Dynamic Modified Early Warning Score for predicting postoperative mortality in acute type A aortic dissection: a retrospective study.

ABSTRACT:

Background

The Modified Early Warning Score (MEWS) is a valuable tool for predicting in-hospital mortality, yet it is seldom applied to acute type A aortic dissection (AAAD). This study aimed to evaluate the predictive accuracy of MEWS at different times within the first 24 hours after AAAD surgery, and to investigate the association between MEWS trajectories and postoperative mortality.

Methods

This retrospective study included 279 patients who underwent AAAD surgery from January 2020 to December 2022. MEWS was calculated at 0, 4, 8, 12, 16, 20, and 24 hours postoperatively. Predictive value for mortality was assessed using receiver operating characteristic (ROC) curves. Latent class growth modeling (LCGM) was applied to classify MEWS trajectories and analyze their associat
