Heart disease, specifically coronary artery disease (CAD), is the leading cause of death and disability among both men and women in the US. Reductions in blood supply due to narrowings of the arteries that supply the heart muscle with oxygen and nutrients (coronary arteries) result in chest pain and shortness of breath and may lead to permanent scarring of the heart muscle, as in the setting of a…
