The purpose of the study was to determine the frequency and nature of manifestations of left ventricular diastolic dysfunction in patients with non-alcoholic fatty liver disease with the background of metabolic syndrome (MS).Characteristics of patients and research methods: To solve this problem, 227 patients with MS (130 men and 97 women) were examined. The study was conducted in two phases. At the first stage, all patients with MS are divided into two groups: patients with NAFLD — 205 people and 22 — without liver damage. At the next stage, a group of NAFLD patients with left ventricular DD (n=136) (66.34%) (the main group) and patients with no DD (n=69) (33.66%) (the comparison group) were identified.Results of the study: the results of diagnostics, clinical and laboratory manifestations of left ventricular diastolic dysfunction in 136 patients with NAFLD on the background of metabolic syndrome are Presented. Significant factors of development and progression of diastolic dysfunction were identified, which include increased body weight and adipose tissue, insulin resistance, dyslipidemia, hyperuricemia, activity and stage of liver damage. According to the data of structural and functional changes in the myocardium, the role of diastolic dysfunction in the development of chronic heart failure in patients with NAFLD with manifestations of metabolic syndrome has been established.Conclusion: it was Found that the development of left ventricular diastolic dysfunction in patients with NAFLD is due to the morphofunctional state of the liver.
