急性心肌梗死急诊介入治疗中替罗非班冠状动脉内注入对疗效的影响

目的 观察急性心肌梗死患者急诊经皮冠状动脉介入治疗(PCI)术中冠状动脉内应用替罗非班的临床疗效.方法 76例急性心肌梗死患者随机分为替罗非班组(39例)和对照组(37例),均于发病12h内行急诊PCI.替罗非班组PCI术中冠状动脉内注入替罗非班,并静脉维持48h.术后应用达肝素钠注射液.对照组PCI术中仅给予普通肝素.两组PCI术前均服用氯吡格雷、阿司匹林.观察PCI术前、术后梗死相关血管心肌梗死时溶栓(TIMI)血流、心肌灌注分级(TMPG)、术后2周内并发症及主要心脏不良事件的发生情况.结果 替罗非班组PCI术后TIMI 3级占94.9%(37/39),高于对照组的78.4%(29/37),替罗非班组TMPG 3级占89.7%(35/39),高于对照组的67.6%(25/37),两组比较差异均有统计学意义(P值均<0.05).替罗非班组主要心脏不良事件的发生率7.7%(3/39)低于对照组的18.9%(7/37)(P<0.05),出血发生率与对照组比较差异无统计学意义(P>0.05).结论 PCI术中冠状动脉内应用替罗非班能改善急性心肌梗死患者梗死心肌的再灌注,减少术后主要心脏不良事件的发生率,且安全性好.

Effect of intracoronary tirofiban in patients undergoing primary percutaneous coronary intervention for acute myocardial infarction

Objective To investigate the efficacy of intracoronary tirofiban during percutaneous coronary intervention(PCI)for patients with acute myocardial infarction(AMI).Methods Seventy-six consecutive AMI patients,treated with primary coronary angioplasty in 12 hours were enrolled.They were randomly divided into two groups:tirofiban group(39 cases)and control group(37 cases).Tirofiban group was treated with intracoronary timfiban during PCI and after the operation for 48 hours.Both of them were given heparin in PCI and aspirin,clopidogrel before PCI.At the end of PCI procedure,angiographic features such as TIMI flow grade and TIMI myocardial perfusion grade(TMPG)were analyzed.The difference of two groups in complication and major adverse cardiac events(MACE) was investigated.Results The myocardial reperfusion of tirofiban group was better than that of control groupTIMI grade 3 flow 94.9%(37/39) vs 78.4%(29/37),P<0.05;TMPG 3 grade 89.7%(35/39)vs 67.6%(25/37),P<0.05].There was no significant difference between two groups in bleeding complication.The occurrence of MACE in tirofiban group was less than that in control group7.7%(3/39)vs 18.9%(7/37),P<0.05].Conclusion Intracoronary tirofiban dunng primary PCI in patients with AMI can improve coronary flow and myocardial perfusion,and has no more bleeding and less MACE occurrence.
