This study sought to explore the relationship between cytochrome P450 2C19 (CYP2C19) *2/*3 polymorphisms and the development of coronary heart disease (CHD), and to evaluate the influence of the single nucleotide polymorphisms (SNPs) on the occurrence of adverse clinical events in CHD patients. A total of 231 consecutive patients candidate for percutaneous coronary intervention genotyped for CYP2C19*2 (681G>A) and *3 (636G>A) polymorphisms were enrolled. The adverse clinical events were recorded during a follow-up period of 14 months. The incidence of CHD, according to coronary angiography, was significantly higher (P=0.025) in CYP2C19*2 carriers group. Stepwise binary logistic regression analysis revealed that among factors that potentially influenced the presence of CHD (age>60 years, gender, BMI, etc.), CYP2C19*2 carriers (OR 1.94, 95% CI: 1.08–3.50, P=0.028) and male gender (OR 2.74, 95% CI: 1.58–4.76, P=0.001) were independent predictors, which were associated with the presence of CHD. The follow-up results showed that the incidence of adverse cardiovascular events within 14 months of discharge was significantly higher in the CYP2C19*2 carriers than in the non-carriers (21.6% vs. 6.3%, P=0.019). The results of the multivariate Cox proportional hazards model showed that CYP2C19*2 loss-of-function was the only independent factor which predicted the coronary events during the follow-up period of 14 months (OR=3.65, 95% CI 1.09–12.25, P=0.036). The adverse impact of CYP2C19*2 polymorphisms was found not only in the risk of the presence of CHD, but also in the adverse cardiovascular events in CHD patients during the follow-up period of 14 months. However the same influence was not found in CYP2C19*3 mutation in Chinese Han population.
