联合使用血尿素氮和sPESI评估急性重症肺栓塞病人的30天死亡风险
Zhongshan Daxue xuebao. Yixue kexue ban, 2022 目的探究血尿素氮（BUN）是否有助于增强简化版肺栓塞严重指数（sPESI）的危险分层能力。方法本回顾性研究纳入了在MIMIC Ⅲ数据库中被诊断为急性重症肺栓塞的患者，并将他们在30 d内的死亡率作为此次研究的主要结局。根据ROC曲线的最大Youden指数计算BUN和sPESI的最佳截断值；使用Kaplan-Meier曲线评价BUN、sPESI及其组合在总队列和亚组中的危险分层能力。结果本研究共纳入了250名急性重症肺栓塞患者。BUN和sPESI均为30 d死亡率的独立预测指标。BUN的最佳截断值为21 ...
