Association of clinical and genetic factors with left ventricular hypertrophy in hypertension among the indigenous population Mountain Shoria

Abstract

Objective. To determine the association of clinical and genetic factors with the left ventricular hypertrophy among indigenous patients with hypertension living in Mountain Shoria.Design and methods. A clinical-epidemiological study of Mountain Shoria indigenous populations at isolated regions was undertaken. Continuous method surveyed 547 people, consisted of a sample of the adult population (18 years and older). Studied anthropometric data, lipid spectrum of the blood polymorphisms of genes ADRB1 (Ser49Gly, A/G, rs1801252) ADRA2B (I/D), ACE (I/D), eNOS (4a/4b) and MTHFR (C677T, Ala222Val, rs1801133) and their association with left ventricular hypertrophy.Results. The left ventricular hypertrophy in patients with hypertension was detected in 47.3% of the respondents. The odds ratio found among patients with hypertension duration of 5 years with the respondents hypertrophied myocardium 0.5 times lower (38.2%) than people without this disease of the heart - 61.8%, while among those with hypertension long history of more than 10 years, 4.1 times higher: 73.3% vs 26.7%. In a population of Shor hypercholesterolemia and giperbetaholesterinemiya associated with exaggerated myocardial damage. The percentage of smokers in a cohort of patients with hypertensive cardiac disease was (37.8%) and was higher by 2.0 times than in hypertensive patients without left ventricular hypertrophy (22.0%). With the relative risk of hypertension with myocardial damage in a population Shor associated gene ACE I allele. The odds ratio of hypertension to identify patients with cardiac respondents with heterozygous genotype AG ADRB1 gene was 3.0 times higher compared to the surveyed individuals with homozygous genotypes AA and GG.Conclusion. Among Shor risk of hypertension with left ventricular hypertrophy was influenced by factors: prolonged duration of the disease more than 10 years, smoking, hypercholesterolemia, giperbetaholesterinemiya. Installed Association II genotype of ACE gene and gene genotype AG ADRB1s development of left ventricular hypertrophy in patients with arterial hypertension in the population of Shor.
