THE INFLUENCE OF ATORVASTATIN ON OMENTIN-1 LEVEL AND INSULIN RESISTANCE IN PATIENTS WITH CORONARY ARTERY DISEASE AND OBESITY

Abstract

Adipose tissue is a powerful endocrine organ, which synthesizes significant amount of biologically active substances – adipokines. Due to adipokine dysfunction, a spectrum of diseases associated with obesity appears, namely, coronary artery disease, diabetes mellitus, hypertension and oncology. Hyperinsulinemia and insulin resistance play a significant role in pathogenesis of cardiometabolic complications in patients with obesity. They trigger a pathological cascade of reactions leading to cardiovascular diseases. Omentin-1 possesses anti-atherogenic action and it can modify peripheral effects of insulin. The aim of the study – to analyze changes in omentin-1 concentration and the condition of insulin resistance in patients with coronary artery disease and obesity during atorvastatin treatment. Materials and Methods. 55 patients with obesity were examined. They had general clinical examination; blood lipids, uric acid level and liver enzymes; glycated hemoglobin, glucose, insulin with the calculation of HOMA index and omentin-1 concentration was determined. Patients were divided into two groups: the group 1 – 20 patients with obesity, who did not suffer from CAD and did not take atorvastatin, and the group 2 – patients with CAD and obesity, who took atorvastatin. Determination of these indices was performed for patients of the group 2 in dynamics in 12 months. Results and Discussion. In the group of patients with CAD and obesity, who took atorvastatin, lipid levels were reliably lower, but levels of fasting glucose concentration, uric acid and liver enzymes were higher than in the patients who did not take the drug. Elevation of omentin-1 in blood serum was observed in 12 months in patients with CAD and obesity simultaneously with the increase in insulin level and the decrease in tissue sensitivity to it. Conclusions. Intake of atorvastatin by patients with coronary artery disease and obesity is accompanied by elevation of insulin concentration, intensification of insulin resistance and increase in omentin-1 level.
