替罗非班对急性心肌梗死急诊冠状动脉介入治疗作用的影响

目的探讨急性心肌梗死（AMI）行急诊冠状动脉介入（PCI）治疗中,应用替罗非班对冠状动脉血流、心脏标志物、血小板聚集率以及不良心血管事件（MACE）发生率的影响。方法回顾性分析AMI行PCI治疗的临床资料。一部分病例采取常规PCI治疗（对照组）,其他行常规PCI＋替罗非班治疗（观察组）。两组患者术前均给予阿司匹林及氯吡格雷口服,观察组术中给予替罗非班并维持至少24h,观察AMI溶栓试验（TIMI）2～3级血流获得率、TIMI心肌灌注分级（TMPG）2～3级获得率、实验室检查结果和术后6个月MACE的发生情况。结果观察组PCI术后TIMI3级血流获得率及TMPG2～3级血流获得率均高于对照组;术后24h观察组血小板聚集率、肌钙蛋白和肌酸肌酶同工酶（CK-MB）均明显低于对照组。随访6个月时,观察组MACE的发生率低于对照组。结论替罗非班可以改善PCI术后心肌血流,明显降低血小板聚集率,减少AMI急诊冠状动脉介入治疗术后心肌标记物的升高,减少患者术后MACE的发生率,且安全性好。

Clinical investigation of application of tirofiban in emergent PCI for AMI

Objective To explore the effects of tirofiban on coronary blood flow,cardiac marks(TNT-HSST,CK-MB),platelet aggregation rate and MACE in treatment of AMI by percutaneous coronary intervention(PCI).Methods The clinical data of the patients treated with emergent PCI were reviewed.Some of the cases received routine PCI(control group)and the others did routine PCI plus tirofiban(experimental group).Both groups of the patients were administered with aspirin and clopidogrel.Tirofiban was only used in experimental...
