Coronary artery disease (CAD), a multifactorial disease, is a common cause of mortality in humans. Polymorphisms in the endothelial nitric oxide synthase (eNOS) gene (-786T>C, 4a4b, and 894G>T) have been previously associated with increased CAD risk. However, the sample size of this previous study was too small and limited to comprehensively define an association between eNOS polymorphisms and CAD; therefore, this analysis was duplicated with a larger population. The study was conducted on 559 patients with CAD and 574 healthy controls.
Coronary artery disease
We studied the association between aldehyde dehydrogenase 2 (ALDH2) polymorphism and coronary artery disease (CAD) and clarified the mechanisms underlying this association. We searched the ISI, Medline (Ovid), PubMed, CNKI, Wanfang, and Weipu Databases. Statistical analysis was performed using Revman 5.0 and Stata12.0 softwares. A total of 3305 cases and 5016 controls in 12 case-control studies were included in this meta-analysis.
