<unk>  pectoris, commonly known as<unk> ,  is chest pain due to ischemia (a lack of blood and subsequent lack of oxygen supply) of the heart muscle. It is most often due to obstruction or spasm of the coronary arteries (the heart's blood vessels). Coronary artery disease, also referred to as atherosclerosis of the coronary arteries, is the most common cause of<unk> . The term derives from the Greek ankhon ("strangling") and the Latin pectus ("chest") meaning "a strangling feeling in the chest". In<unk>  pectoris, symptomatic onset may include chest discomfort indicated by a feeling of tightness, heaviness, or pain in the chest cavity.
