    This study evaluated the association between insulin resistance indices and long-term major adverse cardiovascular events in atrial fibrillation patients post-ablation.

  • 2

    A total of 922 non-valvular atrial fibrillation patients who underwent radiofrequency catheter ablation were included in this retrospective observational study.

  • 3

    METS-IR and TyG-BMI were significantly associated with increased risk of major adverse cardiovascular events after full multivariable adjustment.

  • 4

    METS-IR provided the greatest incremental predictive value over established clinical risk factors, improving the C-statistic from 0.702 to 0.717.

  • 5

    The study highlights the need for improved risk stratification in atrial fibrillation patients following catheter ablation to predict adverse outcomes.
