which term describes a fatty deposit on an artery wall?
Coronary artery disease (CAD) is the most common form of heart disease. In coronary artery disease, fatty deposits known as plaques collect on the inner wall of the blood vessels. Over time, the plaques thicken and arteries narrow (atherosclerosis), making it harder for the heart to pump blood throughout your body. Left untreated, atherosclerosis can lead to a heart attack.
