The role of A2350G polymorphism in exon 17 of the ACE gene and A1166C - in 3'-UTR of the AGTR1 in the pathogenesis of left ventricular hypertrophy was studied in patients with essential hypertension (EH) and arterial hypertension combined with diabetes mellitus type 2 (AH + DM2). Patients with EH and AH + DM2 did not differ from the control sample of healthy individuals by allele or genotype frequencies. However, an association of both polymorphisms with LVH was detected in EH patients. The frequency of 1166C allele was higher in patients with LVH (33.6% vs 20.7% without LVH). A1166C polymorphism determined the magnitude of left ventricular mass index (LVMI) in EH patients as well (p = 0.007). 2350G allele frequency of the ACE gene was in 1.5, and GG genotype--in 3.5-fold higher in EH patients with LVH, as compared without LVH. LVMI was significantly higher in patients with GG genotype as compared with heterozygotes and AA homozygotes (p = 0.002). Thus the presence of 1166C allele of AGTR1 and 2350G allele of ACE can be considered as predisposing factors for LVH development in EH. In contrast, association of studied polymorphisms with presence or LVH degree was not detected in patients with arterial hypertension combined with DM2. This may indicate another structure of genetic component of predisposition to LVH in different causes.
