Interplay between polymorphisms in the endothelial nitric oxide synthase (eNOS) gene and metabolic syndrome in determining the risk of ischemic stroke in Koreans

Abstract: Background: Endothelial nitric oxide synthase (eNOS) gene variants are known to play a role in atherosclerotic development. However, whether interplay between eNOS polymorphisms and metabolic syndrome (MetS) affects ischemic stroke (IS) risk has yet to be discovered. We investigated whether the combined effects of eNOS polymorphisms and MetS influence ischemic stroke risk in Koreans.Methods: We genotyped the eNOS −922A>G, −786T>C, 4a4b, and 894G>T polymorphisms in 531 IS cases and 502 controls using polymerase chain reaction-amplified DNA. We then investigated whether the presence of MetS and the number of MetS risk factors worked with eNOS polymorphisms to influence IS risk.Results: IS patients had a significantly higher prevalence of MetS than controls [adjusted odds ratio (AOR)=2.943, 95% confidence interval (CI), 2.256–3.840, P
