Usefulness of serum uric acid level to predict atrial fibrillation recurrence after cryoballoon-based catheter ablation

Abstract

In this prospective study of patients with paroxysmal AF undergoing cryoablation, increased pre-ablation SUA levels were associated with a higher rate of AF recurrence. Our results support the role of a pre-ablation pro-inflammatory and pro-oxidant environment in the development of AF recurrence after ablation therapy but suggest that other factors are also important.
