The purposes of this study are to identify a patient cohort that would benefit from the use of mechanical circulatory support (MCS) in the presence of the Eurotransplant high-urgency (HU) program.
Sixty-five patients (heart transplantation (HTx) group, 77%) underwent heart transplantation and 17 patients (D group, 20%) died while on the HU waiting list. These 82 patients were included in this retrospective study.
The mean waiting time on HU list was 18.3+/-17.7 days in HTx group and 12.5+/-9.4 days in D group (p=0.075). The average weekly allocation rate from the active HU list was 27.7%, and the mean weekly waiting-list mortality was 12.1%. The use of intra-aortic balloon pumping (p=0.005), mechanical ventilation (p=0.007), higher dose of dobutamine (0.005), lower serum level of sodium (p=0.046), and higher serum level of C reactive protein (CRP) (0.040) at the registration of HU listing were associated with waiting-time mortality, and the serum creatinine level more than 1.5mg/dl (p=0.007, odds ratio; 14.5, 95% CI; 2.1-102.0) and the serum CRP level more than 10mg/l (p=0.026, odds ratio; 6.3, 95%CI; 1.2-31.4) were identified as significant predictors.
It would be appropriate that a patient who would not be able to tolerate one or two weeks waiting time to be considered as a candidate for MCS implantation in the presence of the HU program. The patient selection criteria for MCS implantation should include not only hemodynamic parameters, but also the aspect of a beginning multi-organ failure.
本研究的目的是确定在欧洲移植高紧急度(HU)计划下能从使用机械循环支持(MCS)中获益的患者队列。
65例患者(心脏移植(HTx)组,77%)接受了心脏移植,17例患者(D组,20%)在HU等待名单上死亡。这82例患者被纳入这项回顾性研究。
HTx组在HU名单上的平均等待时间为18.3±17.7天,D组为12.5±9.4天(p = 0.075)。活跃HU名单的平均每周分配率为27.7%,平均每周等待名单死亡率为12.1%。在HU名单登记时使用主动脉内球囊反搏(p = 0.005)、机械通气(p = 0.007)、更高剂量的多巴酚丁胺(0.005)、更低的血清钠水平(p = 0.046)以及更高的血清C反应蛋白(CRP)水平(0.040)与等待时间死亡率相关,血清肌酐水平超过1.5mg/dl(p = 0.007,比值比;14.5,95%置信区间;2.1 - 102.0)和血清CRP水平超过10mg/l(p = 0.026,比值比;6.3,95%置信区间;1.2 - 31.4)被确定为显著预测因素。
在HU计划下,无法耐受一至两周等待时间的患者适合被视为MCS植入的候选者。MCS植入的患者选择标准不仅应包括血流动力学参数,还应包括多器官功能开始衰竭的方面。
