The aim of the present study was to establish the role of HIF1A gene polymorphisms in the risk of developing premature coronary artery disease (CAD) in a well-characterized clinical cohort. Three polymorphisms in HIF1A (rs11549465, rs11549467, rs2057482) gene were genotyped in 949 patients with premature CAD, and 676 healthy controls (with negative calcium score by computed tomography). Under a dominant model adjusted for age, visceral to subcutaneous adipose tissue (VAT/SAT) ratio, hypertension, type 2 diabetes mellitus (T2DM), HDL-C levels, hypercholesterolemia and hypertriglyceridemia, the rs2057482 T allele was associated with decreased risk of premature CAD when compared to healthy controls (OR = 0.616, P(dom) = 0.020). The effect of the studied polymorphisms on various metabolic parameters and cardiovascular risk factors was explored. In this analysis, the rs2057482 T allele was associated with decreased risk of obesity, central obesity, hypertension, hypercholesterolemia, hypertriglyceridemia and increased risk of T2DM. Under a dominant model adjusted by age, the HIF1A rs2057482 T polymorphism was associated with high VAT/SAT ratio (P = 0.009) and HDL-C levels (P = 0.04) in healthy controls. The results suggest that HIF1A rs2057482 polymorphism is involved in the risk of developing CAD and is associated with some metabolic parameters and cardiovascular risk factors.
本研究旨在确定 HIF1A 基因多态性在明确临床队列中早发冠心病(CAD)发病风险中的作用。在 949 例早发 CAD 患者和 676 例健康对照者(计算机断层扫描提示无钙评分)中,对 HIF1A 基因的 3 个多态性(rs11549465、rs11549467、rs2057482)进行了基因分型。在调整年龄、内脏脂肪与皮下脂肪比值(VAT/SAT)、高血压、2 型糖尿病(T2DM)、高密度脂蛋白胆固醇(HDL-C)水平、高胆固醇血症和高三酰甘油血症的显性模型下,与健康对照组相比,rs2057482 T 等位基因与早发 CAD 风险降低相关(OR=0.616,P(显性)=0.020)。还探讨了研究多态性对各种代谢参数和心血管危险因素的影响。在该分析中,rs2057482 T 等位基因与肥胖、中心性肥胖、高血压、高胆固醇血症、高三酰甘油血症风险降低以及 T2DM 风险增加相关。在调整年龄的显性模型下,HIF1A rs2057482 多态性与健康对照组中高 VAT/SAT 比值(P=0.009)和 HDL-C 水平(P=0.04)相关。结果表明,HIF1A rs2057482 多态性与 CAD 发病风险相关,并与某些代谢参数和心血管危险因素相关。
