Exertional angina, or stable angina, is a type of chest pain caused by the blockage of blood flow through a coronary artery, or blood vessel around the heart.
Angina is a pain that comes from the heart. It is usually caused by narrowing of the coronary arteries. This narrowing causes a reduced blood supply to part, or parts, of the heart muscle. The narrowing is caused by fatty patches or plaques (atheroma) which develop within the inside lining of arteries.
