atherosclerosis

atherosclerosis
Condition caused by the deposition of lipid in the wall of arteries in (atheromatous plaques). Migration of smooth muscle cells from media to intima, smooth muscle cell proliferation, the formation of foam cells and extensive deposition of extracellular matrix all contribute to the formation of the lesions that may ultimately occlude the vessel or, following loss of the endothelium, trigger the formation of thrombi. Should be distinguished from arteriosclerosis which is a more general term usually applied to arterial hardening through other causes. Atherosclerosis is a major medical problem in most of the developed world.
