　　That “Monday morning feeling” could be a crushing pain in the chest which leaves you sweating and gasping for breathe.Recent research from Germany and Italy shows that heart attacks are more common on Monday mornings and doctors blame the stress of returning to work after the weekend break.

　　The risk of having a heart attack on any given day should be one in seven, but a six-year study revealed that the average person had a 20 per cent higher chance of having a heart attack on a Monday than on any other day.Working Germans are particularly vulnerable(敏感的，脆弱的), with a 33 percent higher risk at the beginning of the working week. Non-workers, by comparison, appear to be no more at risk on a Monday than any other day. Another study of 11,000 Italians identified 8 am. on a Monday morning as the most stressful time for the heart. and both studies showed that Sunday is the least stressful day, with fewer heart attacks in both countries. The research also indicates that the Monday morning peak seems to be consistent from northern Germany to southern Italy in spite of the differences in diet and lifestyle.

　　The findings could lead to a better understanding of what triggers(觸發(fā)，激起)heart attacks, according to Dr. Stefan Willich. “We know a lot about long-term risk factors such as smoking and cholesterol(膽固醇)but we don’t know what actually triggers heart attacks, so we can't make specific recommendations about how to prevent them,” he said.However, he suggests that anyone who suffers from heart disease should take it easy on Monday mornings and leave potentially stressful meetings until midweek.
