Hair indicates heart attacks

A new study has found that a single strand of hair can help doctors predict a future heart attack.

High levels of the stress hormone cortisol in hair may be a strong predictor of heart attacks months in advance, said Canadian researchers in the journal Stress.

"Traditionally, cortisol has been measured in serum, urine, and saliva. All of these matrices measure cortisol levels in the last hours to days and, therefore, do not reflect the stress response over prolonged period of time," said study authors Stan Van Uum and Gideon Koren of the University of Western Ontario.
