Patient-reported Outcomes In Relation To Continuously Monitored Rhythm Before And During Two Years After Atrial Fibrillation Ablation Using A Disease-specific And A Generic Instrument

• Background: Patients with AF have a lower health-related quality of life (HRQoL) than the general population.Objective: To assess the effect of AF ablation on AF-specific and generic patient-reported outcomes (PRO), compare it to a Swedish age- and sex-matched population and evaluate any association with the AF burden.Methods: Patients scheduled for AF ablation completed the generic SF-36 and the AF-specific PRO questionnaires before and six, 12 and 24 months after AF ablation. All patients underwent continuous ECG monitoring via an implantable loop recorder.Results: 54 patients completed the follow-up. After ablation, the generic SF-36 improved and both summary scores reached normative levels at 24 months, while physical functioning, role-physical and vitality remained lower than norms. Responders with an AF burden ≤0.5% at each visit after ablation reached the norms in all domains, while non-responders reached norms in only social functioning and MCS. All AF6 items and the sum score showed moderate to large improvement in both responders and non-responders. Higher AF burden was independently associated with poorer PCS and AF6 sum score. The AF sum score correlated with all SF-36 domains, but all AF6 items did not correlate with the SF-36 summary scores.Conclusion: The AF-specific AF6 questionnaire was more sensitive to changes in PRO related to AF burden than was the generic SF-36. Higher AF burden after ablation was associated with poorer AF-specific PRO and poorer generic physical but not mental health. Focusing on AF-specific symptoms and their impact on quality of life as an outcome after AF ablation is reasonable, as improving PROs is the main goal of AF ablation.
