Aim: To study distribution of polymorphisms of angiotensin converting enzyme (ACE), angiotensin II type 1 receptor (AT1R), aldosterone synthase (CYP11B2) genes, and their association with processes of left ventricular remodeling in men of uzbek nationality with essential hypertension (EH).
Material and methods: Patients with stage 1-2 EH were genotyped for carrying I/D polymorphism of ACE gene, A1166C polymorphism of AT1R gene, and C(-344)T polymorphism of CYP11B2 gene. Echocardiography was used for measurement of left ventricular myocardial mass index.
Results and conclusions: Special features of distribution of studied genes among uzbek men were the following: accumulation of ID-genotype of I/D polymorphic marker of ACE gene among patients with EH, predominance of I-allele and II-genotype of ACE gene in healthy persons; accumulation of AA-genotype and A-allele of A1166C polymorphic marker of AT1R gene in patients with EH and healthy persons, while CC genotype was found only in patients with EH; predominance of CT genotype of C(-344)T polymorphic marker of CYP11B2 gene in patients with EH and healthy persons with high prevalence of T-allele in patients with EH. Carriage of TT genotype of C(-344)T polymorphic marker of CYP11B2 was associated with higher values of diastolic blood pressure. Associations were revealed between carriage of TT-genotype and T-allele of CYP11B2 gene, AC+CC-genotypes of AR1R gene and severity of left ventricular hypertrophy.
