Hyperuricemia as a risk factor for atrial fibrillation recurrence after radiofrequency ablation

Key Result

Baseline uric acid levels were significantly higher in patients who experienced atrial fibrillation recurrence after radiofrequency ablation compared to those without recurrence (480.3 vs 330.7 μmol/L

Key Points

• This research aims to determine the role of hyperuricemia as a risk factor for atrial fibrillation recurrence after radiofrequency ablation.
• Conducted a randomized trial involving patients undergoing radiofrequency ablation for atrial fibrillation.
• Evaluated hyperuricemia levels before and after the procedure.
• Assessed recurrence rates of atrial fibrillation in relation to hyperuricemia status.
• Patients with hyperuricemia had a higher recurrence rate of atrial fibrillation, with a 30% event rate compared to 15% in normouricemic patients.
• The hazard ratio for recurrence in hyperuricemic patients was 2.1 (95% CI 1.5-3.0, p=0.002).
• Adjustments for confounders maintain the significance of hyperuricemia as a risk factor.
