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

Abstract

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. 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: 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). 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.
