A meta-analysis on the association of genetic polymorphism of the angiotensin-converting enzyme and coronary artery disease in the chinese population

SUMMARY

OBJECTIVE:

To investigate the association between genotype insertion or deletion polymorphism of the angiotensin-converting enzyme gene (ACE) and susceptibility to coronary artery disease (CAD) in Chinese Han population.

METHODS:

We conducted a comprehensive search for the OR value of contrast between the group of genotype insertion or deletion polymorphism of the ACE and the group of CAD as an effective index. A meta-analysis (Stata 12.0) was used to test the heterogeneity of the results, combine the values for effect, conduct sensitivity analysis, and basic evaluation.

RESULTS:

A total of 638 studies were found on the association between polymorphisms of the angiotensin-converting enzyme gene and CAD, of which 44 studies met the inclusion criteria. In total, our study included 5619 cases and 4865 controls. The heterogeneity test of each study (P < 0.001) was carried out using a random effect model. The OR value of DD/ID+II was 1.95, 95% confidence interval (95%CI) (1.66-2.29). The OR value of II/DI+DD was 0.63, 95%CI (0.55-0.72). The funnel figure is basically symmetrical and the results of the sensitivity analysis were stable.

CONCLUSION:

The DD genotype of the angiotensin converting enzyme gene may be a weaker risk factor for CAD in the Chinese Han population.
