Abstract
Background: We aimed to evaluate the association between atrial fibrillation (AF) burden, duration and number of episodes with healthcare utilisation and quality of life in patients with early paroxysmal AF without a history of AF.
Methods: In this observational cohort study, we included 417 patients with paroxysmal AF from the Reappraisal of Atrial Fibrillation: interaction between hyperCoagulability, Electrical remodelling and Vascular destabilisation in the progression of AF (RACE V) Study. Patients were monitored with an insertable cardiac monitor for 1 year. Outcomes collected were healthcare utilisation, and quality of life assessed using the Atrial Fibrillation Severity Scale and EuroQol EQ-5D-5L questionnaires.
Results: During 1 year of follow-up, 63 973 AF episodes were detected in 353 (85%) patients. The median AF burden was 0.7% (IQR 0.1-4.0%). AF ablation was performed more frequently in patients with intermediate-to-high AF burdens (>0.2%) (16.2% vs 5.9%, p=0.01) and longer AF episode duration (>1 hour) (15.8% vs 2.0%, p=0.01), whereas cardioversions were more frequent in patients with longer episode duration (>1 hour) (9.5% vs 0%, p=0.04) and intermediate (0.2-1.9%) (but not high) AF burdens (13.6% vs 4.2%, p=0.01). Patients with many episodes (>147) reported higher symptom severity (p=0.001). No differences in symptom severity nor in EQ-5D-5L scores according to AF burden or duration were observed.
Conclusion: In patients with early paroxysmal AF, higher AF burden and longer episode duration were associated with increased rates of healthcare utilisation but not with symptoms and quality of life. Patients with a higher number of episodes experienced more severe symptoms.
