Extracorporeal cardiopulmonary resuscitation (E-CPR) using veno-arterial extracorporeal membrane oxygenation (VA-ECMO) is a novel lifesaving method for refractory cardiac arrest. Although VA-ECMO preserves end-organ perfusion, it may affect left ventricular (LV) recovery due to increased LV load. An emerging treatment modality, ECPELLA, which combines VA-ECMO and a transcatheter heart pump, Impella, can simultaneously provide circulatory support and LV unloading. In this single-site cohort study, we assessed impact of ECPELLA support on clinical outcomes of refractory cardiac arrest patients.
We retrospectively reviewed 165 consecutive cardiac arrest patients, who underwent E-CPR by VA-ECMO with or without intra-aortic balloon pump (IABP) or ECPELLA from January 2012 to September 2021. We assessed 30-day survival rate, neurological outcome, hemodynamic data, and safety profiles including hemolysis, acute kidney injury, blood transfusion and embolic cerebral infarction.
Among 165 E-CPR patients, 35 patients were supported by ECPELLA, and 130 patients were supported by conventional VA-ECMO with or without IABP. Following propensity score matching of 30 ECPELLA and 30 VA-ECMO patients, the 30-day survival (ECPELLA: 53%, VA-ECMO: 20%, p < 0.01) and favorable neurological outcome determined by the Cerebral Performance Category score 1 or 2 (ECPELLA: 33%, VA-ECMO: 7%, p < 0.01) were significantly higher with ECPELLA. Patients receiving ECPELLA also showed significantly higher total mechanical circulatory support flow and lower arterial pulse pressure for the first 3 days (p < 0.01) of treatment. There were no statistical differences in safety profiles between treatment groups.
ECPELLA may be associated with improved 30-day survival and neurological outcome in patients with refractory cardiac arrest.
使用静脉-动脉体外膜肺氧合(VA-ECMO)的体外心肺复苏(E-CPR)是一种用于难治性心脏骤停的新型救生方法。尽管VA-ECMO可维持终末器官灌注,但由于左心室(LV)负荷增加,它可能会影响左心室恢复。一种新兴的治疗方式,即结合VA-ECMO和经导管心脏泵Impella的ECPELLA,可同时提供循环支持和左心室减负。在这项单中心队列研究中,我们评估了ECPELLA支持对难治性心脏骤停患者临床结局的影响。
我们回顾性分析了2012年1月至2021年9月期间连续接受VA-ECMO进行E-CPR的165例心脏骤停患者,这些患者接受或未接受主动脉内球囊泵(IABP)或ECPELLA治疗。我们评估了30天生存率、神经功能结局、血流动力学数据以及包括溶血、急性肾损伤、输血和栓塞性脑梗死在内的安全性指标。
在165例接受E-CPR的患者中,35例接受了ECPELLA支持,130例接受了常规VA-ECMO(伴或不伴IABP)支持。在对30例ECPELLA患者和30例VA-ECMO患者进行倾向评分匹配后,ECPELLA组的30天生存率(ECPELLA:53%,VA-ECMO:20%,p<0.01)和由脑功能分类评分1或2确定的良好神经功能结局(ECPELLA:33%,VA-ECMO:7%,p<0.01)显著更高。接受ECPELLA治疗的患者在治疗的前3天还表现出总机械循环支持流量显著更高且动脉脉压更低(p<0.01)。治疗组之间在安全性指标方面无统计学差异。
ECPELLA可能与难治性心脏骤停患者30天生存率和神经功能结局的改善相关。
