Cardiomyopathies (CMP) are considered diseases with unknown etiology. CMP are usually diagnosed on the late stages of the disease. It is an important task to seek methods which allow diagnosing CMP on the early stages of development. Aim – to estimate the type of polymorphic variants of angiotensin converting enzyme (ACE), glutathione S-transferase (GSTM1) frequency distribution among the CMP sick and healthy individuals living in the Republic of Bashkortostan, and to substantiate their role in the CMP pathogenesis. Material and Methods – There were 67 CMP sick put under observation. Out of them40 werediagnosed ischemic cardiomyopathy (ICM), and 27 were diagnosed dilated cardiomyopathy (DCM). The control group was made up of 110 practically healthy people. The results.In the ICM sick group the DD genotype (χ2=4.8; p=0.029) was definitely found more frequently, also in case of DCM the increase of DD genotype (χ2=4.0, p=0.044) frequency was ascertained. Conclusion – The genetic analysis of polymorphic locus of I/D ACE gene in the ICM and DCM sick showed decrease in frequency of occurrence II, ID genotypes, I allele and increase of D genotype and D allele which points out the increased risk of these cardiovascular diseases.
