Atherosclerosis, the narrowing and hardening of arteries created by the buildup of lipids, collagen, and smooth muscle cells, reduces arterial blood flow and results in decreased perfusion to body cells beyond the narrowed or hardened area. It is the loss of arterial elasticity occurring with arteriosclerosis that leads to conditions such as myocardial infarction, stroke, and peripheral vascular disease.
