摘要 目的:比较不同负荷剂量的氯吡格雷在治疗急性冠脉综合症中的疗效与安全性。方法:收集就诊于我院诊断明确的急性冠脉综合症患者80例,随机分为两组,高剂量组40例在行在经皮冠脉介入治疗(PCI)术前给予600mg负荷剂量的氯吡格雷口服,然后150mg剂量维持7天;低剂量组40例在PCI术前给予300mg负荷剂量的氯吡格雷口服,然后75rag剂量维持30天,观察PCI术后支架血栓风险率、心肌梗死发作率、大出血率、死亡率。结果高剂量组使PCI术后支架血栓风险率下降31.0%、心肌梗死发作率降低35.1%、大出血率增加2.0%、死亡率无变化,与低剂量组相比较支架血栓风险率、心肌梗死发作率显著降低(P〈O.05)有统计学意义,大出血率、死亡率无显著变化(P〉O.05)无统计学意义。讨论高剂量的氯吡格雷可以显著降低PCI术后的心血管并发症,效果较低剂量显著,且无增加不良事件的风险。
