Angina pectoris is the healthcare term for chest pain because of coronary heart disease. It appears when the coronary heart muscle doesn't get the amount of blood as it really needs. This commonly occurs due to the fact at least one of the heart's arteries is constricted or blocked. #AnginaPectoris
Angina occurs due to a block or spasm of the coronary arteries- the arteries that supply blood to the heart. As a result, the affected heart muscles are unable to get their necessary supply of oxygen and glucose in order to function adequately.
