CHICAGO (AP) - A new study finds that job stress can take a toll on a woman's heart.
Researchers say women who have jobs with big demands but little authority are 40 percent more likely than women with less job strain to suffer a heart attack or a stroke or to have clogged arteries.
Worrying about losing a job can set the stage for heart problems, too.
Previous studies have focused on men, the traditional breadwinners. This is the longest major study of job stress in women, who make up nearly half of the workforce.
It involved 17,000 women who were studied for 10 years. Results were presented Sunday at a heart conference in Chicago.
