ObjectiveTo investigate the association between CYP11B2 gene polymorphism and left ventricular hypertrophy in Chinese hypertensive patients by the means of meta-analysis. MethodsLiteratures about case control study on the association of CYP11B2 gene polymorphism and left ventricular hypertrophy were searched from January 1980 to December 2012.The electronic databases searched included China national knowledge internet,Chinese biological medicine disk,Vip fulltext database,Wanfang fulltext database and Pubmed.Odds ratio (OR) of CYP11B2 genotype distributions in left ventricular hypertrophy (LVH) patients against NLVH patients were analyzed.RevMan 5.1 software was applied for investigating heterogeneity among individual studies and summarizing effects across studies by proper statistical methods. ResultsSix case-control studies were selected finally.A total of 1 791 hypertensive patients were included.The pooled OR (95% CI) of CC vs.TT+TC genotype was 1.21(0.80,1.81)(Z=0.91,P=0.36),the pooled OR (95% CI) of (TC+CC) vs.TT genotype was 1.16(0.68,1.98)(Z=0.54,P=0.59),and the pooled OR (95% CI) of C vs.T allele was 1.09(0.78,1.54)(Z=0.51,P=0.61). ConclusionThe genotype of CYP11B2 polymorphism is not associated with an increase risk of left ventricular hypertrophy in Chinese hypertensive patients.
