[Inflammation and atherosclerosis].
Atherosclerosis is a vascular pathology in which inflammation plays a major role at every stage of the disease. The inflammatory process develops in response to abnormal cholesterol deposits in the intima of large arteries. The inflammatory reaction is initiated by a phase of endothelial activation induced by cytokines, oxidized low density lipoprotein (LDL) and/or changes in endothelial shear stress. This leads to the primary expression of endothelial adhesion molecules and chemokines followed by the recruitment and activation of circulating monocytes and lymphocytes. The clinical manifestations of atherosclerosis, including acute coronary syndromes, are the consequences of atherosclerotic plaque rupture/erosion that triggers thrombus formation leading to the occlusion of the vessel lumen. The local inflammatory process at the level of the atherosclerotic plaque might influence the stability of the plaque through its potential effects on the extracellular matrix, and on the plaque thrombogenicity. In humans, systemic inflammation has been recognized as a major risk factor of occurrence of acute coronary syndromes.
