In the setting of acute myocardial infarction, thrombolytic therapy fails to restore an adequate epicardial flow in a large number of patients. Although an increasing number of patients undergoes a percutaneous coronary intervention (PCI) after failed thrombolysis, this treatment has been poorly investigated. This review focuses particularly on the safety and prognostic impact of glycoprotein (GP) IIb/IIIa receptor inhibitors after failed thrombolysis. GPIIb/IIIa inhibitors have been demonstrated to improve the clinical outcome in patients undergoing primary PCI. However, the increased risk of bleeding with the administration of potent antiplatelet drugs after full-dose thrombolytics has limited the widespread use of GPIIb/IIIa inhibitors during rescue PCI. We recently reported that abciximab treatment during rescue PCI has a beneficial effect on the short-term prognosis, without excess bleeding complications. This result can be achieved by using the radial approach, a low-dose weight-adjusted heparin regimen, and by limiting the use of aortic counterpulsation. In conclusion, in case of thrombolysis failure, patients should be referred to tertiary hospitals where rescue PCI can be performed with expertise.
在急性心肌梗死的情况下,大量患者接受溶栓治疗后未能恢复足够的心外膜血流。尽管越来越多的患者在溶栓失败后接受经皮冠状动脉介入治疗(PCI),但这种治疗方法的研究还很少。本综述特别关注溶栓失败后糖蛋白(GP)IIb/IIIa受体抑制剂的安全性和预后影响。已证明GPIIb/IIIa抑制剂可改善接受直接PCI患者的临床结局。然而,在全剂量溶栓后使用强效抗血小板药物会增加出血风险,这限制了GPIIb/IIIa抑制剂在补救性PCI中的广泛应用。我们最近报告称,在补救性PCI期间使用阿昔单抗治疗对短期预后有有益影响,且无过多出血并发症。通过采用桡动脉途径、低剂量体重调整肝素方案以及限制使用主动脉反搏可以实现这一结果。总之,在溶栓失败的情况下,应将患者转诊至具备专业技术进行补救性PCI的三级医院。
