Could the number of hours spent at work predict an individual's chance of developing coronary heart disease?One group of European researchers thinks it's a possibility.
Based on the group's findings, presented in the journal Annals of Internal Medicine, people who worked more than 11 hours per day had a 1.5-fold increased risk of developing coronary heart disease when compared to other subjects working seven to eight hours per day. Coronary heart disease, a condition that causes the blood vessels to the heart to narrow, is the leading cause of mortality in the United States. Other heart conditions such as angina and heart attacks contribute to the disease, according to the U.S. National Library of Medicine.
