title: [Obesity and atherosclerosis].
abstract: The recent increase in the prevalence of obesity has significant contribution to development of atherosclerosis and consequent cardiovascular disease. Obesity especially visceral obesity causes insulin resistance and is associated with dyslipidemia, impaired glucose metabolism, and hypertension, all of which exacerbate atherosclerosis. One plausible mechanism proposed recently is that factors known as adipocytokines, produced by adipose tissue in obesity can directly impact the atherogenic environment of the vessel wall by regulating gene expression and function in endothelial, arterial smooth muscle, and macrophage cells. These include TNFalpha, leptin, adiponectin, resistin, MCP1 and PAIl as well as free fatty acids. Reduction of visceral fat mass leads to amelioration of these risk factors and potentially prevents cardiovascular events.
