The Triglyceride‐Glucose Index Predicts Early Recurrence of Atrial Fibrillation After Ablation in Non‐Diabetic Patients

A total of 417 non-diabetic patients with AF after RFCA were included in this study. Multivariate analysis identified the TyG index, left atrial diameter (LAD), and age as independent risk factors for ER of AF after RFCA in non-diabetic patients. ROC analysis demonstrated that the TyG index predicted ER with an area under the curve (AUC) of 0.687. Incorporating the TyG index into a clinical model (containing age and LAD) significantly improved its predictive value, with a net reclassification improvement (NRI) of 0.629 and an integrated discrimination improvement (IDI) of 0.068 CONCLUSIONS: The TyG index is an independent predictor of early AF recurrence after catheter ablation in non-diabetic patients.
