摘要
目的对比研究经皮冠脉介入治疗(PCI)术前应用氯吡格雷常规负荷剂量(300mg)与高负荷剂量(600mg)对急性ST段抬高心肌梗死(STEMI)患者的近期疗效和安全性。方法 2006年8月至2008年2月的131例急性STEMI患者随机分为两组,其临床基本资料中,除年龄外,性别、基本用药等均无显著差异(P>0.05)。两组术前2h分别给予600mg(A组,n=65)和300mg(B组,n=66)负荷剂量氯吡格雷预治疗,之后均予75mg/d维持量。比较两组30d主要心血管事件(死亡、再发心肌梗死、紧急靶血管血运重建、心绞痛、脑卒中、再入院)、术后2hST段回落、术后心肌肌钙蛋白I(cTnI)峰值、30d出血事件和不良反应发生情况。结果两组PCI基线特征无明显差异。A组与B组比较,30d主要心血管事件〔7.7%(5/65)vs19.7%(13/66),P<0.05〕、术后2hST段回落〔70.8%(46/65)vs45.5%(30/66),P<0.05〕、术后cTnI峰值〔(15±3)μg/Lvs(22±5)μg/L,P<0.01〕差异有统计学意义;30d出血事件〔9.2%(6/65)vs7.6%(5/66),P>0.05〕和不良反应〔12.3%(8/65)vs10.6%(7/66),P>0.05〕差异无统计学意义。结论与常规负荷剂量(300mg)相比,高负荷剂量(600mg)氯吡格雷可显著改善急性STEMI行PCI患者的近期疗效,且安全性相似。
