Hair's Cortisol Content Strong Predictor of Future Heart Attack

RoseTracker| To date, erectile dysfunction has been one of the strongest predictors of a future heart attak in men. Researchers now have a new tool: cortisol levels in men’s hair (and presumably women, too, although only men comprised the study.)

Doctors at The University of Western Ontario determined that different levels of cortisol, the human stress hormone, are revealed in strands of hair growth. By comparing the hair samples of 56 men who suffered heart attacks, compared to 56 men who didn’t have heart disease, researchers observed progressively higher cortisol levels in the heart attack patients.

After accounting for all the known risk factors among the study participants, a progression of increasing cortisol levels in a man’s hair emerged as the strongest predictor of heart attack in this small, but very important, study. via Science Daily.
