Ⅴ．Reading Comprehension
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（触发，激起）heart attacks, according to Dr. Stefan Willich. “We know a
lot about long-term risk factors such as smoking and cholesterol（胆固醇）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 |
