Angina pectoris – commonly known as angina – is chest pain often due to ischemia of the heart muscle due in general to obstruction or spasm of the coronary arteries. The main cause of angina pectoris is improper contractivity of the heart muscle and coronary artery disease due to atherosclerosis of the arteries feeding the heart.
