[Lipids and atherosclerosis].
Atherosclerosis is a degenerative pathology of blood vessels leading to coronary heart disease, myocardial infarction and stroke. The basic lesion of atherosclerosis is the fibrous plaque, which consists of lipids, smooth muscle cells, macrophages and connective tissue matrix. Data derived from experimental and clinical studies indicate the crucial role of elevated serum LDL-cholesterol concentration in the formation of atherosclerotic lesions. HDL removes cholesterol from the arterial wall, stimulates arterial prostacyclin synthesis, inhibits adhesion molecules expression, has antioxidant properties and protects against atherosclerosis. Lipoprotein (a) competes with plasminogen for its binding site, leading to reduced fibrinolysis and is an important link between thrombogenesis and atherosclerosis. The pathogenic role of lipids in atherogenesis is discussed.
