JAHA:急性双心室机械辅助循环用于心源性休克的治疗

2017-10-23 xiangting MedSci原创

这是关于BiPella用于心源性休克的最大规模的回顾性分析。BiPella是可行的,降低心脏充盈压力,并改善一系列原因引起的心源性休克的心输出量。

双心室衰竭与院内高死亡率相关。关于双心室Impella轴流导管(BiPella)用于双心室衰竭疗效的数据非常有限。这项研究的目的是探讨经皮BiPella作为双心室衰竭并发心源性休克患者新型急性机械支持策略的临床应用。

研究人员回顾性分析了美国5家三级医院20例因双心室衰竭而接受BiPella治疗的患者资料。使用Impella 5.0(n = 8),Impella CP(n = 11)或Impella 2.5(n = 1)实现左心室支持。所有患者接受Impella RP右心室(RV)支持。急性心肌梗死(n = 11)、晚期心力衰竭(n = 7)和心肌炎(n = 2)记录了BiPella的使用。左心室和右心室的平均流量为的3.4±1.2和3.5±0.5。院内总死亡率为50%。没有观察到术中死亡。主要并发症包括的肢体缺血(n = 1),溶血(n = 6)和心梗大出血中溶栓(n = 7)。与非存活者相比,幸存者较年轻,BiPella前使用的Inotropes或Vasopressor数量较少,并且在同一手术中更多同时植入两种装置。与非存活者相比,幸存者在BiPella之前具有较低的肺动脉压和RV卒中工作指数。14例受试者定量了RV后负荷指数。在这些患者中,非存活者肺血管阻力较高(6.8; 95%置信区间[95%CI ],5.5-8.1对1.9; 95%CI,0.8-3.0; P <0.01),有效肺动脉弹性下降(1129; 95%CI,876-1383对458; 95%CI,263-653; P <0.01),肺动脉顺应性下降(1.5; 95%CI,0.9-2.1对2.7; 95%CI,1.8-3.6; P <0.05)。

这是关于BiPella用于心源性休克的最大规模的回顾性分析。BiPella是可行的,降低心脏充盈压力,并改善一系列原因引起的心源性休克的心输出量。同时左心室和RV装置植入和较低的RV后负荷可能与BiPella的结局更好相关。未来需要更多的关于BiPella用于心源性休克的前瞻性研究。
