溶栓联合经皮冠状动脉介入治疗策略的效果和安全性

目的回顾性分析溶栓联合经皮冠状动脉介入治疗(PCI)的效果和安全性。方法北京大学第一医院溶栓联合PCI的心肌梗死患者45例,与同期单纯溶栓(31例)和直接PCI(74例)的心肌梗死病例对比分析。结果冠状动脉造影资料显示溶栓联合PCI组的TIMI3级血流占88.9%,较单纯溶栓组(74.2%)高(P=0.087),与直接PCI组(91.9%)相似(P=0.404)。临床资料显示溶栓联合PCI组的主要心血管事件(MACE)占4.4%,较单纯溶栓组(12.9%)低(P=0.181),与直接PCI组(1.4%)相似(P=0.319)。三组病例的住院死亡率相似(4.4%,6.5%,4.1%)。住院期间的主要出血事件(包括大出血和颅内出血)相似(4.4%,3.2%,1.4%)。结论溶栓联合PCI的再灌注效果可能优于单纯溶栓,至少不逊于直接PCI,且安全性良好。

Evaluation of combined thrombolysis and precutaneous coronary intervention in acute myocardial infarction

Objective Evaluation of the benefit and safety of combined thrombolysis and precutaneous coronary intervention in acute myocardial infarction by retrospective analysis. Methods Precutaneous coronary intervention were performed in 45 patients with acute myocardial infarction immediately after thrombolysis. The clinical and angiographic data were compared with that of 31 patients with thrombolysis alone and 74 patients with primary precutaneous coronary intervention in the same period. Results Angiographic data showed that patients with PCI plus thrombolysis had more frequency of TIMI 3 flow than patients with thrombolysis alone (88.9% vs. 74.2%, P=0.087). Patients with PCI plus thrombolysis and with primary PCI had similar frequency of TIMI 3 flow (88.9% vs. 91.9% P=0.404). Clinical data showed that patients with PCI plus thrombolysis had less major adverse cardiovascular events in hospital than patients with thrombolysis alone (4.4% vs. 12.9%, P=0.181). Patients with PCI plus thrombolysis and with primary PCI had similar major adverse cardiovascular events (4.4% vs. 1.4%, P=0.319). Patients with three strategies of treatment had similar mortality (4.4% vs. 6.5% vs. 4.1%). Patients with three strategies of treatment had similar major bleeding events (4.4% vs. 3.2% vs. 1.4%) in hospital. Conclusion Combined thrombolysis and precutaneous coronary intervention maybe surpass thrombolysis alone, at least similar to primary PCI. This strategy of treatment is safe.
