Healthcare utilisation and quality of life according to atrial fibrillation burden, episode frequency and duration.

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.
