In Russia, in recent decades, there were regional gapping in terms of social inequality and high level of morbidity and mortality in comparison with European countries. The high morbidity and mortality of population in the Russian Federation from diseases of circulatory system on one hand, and regional differences in terms of social economic status on the other hand, determined the purpose of the study. In order to evaluate relationship between social economic status of regions of the Russian Federation and incidence rate of myocardial infarction, the analysis was applied to standardized data of adult morbidity in classes of acute myocardial infarction and repeated myocardial infarction. Also was evaluated a number of social economic indices that reflect state and conditions of life of population. The statistical analysis was applied using MS Excel and Statistica 6 software. The critical significance level of null statistical hypothesis was established as p=0.05. When analyzing morbidity of adult population of Russia with acute and repeated myocardial infarction, significant regional differences were established. The seven factors were identified that statistically significantly affect morbidity rate of the adult population with myocardial infarction, which made it possible to divide the regions into four clusters, between which differences in morbidity rate of acute myocardial infarction were revealed. The analysis of morbidity of acute and repeated myocardial infarction established significant regional differences such as in 2017 7.7 times for acute myocardium infarction and 61 times for repeated myocardium infarction. The allocation of regional clusters depending on their social economic status allows to supplement regional and federal projects with risk-oriented technologies with purpose of decreasing morbidity of diseases of circulatory system.
