Coronary artery disease - Definition


Coronary artery disease is a condition that is due to a lack of oxygenation to the heart. This condition occurs in case of decreased vascularization of the heart resulting from a problem in the coronary arteries. Coronary heart disease can be due either to an arterial lesion or to sediment as in the case of atherosclerosis, a progressive closure due to the excessive presence of cholesterol, or following a heart attack by migration of a stone which abruptly blocks a coronary and causes the death of certain cells of the myocardium. Diseases which may appear in cases of coronary heart disease are myocardial infarction, or heart failure.
