Chronic Stress is a Strong Risk Factor for Heart Attack, Study Shows


A case-control study published in Scientific Reports reveals that patients who suffered an acute myocardial infarction (AMI) had elevated cortisol concentrations in the month before the acute event.

Researchers measured cortisol levels in hair samples from 174 men and women who had been admitted for AMI to cardiology clinics in southeastern Sweden.

After controlling for established cardiovascular risk factors in a multivariate analysis, elevated cortisol levels were evident in both the men and women studied, showing that chronic stress is a strong risk factor for heart attack.
