SUNDAY, November 14 ( — Women with very demanding jobs are nearly twice as likely to have a heart attack as their peers in more easygoing occupations, a new study suggests.

Researchers at Harvard Medical School analyzed 10 years of survey and medical data on more than 17,000 women in the health profession. The women, who were enrolled in a long-running study on , were all in their 50s or early 60s when the study began.

The women who said their job requires them to work "very hard” or “very fast” but who have little say over their day-to-day tasks—a combination known as "job strain"—were 88% more likely than those in less-stressful jobs to have a heart attack. They were also 43% more likely to need heart surgery, according to the study, which was presented today at an annual meeting of the American Heart Association (AHA) in Chicago.
