Definition of Atherosclerosis
Medically reviewed by Min Clinic Staff | Updated: January 2026
Atherosclerosis: A process of progressive thickening and hardening of the walls of medium-sized and large arteries as a result of fat deposits on their inner lining.
Risk factors for atherosclerosis include high levels of "bad" cholesterol, high blood pressure (hypertension), smoking, diabetes and a genetic family history of atherosclerotic disease.
Atherosclerosis is responsible for much coronary artery disease (angina and heart attacks) and many strokes.
