摘要 目的观察CYP2C19基因多态性与氯吡格雷抵抗(CR)的相关性并观察西洛他唑对CR患者的干预作用。方法对123例入选患者采用CYP2C19基因监测试剂盒进行CYP2C19基因监测,研究其基因分布,所有入选患者顿服300 mg氯吡格雷,采用光比浊法测定ADP诱导的血小板聚集率,对比服药后24 h血小板聚集率(PAR)的变化,研究CYP2C19基因的不同与CR的相关性。从CR患者中随机抽取40例平均分为A组及B组,A组加用西洛他唑治疗,B组继续氯吡格雷治疗,选用无CR的患者为对照组,观察三组患者服药后1 w PAR的变化。结果入选123例患者中,CYP2C19慢代谢型18例,中间代谢型66例,快代谢型39例。不同基因组CR发生率分别为44.44%(n=8),22.72%(n=15),17.94%(n=7)(P<0.05)。A组服药前基线PAR为68.6%±6.2%,服用西洛他唑后PAR为41.1%±3.4%,服药前后比较差异有统计学意义(P<0.01)。B组服药1 w前后PAR比较无统计学意义(P>0.05)。C组治疗前后PAR明显降低(P<0.05)。结论冠心病患者CYP2C19基因从快代谢型到慢代谢型,CR的发生率明显升高,两者有很好的相关性,西洛他唑对CR有明显的改善作用。
