OBJECTIVE: An imbalance in sex hormone ratios has been identified in coronary heart disease (CHD), and as a key enzyme in the conversion of androgen to estrogen, aromatase plays an important role in the balance of sex hormone levels. However, there is a paucity of research into the potential roles of aromatase in CHD. In this study, we investigated associations between single-nucleotide polymorphisms (SNPs) in the CYP19 gene, which encodes aromatase, and CHD. METHODS: We collected 1706 blood samples from CHD patients and control participants and used propensity score matching techniques to match case and control groups with respect to confounding factors. In a final study population, including 596 individuals, we conducted a case-control study to identify associations between three SNPs in CYP19 and CHD using χ(2) or Fisher exact tests, and binary logistic regression analysis. Differences in lipid levels and parameters of echocardiography among individuals with different genotypes were assessed by one-way analysis of variance. RESULTS: The distributions of rs2289105 alleles in the CYP19 gene differed significantly between the CHD and control groups (p = 0.014), and the heterozygote CT genotype was associated with a significantly lower risk of CHD compared to the homozygous wild-type CC genotype (p = 0.0063 and odds ratio = 0.575). However, blood lipid levels and echocardiographic parameters among individuals with different genotypes did not differ between the CHD and control groups. CONCLUSIONS: The CT genotype of the rs2289105 polymorphism in the CYP19 gene is associated with a decreased risk of CHD and may be a genetic marker of protection from CHD.
