CORONARY ARTERY DISEASE
Coronary artery disease (CAD; also atherosclerotic heart disease) is the result of the accumulation of atheromatous plaques [this plaque is made up of fat , cholestrol etc.] within the walls of the coronary arteries that supply the myocardium (the muscle of the heart) with oxygen and nutrients,the filling up of the plaque in the lumen(free space in the artery for the flow of nutrients, oxygen etc.) of artery causes narrowing of lumen of the artery by decreasing its diameter. It is sometimes also called coronary heart disease (CHD).
