Moreover, macrophages promote formation of complicated and unstable plaques by maintaining proinflammatory microenvironment. The Atherosclerosis Risk in Communities Study measured the direct effect of smoking on the development of atherosclerosis. Atherosclerosis begins at the adluminal surface, at the interface between blood and the arterial wall. This scheme places management of atherosclerosis in context of physiopathology, phase of disease, and intensity of risk (depicted by yellow to red gradient from right to left). Most symptoms of atherosclerosis don’t show up until one of your arteries is blocked. 8. These lesions may lead to narrowing due to the buildup of atheromatous plaque. Moreover, beyond atherosclerosis progression are questions relating to mechanisms of plaque regression and stabilization induced following marked LDL-cholesterol (LDL-C) reduction by lipid-lowering agents. Over time, plaque hardens and narrows your arteries. The term atherosclerosis is derived from the Greek "athero," meaning gruel, or wax, corresponding to the necrotic core area at the base of the atherosclerotic plaque, … A better understanding of the role of different lipoprotein particles in the formation of atherosclerotic plaques is now possible. The atheroma consists of a core of cholesterol joined to proteins with a fibrous intravascular covering. PVD, also known as arteriosclerosis obliterans, is primarily the result of atherosclerosis.
