Angina pectoris

Angina pectoris – commonly known as angina – is chest pain due to ischemia of the heart muscle, generally due to obstruction or spasm of the coronary arteries.[1] The main cause of Angina pectoris is coronary artery disease, due to atherosclerosis of the arteries feeding the heart. The term derives from the Latin angina ("infection of the throat") from the Greek ἀγχόνη ankhonē ("strangling"), and the Latin pectus ("chest"), and can therefore be translated as "a strangling feeling in the chest".
