Aims Catheter-based atrial fibrillation (AF) ablation has become an important therapeutic option in AF patients. Although there has been significant improvent in procedural success, post-procedural AF recurrences are continuing to be a major clinical problem. To the best of our knowledge, the impact of pre-procedural serum uric acid (SUA) level, as a pro-oxidant and pro-inflammatory marker, on AF recurrence following cryoballoon-based AF ablation has never been studied before. The objective of this study was to establish whether there is a relationship between levels of SUA and recurrence of paroxysmal AF after catheter ablation.
