Video: Cholesterol buildup in the arteries

Atherosclerosis refers to the narrowing of arteries caused by accumulation of fatty deposits, or plaques, and other substances. This happens when blood cholesterol enters the lining of the arteries and gradually builds up, forming fatty streaks. As cholesterol accumulates, raised lesions or plaques develop and blood flow decreases. This increases the risk of heart attack, stroke and other serious vascular problems.
