What is Angina?
Angina is a pain, tight feeling, heaviness, pressure or burning sensation usually felt across the chest. It may radiate to the arms, back, neck or jaw. It commonly occurs with exercise or emotional upset and resolves with rest.
The main cause of angina is narrowing of the coronary arteries, reducing blood supply and oxygen to the heart muscle. This is why angina often occurs when the heart needs more oxygen and the body is under stress. Coronary artery narrowing is usually due to deposits of fats and cholesterol in the arteries.
