Abstract

Background: Cryoballoon ablation (CBA) is recommended for patients with paroxysmal atrial fibrillation (AF) refractory to anti-arrhythmic drugs. However, only 70% of patients benefit from an initial CBA. There is a growing evidence that pretreatment with angiotensin converting enzyme inhibitors (ACE-I) and angiotensin receptor blocker (ARB) decreases recurrence of AF post ablation, particularly in non-paroxysmal AF undergoing radiofrequency ablation. The role of ACE-I and ARB in patients with paroxysmal AF in CBA remains unknown. We decided to investigate the role of ACE-I and ARB in preventing recurrence of atrial arrhythmias (AA) following CBA for paroxysmal AF. Methods: We followed 103 patients (Age 60.6 ± 9.1, 29% women) with paroxysmal AF undergoing CBA for one year post procedure. Recurrence was assessed by documented AA on EKG or any form of long-term cardiac rhythm monitoring. A multivariable cox proportional hazard model was used to assess if ACE-I or ARB treatment predicted risk of AA recurrence. Results: After a one year follow up, 19 (18.4%) participants developed recurrence of AA. Use of ACE-I or ARB therapy was noted in the study population. Patients on ACE-I/ARB had a greater prevalence of hypertension and coronary artery disease. On a multivariate model adjusted for baseline demographics and risk factors for AF, ACEI or ARB therapy did not prevent recurrence of AA following CBA (Table, p=0.72). Similarly, on Kaplan-Meier analysis pretreatment with ACE-I/ARB did not predict time to first recurrence of AA (Figure, p=0.2173). Conclusion: In our study population pre-ablation treatment with an ACE-I or an ARB had no influence on the recurrence of AA following CBA for paroxysmal AF.
