• Coronary atherosclerotic heart disease

This study aimed to explore correlations between haplotypes of the angiotensin II receptor type 1 (AGTR1) gene and coronary heart disease (CHD). In total, 204 patients with CHD and 206 healthy controls were genotyped using denaturing high-performance liquid chromatography between 2008 and 2014. Five polymorphic loci were found, namely, A-43281G, A-32954G, G-32839A, G-11064A, and A1880G. Likelihood estimates were used to identify haplotypes consisting of the A1166C locus and four of these five loci, then correlations between these haplotypes and CHD were assessed. Eight haplotypes with a frequency greater than 3% in the study population were discerned: ACCAA [ odds ratio (OR) = 1.2381, 95% confidence interval (CI) = 0.7726-1.9843]; ACCCA (OR = 1.2604, 95% CI = 0.6104-2.6027); ACTAA (OR = 0.8929, 95% CI = 0.6607-1.2067); ACTAG (OR = 0.9274, 95% CI = 0.5692-1.5110); ATTAA (OR = 1.0347, 95% CI = 0.7505-1.4265); ATTAG (OR = 0.9110, 95% CI = 0.4227-1.9631); GCCAA (OR = 1.1273, 95% CI = 0.7259-1.7506); and GCTAA (OR = 0.7981, 95% CI = 0.4379-1.4546). However, the frequency of these haplotypes did not significantly differ between CHD and the control groups. Thus, no correlation was established between the occurrence of CHD and AGTR1 haplotypes present at frequencies greater than 3%.
