Gene Mutation May Increase Chances of Heart Attack, Stroke

ABC News reports that a gene mutation may put people at higher risk of heart attack or stroke. Researchers at Duke University examined 6,000 patients with heart disease and found that those with this genetic mutation had a 38% increase risk of heart attack or stroke. Scientists believe that people with the mutation have a faulty serotonin receptor in the brain which stimulates the release of excess cortisol, the body’s stress hormone. In fact, “men with this gene mutation have been shown to have a two- to three-times larger cortisol response to stress,” which boosts the likelihood of an ischemic event. Experts note that this “research adds to the promise of more personalized, gene-centered medical care.”
