Cardiovascular evaluation, including resting and exercise electrocardiography, before participation in competitive sports: cross sectional study

Nearly half of patients with a history of heart disease have poor knowledge about the symptoms of a heart attack and do not perceive themselves to have an elevated cardiovascular risk, according to a report in the May 26 issue of Archives of Internal Medicine, one of the JAMA/Archives journals.

About 40 percent of African-Americans have a genetic variant that can protect them after heart failure and prolong their lives, according to research conducted at Washington University School of Medicine in St. Louis and collaborating institutions.

Scientist John Incardona will tell a scientific detective story that uncovers a previously unrecognized threat to human health from a ubiquitous class of air pollutants.

A new study shows that more women under 45 are dying of heart disease due to clogged arteries, and the death rate for men that age has leveled off.

If you think you can lower the risk of heart disease by cutting down on salt, you're wrong, as a new study has found no conclusive proof of any link between having salt and the incidence of heart disease.

The prevalence of asymptomatic peripheral artery disease (PAD) is steadily increasing among American adults, researchers reported at the American Heart Association’s Scientific Sessions 2007.

The genetic family ties that bind brothers and sisters also link their risk for developing clogged arteries and having potentially fatal heart attacks, scientists at Johns Hopkins report. And according to researchers, brothers bear the brunt of the burden.

Late-breaking results from the ENDEAVOR IV trial, presented at TCT 2007, the annual scientific symposium of the Cardiovascular Research Foundation, show that the Endeavor zotarolimus-eluting stent met the trial’s primary endpoint, demonstrating a similar overall safety profile (equivalent rates of death, heart attack, and repeat procedures) to the Taxus paclitaxel-eluting stent at 1 year.

Scientists report that the concentration of a compound called apolipoprotein B in the blood is better at predicting whether Chinese have coronary heart disease – in which fatty deposits clog arteries that supply blood and oxygen to the heart – than other substances such as blood cholesterol levels.

The World Heart Federation says heart disease and stroke are the world's largest killers, claiming 17.5 million lives a year. Marking World Heart Day, the Federation says knowing the risk factors and leading a healthy active lifestyle can largely prevent people from getting these chronic, ultimately fatal diseases.

Doctors said Monday that women with heart problems may need to be treated differently than men. Research presented at the annual European Society of Cardiology meeting in Vienna suggested that surgeries that typically save men's lives can actually be deadly for women.
