    A retrospective dual-cohort study assessed admission risk heterogeneity in patients with diabetic acute myocardial infarction (DM-AMI).

  • 2

    The study developed a model for predicting 180-day mortality using eight admission variables, including age and glucose levels.

  • 3

    The model demonstrated good discrimination in the development cohort with a C-index of 0.848 and maintained performance in external validation.

  • 4

    Comparison with the GRACE score showed similar discrimination, but the combined model improved performance with a significant ΔAUC.

  • 5

    The model requires recalibration for accurate risk assessment in external settings due to observed risk overestimation in validation.
