Tropicality. Cardiomyopathies (CMP) are diseases of unknown etiology. CMP are usually diagnosed in late stages of the disease. The search for diagnostic methods for CMP in the early stage is of great importance. The purpose is to determine the character of distribution of polymorph genetic variations rates of angiotensin converting enzyme (ACE), glutathione S- transferase (GSTM 1) among CMP patients and healthy subjects living in the Republic of Bashkortostan and to substantiate their value in CMP pathogenesis. Materials and methods. A total of 67 patients with CMP were included in the study. Out of them, 40 patients were diagnosed with ischemic cardiomyopathy (ICMP) and 27 patients — dilatation cardiomyopathy (DCMP). 110 healthy persons were enrolled in the control group. Results. In the group of patients with ICMP, the genotype DD (x2=4,81; p=0,029) occurred more frequently. In DCMP group, there was also an increase in frequency of DD genotype of polymorph genetic locus of ACE gene (%2=4,046; p=0,044). Conclusion. Genetic analysis of polymorph l/D locus of ACE gene in patients with ICMP and DCMP showed a decrease in occurrence rates of II, ID genotypes, allele I, as well as an increase in DD genotypes and allele D. This is associated with an increased risk for the development of these cardiovascular diseases
