摘    要:目的探讨急性ST段抬高心肌梗死(STEMI)患者接受经皮冠状动脉介入术(PCI)治疗中,冠状动脉(冠脉)内应用血小板糖蛋白Ⅱb/IIIa(GPⅡb/Ⅲa)受体阻断药替罗非班对冠脉灌注、心肌灌注及临床预后的影响。方法连续入选87例发生急性STEMI并行急诊PCI的患者,入选患者随机分为冠脉内应用替罗非班组(冠脉组,n=45)与静脉内应用替罗非班组(静脉组,n=42)。冠脉组在支架释放后即刻在冠脉内3min注入替罗非班12μg/kg作为负荷量,随后以0.15μg/(kg·min)静脉维持24~48h;静脉组在支架释放后3min内静脉注入替罗非班12μg/kg作为负荷量,随后以0.15μg/(kg·min)静脉维持24~48h;术后随访3个月。比较两组患者PCI术后即刻梗死相关血管的TIMI血流分级(TFG)、校正的TIMI血流帧数计数(CTFC)、TIMI心肌灌注分级(TMPG)及心肌灌注显影分级(MBG);并比较两组PCI术后1周心脏超声指标、住院期间以及随访期间主要心脏不良事件发生率。结果 PCI术后即刻两组TFG、CTFC、TMPG、MBG均无显著差异(P均〉0.05),给予替罗非班冠脉内或静脉内给药后,两组TFG、CTFC、MBG、TMPG指标均较未给药前显著改善,冠脉给药组TFG、CTFC优于静脉给药组,差异有统计学意义(P〈0.05~0.01)。两组PCI术后1周心超结果(LVEF、LVEDD、LVESD)未见显著差异(P〉0.05);两组院内MACE事件发生率未达到统计学差异(P〉0.05),1月和3月随访期MACE发生率两组亦未见显著差异(P〉0.05)。结论 STEMI行急诊PCI治疗的患者,冠状动脉内应用替罗非班可显著地改善梗死相关血管的微循环血流,患者耐受性好,安全性高。

Abstract:Objective To investigate the influences of tirofiban(a blocker of intracoronary platelet glucoprotein receptor IIb/IIIa) on coronary perfusion,myocardial perfusion and clinical prognosis in the patients with acute ST-elevation myocardial infarction(STEMI) during percutaneous coronary intervention(PCI).Methods The patients(n=87) with acute STEMI undergoing emergency PCI were chosen and randomly divided into the group of intracoronary tirofiban(intracoronary group,n=45) and group of intravenous tirofiban(intr...
