Angina is a symptom of underlying coronary artery disease that is characterized by a fatty material called plaque that builds up over many years on the inner walls of the coronary arteries (the arteries that supply blood and oxygen to your heart). This build up limits the blood supply to the heart (as shown in the video below). Blood supply is specifically limited when the muscles of the heart have to work harder during exercise or when a person is under stress. {{#ev:youtube|GIWb4-a7A6A}}
