Methods The databases of PubMed, Web of Science, CNKI, Wan Fang Data, VIP and CBM were searched by computer. The related case-control study on the polymorphism of vitamin D receptor BsmI (rs1544410) and susceptibility to coronary heart disease From building to May 2016. Two researchers independently screened the literature, extracted data, and assessed the risk of being included in the study. Meta-analysis was performed using RevMan 5.3 software. Results A total of 7 case-control studies were included, including 2 182 coronary heart disease patients and 5 925 control subjects. Meta analysis showed that the BsmI (rs1544410) B allele and BB genotype in the general population were closely related to the prevalence of coronary heart disease [Bvs.b: OR = 1.36,95% CI (1.03,1.79), P = 0.03; BBvs.bb:OR=1.70,95%CI(1.06,2.72),P=0.03;BB+Bb vs.bb:OR=1.52,95%CI(1.00,2.30),P=0.05]. Subgroup analysis by age showed that BsmI (rs1544410) polymorphism was closely related to the prevalence of coronary heart disease in patients <65 years of age [Bvs.b: OR = 1.65,95% CI (1.00,2.73), P = BBvs.bb: OR = 2.64, 95% CI (1.12, 6.25), P = 0.03]; according to race The subgroup analysis showed that BsmI (rs1544410) polymorphism was closely related to the risk of coronary heart disease in Caucasians [Bvs.b: OR = 1.47,95% CI (1.10,1.97), P = 0.01; BB + Bb vs .bb: OR = 1.71, 95% CI (1.09, 2.68), P = 0.02; BBvs.Bb + bb: OR = 1.39, 95% CI (1.01, , 95% CI (1.10, 2.95), P = 0.02]. The subgroup analysis by gene test showed that the BsmI (rs1544410) polymorphism in TaqMan test was closely related to the prevalence of coronary heart disease [Bvs .b: OR = 2.18, 95% CI (1.06, 4.45), P = 0.03; BB + Bb vs. bb: 3.31, 95% CI (1.06,10.30), P = 0.04]. The subgroup analysis by case group showed that BsmI (rs1544410) polymorphism in ECG group was closely related to the risk of coronary heart disease [Bvs. b: OR = 1.15, 95% CI (1.02, 1.29), P = 0.02; BB + Bb vs. bb: OR = 1.22, 95% CI (1.02, 1.45) 0.03; BBvs.bb: OR = 1.31, 95% CI (1.03, 1.67), P = 0.03]. Conclusions The BsmI (rs1544410) B allele of the vitamin D receptor gene may increase the risk of coronary heart disease, especially in Caucasians and those <65 years of age.
