Atherosclerotic cardiovascular diseases substantially have contributing to mortality and structure of disability in developed countries. Metabolic syndrome is a cluster of clinico-biochemical changes with the most aterogenic potential.Objective: to determine trends of early stages of metabolic syndrome and its relationship with the initial atherosclerosis in young and middle-aged men. Have been examined 436 men with an assessment symptoms of metabolic syndrome, as well as signs of subclinical atherosclerosis. The young men with initial manifestations of metabolic syndrome were characterized by the classical cardiovascular risk factors. According to the results of the study have been already diagnosed dyslipidemia, violation of apolipoproteides fractions, postprandial hyperglycemia at the initial stage of metabolic syndrome in this category of patients. have been proposed assessment of waist circumference, degree of diastolic blood pressure and postprandial glycemia as the most sensitive diagnostic markers of cardiovascular lesions in primary manifestations of metabolic syndrome.
