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.
Symptoms of angina occur when the coronary arteries are narrowed or blocked by atherosclerosis or by a blood clot. The most common cause of angina is coronary artery disease. Angina pectoris is the medical term for this type of chest pain.
