摘要 目的 :探析CYP2C19基因多态性对PCI(经皮冠状动脉介入治疗)术后氯吡格雷反应性的影响。方法 :选取2016年4月至2017年7月期间在广州市番禺区中心医院进行PCI治疗的120例冠心病患者作为研究对象。根据PCI术后氯吡格雷反应性的差异将这些患者分为抵抗组(n=45)和非抵抗组(n=55)。提取两组患者的外周血基因组DNA,对其CYP2C19基因的多态性进行检测和对比。结果 :1)抵抗组患者的MPA高于非抵抗组患者(P<0.05)。两组患者的血小板计数、有硝酸酯类药物使用史的比率和有他汀类药物使用史的比率相比差异无统计学意义(P>0.05)。2)抵抗组患者CYP2C19*2基因突变的比率高于非抵抗组患者(P<0.05)。抵抗组患者CYP2C192*2等位基因G的频率低于非抵抗组患者,其CYP2C192*2等位基因A的频率高于非抵抗组患者(P<0.05)。3)两组患者CYP2C19*3基因突变的比率相比差异无统计学意义(P>0.05)。两组患者CYP2C192*3等位基因G和A的频率相比差异无统计学意义(P>0.05)。结论 :接受PCI术的冠心病患者其CYP2C19*2基因突变的比率与其术后发生氯吡格雷抵抗的可能性呈正相关。在对冠心病患者进行PCI术后对其CYP2C19基因的多态性进行检测可为其选择术后抗血栓治疗药物提供参考依据。
