摘要 目的:应用ST段回落指数观察加倍负荷剂量替罗非班对急性心肌梗死急诊介入治疗的有效性。方法:选择因急性ST段抬高心肌梗死(STEMI)入院,并接受直接急诊经皮冠状动脉介入(PCI)治疗患者98名,分为实验组(加倍负荷剂量替罗非班+PCI)48例和对照组(常规负荷剂量替罗非班+PCI)50例。观察两组术后心电图ST段回落指数,PCI术前、术后TIMI血流情况,30 d主要心血管事件(心绞痛,再次心肌梗死和死亡)。结果:实验组术后2、8 h心电图ST段回落指数高于对照组(P<0.05)。PCI术前梗死相关血管各级TIMI血流与对照组差异无统计学意义。实验组PCI术后即刻达TIMI 3级血流比例高于对照组(P<0.05),PCI术后30 min达到TIMI 3级血流比例显著高于对照组(P<0.05),实验组30 d内主要心血管事件(心绞痛+再次心肌梗死+死亡)的发生率较对照组降低70%(P<0.05)。结论:ST段回落指数能有效评价急性心肌梗死急诊经皮冠状动脉介入治疗后心肌损伤程度,是最简单易行的评估方法;加倍负荷剂量替罗非班在急性心肌梗死直接经皮冠状动脉介入治疗中改善术后心肌灌注,降低心血管事件发生率。
