A decade-long study of 135,000 men found that those who did not have children had a higher risk of dying from heart disease than those who did, raising new questions over the links between fertility and overall health, U.S. researchers said on Monday.

A new, highly effective class of psoriasis drugs did not appear to raise the risk of heart problems in a review of published studies, but the analysis may not have been big enough to detect rare cases, U.S. researchers said.

Women who smoke cigarettes are more likely to develop heart disease than men who smoke, with the risk for women increasing every year that they smoke, according to a study.

Living alone after a heart attack is associated with a higher risk of death over the next four years, while a lack of support at home was also linked to a lower quality of life just one year after the attack, according to a study.

There's yet another reason for women to stay fit, eat healthy, abstain from smoking and maintain their weight at a healthy level: those who do so may be less likely to die from sudden cardiac death, a U.S. study said.

Women with heart disease who down a few cups of coffee each day tend to live as long as those who avoid the beverage, according to a study.

Many heart attack survivors fear that any form of exercise, including sex, could land them back in the hospital or worse, in the graveyard.

Scientists have found 13 new gene variants that increase a person's risk of developing heart disease, the world's number one killer, in a series of large-scale international genetic studies.

A greater percentage of people at high risk for heart disease keep up their exercise and diet programs when they get group telephone counseling, according to a study.

A medical study yesterday showed that the simultaneous use of two drugs can help one out of six people reduce their risk of major adverse cardiovascular events.
