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 strangling pain in the chest which is caused by a poor supply of blood and oxygen to the heart. It is not a disease in itself but rather a symptom of other heart conditions. It is usually a symptom of coronary heart disease (CHD) although it can also be a symptom of coronary microvascular disease (MVD).
