INS and Insulin resistance: Others compared the ability of four non-insulin-dependent IR indices to predict AF recurrence after RFA [the Metabolic Score for Insulin Resistance (METS-IR), TyG, TyG-BMI, and Triglyceride-to-HDL-Cholesterol Ratio (TG/HDL-C Ratio)] and found that the TyG, METS-IR, and TyG-BMI indices were independently associated with the risk of AF recurrence after surgery (HRs were 1.18, 1.82, and 1.71 after adjusting for confounders; all p-values were <0.05), with the TyG-BMI index having the highest predictive power (AUC = 0.608) [52].
