Attack
March 03, 2009
Patients taking Plavix, PPIs have 25 percent increased chance of death, rehospitalization. Heart attack patients given the blood thinner Plavix, plus a proton pump inhibitor such as Prilosec or Nexium, may be at increased risk of death or another heart attack, a new study finds.
Many patients are given Plavix (clopidogrel) to help reduce the risk of another heart attack after treatment for a first heart attack. Plavix makes blood platelets less sticky, helping to prevent clots from forming.
