摘要 目的探讨氯吡格雷弱代谢患者改服替格瑞洛的临床疗效及安全性。方法选取温州市中心医院心内科2014年2-12月期间住院行冠状动脉介入治疗术后存在氯吡格雷弱代谢的68例患者为研究对象,按照随机对照原则分为替格瑞洛组和氯吡格雷组,每组34例。替格瑞洛组给予替格瑞洛(90 mg,2次/d)治疗,氯吡格雷组给予氯吡格雷(150 mg,1次/d)治疗。治疗3 d后复查患者血栓弹力图,对血小板抑制率情况进行评价。随访半年,观察主要不良心血管事件及出血事件发生情况。结果治疗3 d后,替格瑞洛组患者二磷酸腺苷(ADP)抑制率(38.26%±12.47%)较治疗前(15.44%±3.80%)升高,血栓弹力图曲线的最大振幅(MAADP)(35.66±7.27)较治疗前(54.92±7.25)降低,差异均有统计学意义(P<0.05);治疗3 d后,氯吡格雷组ADP抑制率(16.82%±3.10%)和MAADP(53.08±3.05)均较治疗前(分别为16.24%±5.80%、52.12±2.47)无明显变化,差异均无统计学意义(P>0.05)。治疗3 d后,替格瑞洛组患者的ADP抑制率高于氯吡格雷组,MAADP低于氯吡格雷组,差异均有统计学意义(P<0.05);氯吡格雷组住院期间出现严重消化道大出血患者1例,出现支架内血栓1例,非致死性心肌梗死1例,不良事件发生率为8.82%;替格瑞洛组出现药物导致的呼吸困难、胸闷等症状1例,继而停药,不良事件发生率为2.94%。两组患者不良事件发生率比较,差异无统计学意义(P>0.05)。结论替格瑞洛应用于氯吡格雷弱代谢患者中起效迅速,抗血小板效果良好,严重并发症小,与氯吡格雷具有同样的安全性,值得在临床上推广。
