Sleep Quality Change After RFCA In Paroxismal Atrial Fibrillation & Relation of Sleep Stability To the Recurrence: 24 – hour Holter – based Cardiopulmonary Coupling Analysis. Sleep 2018; 41(suppl_1): A327. DOI: 10.1093/sleep/zsy061.879
Objectives:
Sleep instability is highly prevalent in patients with cardiovascular disease (CVD) and evidence supports a casual association of sleep instability with CVD> We investigated the impact of radiofrequency catheter ablation (RFCA) on sleep instability in patients with paroxysmal atrial fibrillation (pAF) and the effect of sleep stability on recurrence of atrial fibrillation.
Conclusions:
Sleep quality was improved after RFCA in patients with pAF. Furthermore, the recurrence rate was significantly lower after RFCA in patient who had pre-RFCA sleep instability (LFC≥50.3%).
Practical Significance:
These results suggest that RFCA can influence sleep quality and sleep quality assessment, and that analyzing routine 24-hr Holter studies can be a predictable marker of recurrence after RFCA in patients with pAF.
