Polymorphism of ACE gene as the genetic predisposition of coronary artery disease in Eastern India

AimA case control study was designed to assess whether the prevalence of ACE gene polymorphism has any role in the development of CAD.MethodsThe study included unrelated 217 cases with CAD and 255 healthy controls. PCR was done using primers followed by agarose gel electrophoresis for study of different ACE gene polymorphisms. Multiple logistic regression analysis was carried out to find association between studied genotypes and lifestyle as well as biochemical risk factors.ResultsBoth DD [OR: 2.16; 95%CI: (60.60-67.40)] and ID [OR: 1.48; 95%CI: (93.28-97.72)] genotypes of the ACE gene showed significant associations in the development of CAD. Coexistence of diabetes and hypertension found to be risk modifier of the disease. Tobacco intake in various forms elevates the risk of the disease among the cases with risk genotypes.ConclusionID and DD genotypes of ACE gene came out to be predisposing factors for the CAD cases in our study population.
