For the First Time Proved That Stress is Followed by Heart Attack
September 6th 2010 -
U.S. scientists at the University of Western Ontario have demonstrated for the first time a direct link between chronic stress and heart attack. Using a biological marker, they measured the amount of the stress hormone cortisol, which had accumulated in the months before a heart attack in the hair shaft of the study participants.
In the investigation a total of 112 adult males were involved, 56 of which were due to a heart attack in hospital. In the hair of heart attack patients, the researchers found for the period of three months before the disease event a higher cortisol levels than in the hair of the comparison group. Regarding the known risk factors were diabetes, hypertension, smoking and familial predisposition, no significant difference between the MI and control group.
To measure stress, doctors determined the cortisol levels in blood serum, urine and saliva. These show only the current stress of the body and do not indicate the long-term course. The newly developed method enables to understand, to suffer as much stress a person had in recent months.
