Abstract
前言:依據行政院衛生福利部十大死因資料統計,心臟病為第二名(行政院衛生福利部,2022),其中心因性猝死(Sudden cardiac death)或心因性休克(Cardiogenic shock)最危急需緊急放置靜脈動脈體外膜氧合(Venoarterial extracorporeal membrane oxygenation, VA-ECMO)維持生命徵象平穩,然而放置靜脈動脈體外膜氧合能恢復週邊灌注,但代價是增加左心室(Left ventricle, LV)後負荷,增加左心室後負荷仍會增加死亡率及合併症,進行左心室減壓術(Left ventricular decompression, LVD)可提高存活率。
方法:本研究為單中心回顧性分析,納入2020 年1 月1 日至 2023 年12 月31 日以衛生福利部雙和醫院就診診斷為心因性休克或心臟驟停接受靜脈動脈體外膜氧合治療為研究對象,分成接受左心室減壓術及未接受左心室減壓術兩組,主要結局為存活至出院率,次要結局包括成功撤除靜脈動脈體外膜氧合且存活超過24 小時及7 天的比例,進行存活曲線分析。
結果:本研究總共納入了 80 名病人資料,研究顯示,左心室減壓組的存活至出院率顯著高於靜脈動脈體外膜氧合單獨治療組(50% vs.23.33%;OR = 3.2857,95% CI:1.137–9.4954,P = 0.0242)。此外,左心室減壓組在24 小時(55% vs. 26.67%;OR = 3.3611,95% CI:1.1756–9.6092,P = 0.0203)及7 天(55% vs. 21.67%;OR = 4.4188,95% CI:1.5098–12.9330,P = 0.0048)成功脫離靜脈動脈體外膜氧合的比例亦顯著高於對照組。左心室減壓組的生存曲線相較體外膜氧合單獨治療組更高,對數排名(log-rank test)分析,結果顯示,對數排名檢定(log-rank test)統計值 3.8277,自由度為1,且P 值為 0.05。兩組間不良事件(如急性腎衰竭 消化出血)發生率無顯著差異(P>0.05)。
結論:左心室減壓術可顯著提高靜脈動脈體外膜氧合治療的住院存活率及脫離靜脈動脈體外膜氧合的成功率,同時未增加嚴重併發症的風險。左心室減壓術可能成為改善因心因性休克患者 心臟驟停患者放置靜脈動脈體外膜氧合治療效果的重要輔助手段,但仍需進一步的大規模隨機對照試驗以驗證其長期效益。
