(University of Western Ontario) Researchers at the University of Western Ontario have provided the first direct evidence using a biological marker, to show chronic stress plays an important role in heart attacks. Drs. Gideon Koren and Stan Van Uum developed a method to measure cortisol levels in hair providing an accurate assessment of stress levels in the months prior to an acute event such as a heart attack. The research is published online in the journal Stress. |
