Purpose
Stanford type A aortic dissection (TAAD) is the most common and fatal type of dissection. An easier-to-use risk stratification may help eliminate bias in patients at high risk of dissection. The age, serum creatinine, and ejection fraction (ACEF) score is a simple risk model developed to predict the mortality risk of elective coronary artery bypass graft surgery. This study aimed to evaluate the relationship between preoperative ACEF score and operative mortality in patients with TAAD undergoing emergency surgery.
Methods
In this retrospective cohort study, 113 patients diagnosed with TAAD between January 2017 and September 2021 were evaluated. The primary endpoint was operative mortality. Receiver operating characteristic analysis was performed for the ACEF score, ACEF II score, and European System for Cardiac Operative Risk Evaluation II. Univariate and multivariate analyses of operative mortality were performed using the logistic regression model.
Results
Operative mortality occurred in 23 (20.4%) patients. The cutoff ACEF score was calculated as 1.1 for predicting operative mortality (area under the curve = 0.712, P value = 0.002, sensitivity = 74.0%, specificity = 67.8%, likelihood ratio = 2.3). Based on the cutoff value, 46 (40.7%) patients had a high ACEF score (ACEF ≥ 1.1) and 67 (59.3%) patients had a low ACEF score (ACEF < 1.1). The high ACEF score was associated with an increased incidence of operative mortality compared with the low ACEF score (37.0% vs. 9.0%; P = 0.001).
Conclusions
The ACEF score can be used as a useful and relatively simple tool for risk stratification before TAAD surgery. However, the ACEF score is only indicated for risk assessment and should not affect treatment.
