Utility of age, creatinine, and ejection fraction score in patients with type B aortic dissection undergoing thoracic endovascular aortic repair

Older age, renal and cardiac dysfunction are predictors of poor outcome in aortic dissection. The aim of this study was to evaluate the association of the age, creatinine and ejection fraction (ACEF) score with adverse events in patients with type B aortic dissection (TBAD) undergoing thoracic endovascular aortic repair (TEVAR). The study enrolled 605 patients from January 2010 to July 2015, who were classified into three groups according to the tertiles of ACEF score: Tertile 1 (≤0.77, n = 204), Tertile 2 (0.77–0.96, n = 205) and Tertile 3 (>0.96, n = 196). The association between ACEF, AGEF (age, glomerular filtration rate and ejection fraction) and the updated version of the ACEF (ACEF II) score with adverse events was analyzed. After a median 3.4 years follow-up, 63 (10.4%) patients died. Multivariable analysis revealed that ACEF score was independently associated with long-term mortality (adjusted hazard ratio = 3.54; 95% confidence interval, 2.09–6.01; p
