Ethnic differences in the association between angiotensin-converting enzyme gene insertion/deletion polymorphism and peripheral vascular disease: A meta-analysis.


ABSTRACT: Background:Several studies have investigated the association of angiotensin-converting enzyme (ACE) gene insertion/deletion (I/D) polymorphism with peripheral vascular disease (PVD); however, the results remain controversial. Therefore, we conducted the current meta-analysis to evaluate this relationship in the general population of different ethnicities. Methods:We searched PubMed, Embase, Web of Science, Wanfang Database, and CNKI to identify eligible studies. Random-effect models were applied to estimate the pooled odds ratio (OR) with a 95% confidence interval (CI), regardless of between-study heterogeneity. Results:A total of 13 studies with 1966 cases and 6129 controls were included in this meta-analysis. The pooled ORs for the association between ACE I/D polymorphism and PVD risk were not statistically significant in the overall population under all genetic models. In further ethnicity-stratified analyses, we found a statistically significant association of ACE I/D polymorphism with PVD susceptibility in Asians under most models. However, the association among Caucasians did not reach statistical significance. Conclusion:ACE I/D polymorphism might be associated with susceptibility to PVD in the Asian population, but there was no clear evidence indicating a similar significant relationship among Caucasians.
