Primary percutaneous coronary intervention (PCI) has been demonstrated to be superior to fibrinolytic therapy in reducing mortality in ST-segment elevation myocardial infarction (STEMI) when it can be performed rapidly. However, many STEMI patients present to hospitals without PCI capability and often cannot undergo PCI within the guideline-recommended timelines; instead, they receive fibrinolysis as the initial reperfusion therapy. Several studies have explored the potential of combining the best of both therapies by performing PCI soon after fibrinolysis, including TRANSFER-AMI (Trial of Routine Angioplasty and stenting after Fibrinolysis to Enhance Reperfusion in Acute Myocardial Infarction). Patients (n = 1059) with anterior or high-risk inferior STEMI presenting to non-PCI centers within 12 h of symptom onset treated with tenecteplase and other standard antithrombotic therapies were randomized to either a pharmacoinvasive strategy (urgent transfer, angiography and PCI when appropriate within 6 h) or standard treatment (including rescue PCI, or angiography and PCI when appropriate beyond 24 h). The composite primary endpoint of 30-day death, reinfarction, recurrent ischemia, new or worsening heart failure, and cardiogenic shock occurred less frequently in the routine early PCI patients compared to the standard treatment patients (11.0% vs. 17.2%, P = 0.004). Based upon these findings, consistent with other studies, we believe that STEMI patients who cannot undergo timely primary PCI should receive prompt fibrinolysis followed by initiation of an immediate transfer to a PCI-capable hospital without waiting to see whether reperfusion is successful.
在能够快速实施的情况下,直接经皮冠状动脉介入治疗(PCI)已被证明在降低ST段抬高型心肌梗死(STEMI)死亡率方面优于溶栓治疗。然而,许多STEMI患者就诊的医院没有PCI治疗能力,往往无法在指南推荐的时间内接受PCI治疗;相反,他们接受溶栓作为初始再灌注治疗。多项研究探讨了在溶栓后不久进行PCI,结合两种治疗方法优点的可能性,包括TRANSFER-AMI(急性心肌梗死溶栓后常规血管成形术和支架置入以增强再灌注试验)。症状发作12小时内就诊于非PCI中心的前壁或高危下壁STEMI患者(n = 1059),接受替奈普酶和其他标准抗栓治疗,被随机分为药物侵入性策略组(紧急转运,6小时内适时进行血管造影和PCI)或标准治疗组(包括补救性PCI,或24小时后适时进行血管造影和PCI)。与标准治疗组患者相比,常规早期PCI组患者30天死亡、再梗死、复发性缺血、新发或加重的心力衰竭以及心源性休克的复合主要终点发生率更低(11.0%对17.2%,P = 0.004)。基于这些发现,与其他研究一致,我们认为无法及时进行直接PCI的STEMI患者应接受及时溶栓治疗,随后立即转至有PCI治疗能力的医院,而不必等待观察再灌注是否成功。
