目的
2
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
2
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
2
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21.5 mg/dL,sPESI的最佳截断值为2.5。在BUN≥21.5mg/dL和sPESI≥3的高风险组别中,患者30 d的死亡率为41.38%,明显高于sPESI≥1的组别(死亡率为14.28%)。在BUN≤21.5mg/dL和sPESI≤2的低风险组别中,死亡率为4.07%,和sPESI=0定义的低危组相近(死亡率为3.85%)。
结论
2
联合使用BUN和sPESI可以筛选出病情更为严重的急性重症肺栓塞患者,有助于临床治疗方案的确定。
Objective
2
Whether blood urea nitrogen (BUN) can help increase risk stratification of simplified pulmonary embolism severity index (sPESI) in intensive care unit (ICU) still remains unknown.
Methods
2
A total of 250 patients diagnosed as acute pulmonary embolism (APE) at ICU admission from medical information mart for intensive care Ⅲ database (MIMIC) were included in this retrospective study. The 30-day mortality was defined as the primary outcome. The optimal cut-off values of BUN and sPESI were calculated based on the maximum Youden index of receiver operating characteristic (ROC) curves. The Kaplan-Meier curves were used to evaluate the risk stratification ability of BUN, sPESI, and their combinations in the total cohort and subgroups.
Results
2
BUN and sPESI were both independent predictors for the 30-day mortality. The optimal cut-off value of BUN was 21.5 mg/dL and that of sPESI was 2.5. The 30-day mortality was 41.38% in high-risk group with BUN ≥21.5 mg/dL and sPESI ≥3, which was higher than that in group with sPESI ≥1 (14.28%). And it was 4.07% in low-risk group with BUN ≤21.5 mg/dL and sPESI ≤2, which was near that of the group with sPESI =0 (3.85%).
Conclusions
2
BUN can help define a higher risk group with sPESI in APE admitted to ICU, which can contribute to the clinical management.
