If you find yourself spending extra hours at work, take note: They may take a physical toll. A study released today in the journal Annals of Internal Medicine found that those who put in more than 11 hours a day at their jobs had a greater relative risk of coronary heart disease than those who worked fewer hours.
Researchers looked at data on 7,095 male and female full-time British civil servants ages 39 to 62 who had no evidence of coronary heart disease at the beginning of the study. During an average 12 years of follow-up, in which the participants were screened every five years for heart disease, 192 people suffered nonfatal heart attacks or coronary death.
