Atherosclerosis of which vessels leads to coronary artery disease (CAD)?

Explanation:
CAD arises when plaque builds up in the coronary arteries, the vessels that supply the heart muscle. This atherosclerosis narrows those arteries and can limit blood flow, causing ischemia and the symptoms and risks of coronary artery disease. Stable angina is a symptom caused by this reduced flow, while myocardial infarction is a severe, acute event from a plaque rupture and blockage in a coronary artery. An aortic aneurysm involves the aorta, not the coronary arteries, so it does not describe the vascular change that leads to CAD.
