Coronary artery disease (CAD) is the leading cause of death of men and women in the United States.

CAD occurs when there is a hardening or narrowing of the arteries that supply the heart muscle. This occurs when there is a build-up of plaque or cholesterol on the inside of the arteries. Over time, the build-up can prevent blood from flowing through your arteries, resulting in lack of blood or oxygen to the heart muscle. When this occurs, you may experience chest pain (also known as angina) or a heart attack. Most heart attacks occur when a blood clot suddenly cuts off the heart's blood supply, causing permanent heart damage (National Heart, Lung, and Blood Institute).

Treatment options: stent, angioplasty, coronary artery bypass grafting, drug eluting stent, atherectomy, medical therapy.
