Association of the HFPEF Risk Score with Recurrence of Atrial Fibrillation Following Pulmonary Vein Isolation.

Background: While atrial fibrillation (AF) and heart failure with preserved ejection fraction (HFpEF) commonly coexist, the efficacy of pulmonary vein isolation in the setting of HFpEF is unclear.

Methods: In a cohort of patients who underwent cryoballoon ablation (CBA) from 2011 to 2016, we calculated the HFPEF risk score, a novel 6-item score (scale: 0-9 points) that accurately predicts the probability of HFpEF. We compared characteristics of patients by HFPEF score and evaluated the association of HFPEF score with 12-month recurrence of AF post-procedure.
