The CYP2C19*2 loss-of-function allele is associated with reduced generation of active metabolites of clopidogrel. However, meta-analyses have supported or discounted the impact of genotype on adverse cardiovascular outcomes during clopidogrel therapy, depending on studies included in the analysis. Here we review these data and conclude that evidence supports a differential effect of genotype on protection from major adverse cardiovascular outcomes following percutaneous coronary intervention (PCI), but not for other clopidogrel indications.
CYP2C19*2 失活等位基因与氯吡格雷活性代谢物生成减少有关。然而,荟萃分析支持或否定了基因型对氯吡格雷治疗期间不良心血管结局的影响,具体取决于分析中纳入的研究。在此,我们对这些数据进行了回顾,得出的结论是,有证据表明基因型对经皮冠状动脉介入治疗(PCI)后主要不良心血管结局的保护作用存在差异,但对氯吡格雷的其他适应证则没有。
