Coronary heart disease
A disease of the blood vessels of the heart that, if untreated, can cause heart attacks. Like any muscle, the heart needs a constant supply of oxygen and nutrients that are carried to it by the blood in the coronary arteries. When these arteries become narrowed or clogged by atherosclerosis and cannot supply enough blood to the heart, the result is coronary heart disease.
