ABSTRACT
Background:
Hyperuricemia (HU) has been reported to be associated with a high incidence of atrial fibrillation (AF). However, the relationship between HUA and recurrent AF after catheter ablation (CA) is unclear.Methods:
Four hundred consecutive AF patients (paroxysmal/persistent AF [PAF/PsAF] 200/200) who underwent the initial CA were retrospectively enrolled. HU was defined as serum uric acid (SUA) level >7.0 mg/dL. We measured SUA levels 1 day before (pre-CA) and 1 month after CA (post-CA). A second-generation 28 mm cryoballoon was used for pulmonary vein isolation (PVI) for PAF, while PVI plus linear ablation (roof and mitral isthmus lines) by radiofrequency catheter was conducted for PsAF.Results:
During 57 ± 24 months of follow-up, AF recurred in 16% and 42% in PAF and PsAF patients (p < .0001). Pre-CA SUA level in PsAF was significantly higher than that in PAF (6.5 ± 1.3 vs. 5.8 ± 1.3 mg/dL, p < .001). SUA level was significantly decreased after CA in both PAF and PsAF (5.8 ± 1.3 vs. 5.6 ± 1.3 mg/dL; p < .01 and 6.5 ± 1.3 vs. 6.1 ± 1.2 mg/dL; p < .0001, respectively). The association between pre-/post-CA HU and recurrent AF was not identified in PAF, while the incidence of post-CA HU was significantly higher in patients with recurrent AF than those without in PsAF (36% vs. 15%, p < .001). In multivariable analysis, longer AF duration and the presence of post-CA HU were identified as independent predictors of AF recurrence in PsAF (OR1.01, 95%CI1.003-1.011, p = .0001 and OR2.77, 95%CI1.333-5.755, p = .007, respectively).Conclusions:
SUA level was significantly higher in PsAF than PAF patients. The presence of post-CA HU was strongly related to AF recurrence in PsAF patients.
