Prediction of 5-Year Mortality in Patients with Chronic Coronary Syndrome Treated with Elective Percutaneous Coronary Intervention: Role of the ACEF Score

We evaluated the predictive power of age, creatinine, and ejection fraction (ACEF) score on mortality at 5-year follow-up in a population of 471 patients with chronic coronary syndrome (CCS) treated with percutaneous coronary intervention (PCI). Patients in the ACEF-High tertile showed the highest incidence of death at 5 years (15.7% vs. 2.6% in ACEF-Low and 4.3% in ACEF-Mid; log rank p<0.001). The ACEF score could significantly discriminate between patients who died and those who were still alive at 5 years (AUC 0.741, 95% CI 0.654-0.828), and an ACEF score >1.32 was identified as the optimal cutoff point to predict 5-year mortality (sensitivity 74%, specificity 68%). An ACEF score >1.32 was an independent predictor of 5-year mortality (HR 5.77, 95% CI 2.70-12.31; p<0.001). Our study shows that the ACEF score can predict mortality at 5-year follow-up in patients with CCS treated with PCI.
