摘要(Abstract):
目的肺动脉高压(PH)危重患者通常伴随高死亡风险,这强调了识别可靠风险标志物以改善预后的重要性。本研究主要探讨乳酸脱氢酶与白蛋白比值(LAR)与PH患者死亡率之间的关联。方法采用美国重症监护医学信息数据库(MIMIC-IV3.1)数据。根据初始LAR值将受试者分层为三组。采用单变量和多变量Cox回归分析,比较各组在院内、28天和360天死亡风险的差异。Kaplan–Meier生存曲线用于评估组间累计生存率的差异。结果最终纳入了1398名PH患者。经充分调整混杂因素的多变量Cox分析显示,ACAG 评分最高三分位组死亡风险显著升高(院内HR=2.28,95%CI1.69-3.07;28天HR=2.16,95%CI1.65-2.84;360天HR=1.79,95%CI 1.48-2.18;所有p值均<0.01)。结论PH患者LAR水平升高与死亡风险增加相关。早期识别LAR升高患者并实施干预,可能改善该高危患者队列的预后。
