Why the study?
Does radio-frequency catheter ablation improve sleep quality, and does baseline sleep quality predict AF recurrence in patients with paroxysmal atrial fibrillation?

Key result
Patients with unstable sleep before radio-frequency catheter ablation had a significantly lower risk of atrial fibrillation recurrence compared to the reference group (HR 0.32; 95% CI 0.12-0.83).

Unstable pre-ablation sleep associated with lower AF recurrence; hypothesis-generating in this cohort and requires prospective validation before clinical use.

Does radio-frequency catheter ablation improve sleep quality, and does baseline sleep quality predict AF recurrence in patients with paroxysmal atrial fibrillation?
Radio-frequency catheter ablation improves sleep quality in patients with paroxysmal atrial fibrillation, and worse baseline sleep quality paradoxically predicts a lower risk of AF recurrence.
Hazard Ratio: 0.32 (95% CI 0.12–0.83)
Kim et al. (2020) conducted a cohort in Paroxysmal atrial fibrillation (n=225). Unstable sleep before radio-frequency catheter ablation vs. Second tertile of sleep quality was evaluated on Atrial fibrillation recurrence (HR 0.32, 95% CI 0.12-0.83). Patients with unstable sleep before radio-frequency catheter ablation had a significantly lower risk of atrial fibrillation recurrence compared to the reference group (HR 0.32; 95% CI 0.12-0.83).
