    Coronary Angioplasty

    Narrowed or blocked coronary artery

    Coronary arteries are the blood vessels that supply oxygen-rich blood to the heart muscle. The coronary arteries can get narrowed or blocked by the buildup of plaque. Plaque is made up of extra cholesterol, calcium, and other substances that float in blood. Over time, plaque can build up inside the walls of the coronary arteries. The buildup might reduce the blood flow to the heart muscle. During a heart attack, a blood clot could block blood flow in the artery. A procedure called angioplasty can widen a narrowed or blocked artery.
