Relationship between AGTrs2493132 polymorphism and the risk of coronary artery disease in patients with NAFLD in the Chinese Han population

Objective To investigate the relationship between angiotensin (AGT) rs2493132 gene polymorphism and the risk of developing non-alcoholic fatty liver disease (NAFLD) and coronary artery disease (CAD) in the Chinese Han population.Methods Polymerase chain reaction was performed to determine AGTgenotypes. Anthropometric and clinical data were investigated and statistically analyzed in the clinical laboratory department of Qingdao Municipal Hospital.Results The AGTrs2493132 CT + TT genotype was an important risk factor for CAD in patients with NAFLD and NAFLD + CAD in healthy controls. The AGTrs2493132 T allele increased the risk of NAFLD + CAD in healthy controls. The AGTrs2493132 CT + TT genotype and T allele also significantly increased the risk of CAD in patients with NAFLD after adjustments for age, sex, and body mass index. In addition, AGTrs2493132 T allele carriers showed higher total cholesterol (TC) and low-density lipoprotein (LDL) levels compared with non-carriers.Conclusions The AGTrs2493132 CT + TT genotype and T allele significantly increased the risk of developing CAD in patients with NAFLD in the Chinese Han population. The AGTrs2493132 T allele was associated with increased serum TC and LDL levels.
