what are the other names for CAD?

ischemic heart disease IHD or coronary artery disease CHD

what disease does CAD include?

stable/unstable angina and MI

define atherosclerosis. how is it related to CAD?

a disease of the arteries characterized by the deposition of plaques of fatty material on their inner walls...CAD is caused by the narrowing of arteries by atherosclerosis

define chronic stable angina

chronic occurrence of chest discomfort due to transient myocardial ischemia with physical exertion or other conditions that increase oxygen demand

what can CAD cause?

chronic stable angina or acute coronary syndrome

unstable angina and MI, comes form the rupture of atherosclerosic plaque
