Metabolic dysfunction associated steatotic liver disease is associated with atrial fibrillation recurrence following cryoballoon ablation.

ABSTRACT: Atrial fibrillation (AF) is a common arrhythmia often treated with cryoballoon ablation. The impact of Metabolic-associated fatty liver disease (MASLD), a condition newly defined by a fatty liver index ≥ 60, on AF recurrence post-ablation is unclear. We analyzed 303 patients undergoing cryoballoon ablation for AF. Cox proportional hazards models were used to assess the relationship between MASLD and AF recurrence. Paroxysmal atrial fibrillation was present in 61.1% of patients and 63% were male. Among the patients, 23.4% had MASLD. These patients exhibited larger left atrial diameter and left ventricular end-diastolic dimension. During a median follow-up of 14 months, AF recurrence was more frequent in MASLD patients (45.1% vs. 20.7%). MASLD independently predicted AF recurrence (HR, 2.24
