Abstract

The metabolic syndrome has gone by several names over the past two decades. The diagnostic criteria were proposed by the ATP III of NCEP in 2001 and were accepted by European Society of Cardiology and European Society of Hypertension in 2003. The criteria (abnormal waist rate, HDL-cholesterol, triglyceride, blood pressure and fasting glucose) are listed and the presence of any three of these factors is considered sufficient for diagnosis. The prevalence of syndrome affects about a quarter of the Hungarian population with hypertension. The metabolic syndrome is associated with premature cardiovascular morbidity and mortality including an excess of sudden deaths. According to the recent literature data the main component of the syndrome, the obesity, especially with abdominal fat distribution is associated with hypertension, hyperinsulinemia and insulin resistance with related abnormalities of carbohydrate and lipid metabolism. The low HDL cholesterol, high triglyceride level and the small, dense LDL cholesterol particles are the parts of lipid component of syndrome. A variety of environmental (obesity, smoking, physical inactivity) and genetic factors (genetic mutations of lipoprotein lipase, hepatic lipase, CETP and PPA receptors) and the impaired FFA metabolism have all been related to lipid abnormalities. Sympathetic hyperfunction participates in the pathogenesis and complications of metabolic syndrome. Possible factors augmenting sympathetic activation include alterations of insulin, leptin, FFA, cytokines, sleep apnoe. Other important factors as the endocrin concept, the hypothalamus-hypophysis-adrenal axis, endothelial dysfunction are discussed. The impaired muscle insulin stimulated glycogen synthesis (FFA induced GLUT-4 inhibition) is the major cellular factor of insulin resistance. There is a continuous process from the insulin resistance state (with hyperinsulinemia) into the 2T diabetes mellitus (with hypoinsulinemia).
