NESFATIN-1 ACTIVITY IN THE BLOOD SERUM IN PATIENTS WITH CHRONIC HEART FAILURE OF ISCHEMIC ORIGIN AGAINST THE BACKGROUND OF TYPE 2 DIABETES MELLITUS AND OBESITY.

OBJECTIVE: The aim: To study the nesfatin-1 activity in the blood serum of patients with chronic heart failure (CHF) of ischemic origin against the background of such metabolic disorders as type 2 diabetes mellitus (T2DM) and obesity. PATIENTS AND METHODS: Materials and methods: 154 patients with CHF were examined, and divided into 4 groups, according to the presence of metabolic disorders. Group 1 included patients with CHF on the background of coronary heart disease (CHD) and T2DM and obesity (n=42). The second group consisted of patients with heart failure on the background of CHD with concomitant T2DM (n=46), the third group - with concomitant obesity (n=36), the fourth group was formed from patients with signs of heart failure of ischemic origin without metabolic disorders (n=30). The control group (CG) included 30 practically healthy persons of comparable age. RESULTS: Results: The mean level of serum nesfatin-1 was 1.64±0.27 ng/mL in the СHF group, 0.342±0.19 ng/mL in the CHF + T2DM + obesity group, 1.06±0.36 ng/ mL in the obese + CHF group, 0.96±0.27 ng/mL in the CHF + T2DM group and 2.98±0.38 ng/mL in the CG. Significant correlation was found between the serum nesfatin-1 level and BMI (r=-0.34, p<0.05), HOMA (r=-0.54, p<0.05), insulin (r=-0.41, p<0.05). No significant correlation was found between the serum nesfatin-1 level and blood glucose level (r=0.13, p=0.65). CONCLUSION: Conclusions: Thus, nesfatin-1 may play a significant role in the pathogenesis of both weight-related abnormalities and type 2 diabetes mellitus in patients with chronic heart failure of ischemic origin.

THE DYNAMICS OF NEUROHUMORAL MEDIATORS OF VASOCONSTRICTION AND VASODILATION AND TROPONIN I IN PATIENTS WITH ACUTE MYOCARDIAL INFARCTION DEPENDING ON THE DEGREE OF CONCOMITANT OBESITY.

OBJECTIVE: The aim: Is to evaluate copetin's, MRproADM's and troponin's I dynamic in patients with acute myocardial infarction depending on the degree of concomitant obesity. PATIENTS AND METHODS: Material and methods: The study included 105 patients with AMI. There were formed 2 groups: 1st group of patients with AMI and concomitant obesity (n=75), 2nd group - patients with AMI without obesity (n=30). 37 patients had obesity of the I degree, 38 patients - II degree. The groups were comparable in age and gender. Copeptin, MRproADM, troponin I were determined by enzyme immunoassay method. Data are presented as mean values and the error of the mean (M±m). Differences were considered statistically significant at p<0,05. RESULTS: Results: It was found an increased copeptin's level by 73,8 % (p<0,001) in obesity I degree and by 205,9 % in obesity II degree compared with group with isolated AMI, MRproADM - by 30,68 % (p<0,001) and 54,5 % (p<0,001) respectively. Concentration of copeptin was higher by 76 % (p<0,001) in patients with AMI and II degree obesity comparing to patients with obesity of I degree, and MRproADM - by 18,3% (p<0,001) respectively. Troponin I value fully corresponded the comparison group both in obesity of I degree and II degree (p>0,05). CONCLUSION: Conclusions: The present study provides evidence that a high activity of copeptin and MRproADM in patients with AMI and obesity of I degree with an excessive activity of a marker of vasoconstriction copeptin in conditions of moderate inadequate to the needs MRproADM functioning in patients with obesity of II degree.
