摘要 目的观察盐酸替罗非班对不稳定型心绞痛患者血小板α颗粒糖蛋白(CD62P)、血小板膜糖尿蛋白Ⅱb/Ⅲa复合物纤维蛋白原受体(PAC-1)的影响及安全性。方法观察住院拒绝行冠状动脉成形术的不稳定型心绞痛患者67例,分为替罗非班组34例和常规治疗组33例。入院后常规用药组服用阿司匹林300 mg/次,1次/d,服用3 d后改为阿司匹林100 mg/次,1次/d,氯吡格雷首日1次口服300 mg,以后75 mg/次,1次/d,低分子肝素5 000 U,2次/d,皮下注射,共3 d。替罗非班组除常规治疗组的措施外加用盐酸替罗非班,持续静脉滴注72h,起始负荷剂量为0.4μg/(kg.min),30 min,后0.1μg/(kg.min)持续静脉滴注,低分子肝素用量减半(2 500U)。并根据指南在没有禁忌证的情况下规应用他汀类、β受体阻滞剂及血管紧张素转化酶抑制剂类药物。观察用药前及3 d后血小板CD62P、PAC-1表达水平,30 d内心血管事件和出血并发症发生率。结果与治疗前比较,两组患者血小板CD62P及PAC-1表达水平显著下降(P<0.05);与常规治疗组比较,替罗非班组用药后3 d的血小板CD62P、PAC-1表达水平显著降低(P<0.05)。30 d内心血管终点事件发生率替罗非班组较常规治疗组显著降低(P<0.05),两组患者30 d内出血并发症发生率差异均无统计学意义(P>0.05)。结论替罗非班能有效抑制不稳定型心绞痛患者血小板活化,改善临床预后。
