This study aimed to test the predictive performance of the updated ACTION, GRACE, and CADILLAC risk scores (RS’s) for long-term mortality in patients with acute myocardial infarction (AMI) undergoing percutaneous coronary intervention (PCI). The study included individuals from 2 independent cohorts: derivation cohort (N = 1901) and validation cohort (N = 728). From the derivation cohort, we used Cox regression analysis to determine that the updated ACTION, GRACE, and CADILLAC RS’s were associated with long-term mortality. The concordance (C) statistics of the 3 RS’s were 0.682, 0.703 and 0.734, respectively. We used the validation cohort to validate the results. Moreover, the discriminatory performance of the updated ACTION RS for predicting long-term mortality in both the respective derivation and validation cohorts was similar to the discriminatory performance of the GRACE and CADILLAC RS’s (ACTION vs. GRACE: z = 0.684, p = 0.494; ACTION vs. CADILLAC: z = 1.638, p = 0.101) and (ACTION vs. GRACE: z = 0.460, p = 0.646; ACTION vs. CADILLAC: z = 0.290, p = 0.772). Despite their development over a decade ago, GRACE and CADILLAC RS’s maintain good performance for predicting the long-term mortality of AMI patients undergoing PCI. As a new risk model, the updated ACTION RS also predicts long-term mortality, and its discriminatory performance is similar to that of the GRACE and CADILLAC RS’s.
