Clinical implication of hyperuricemia on the recurrence of atrial fibrillation after catheter ablation

Abstract

Hyperuricemia has been linked to a heightened incidence of atrial fibrillation (AF). Oseto and colleagues have demonstrated a significant elevation in serum uric acid levels among patients with persistent AF compared to those with paroxysmal AF. 1 Moreover, the presence of post-ablation hyperuricemia has been associated with the recurrence of AF in patients with persistent AF. However, several concerns have been raised. Uric acid is primarily synthesized by xanthine oxidases, pre-
