Abstract
BACKGROUND
Impaired quality of life due to atrial fibrillation (AF), which often includes decreased activity level, is an indication for ablation. However, the impact of ablation for AF on activity is poorly understood.
OBJECTIVE
To assess the impact of ablation on activity minutes per day using continuous accelerometer data from cardiac implantable electronic devices (CIED).
METHODS
Using the Optum® Health Record dataset (2007-2019) linked with the Medtronic CareLink® database, we identified patients who had a CIED with AF detection and accelerometer capabilities. Patients with a device that transmitted heart rhythm and activity data ≥ 3 months prior to- and ≥ 12 months following ablation were included in analysis. The associations between ablation and activity minutes were assessed in each CIED type.
RESULTS
Of 4297 eligible patients who underwent AF ablation, 409 (9.5%) (65% Male, 67.3±9.8 years, 64% paroxysmal AF) were included in analysis. The average AF burden and activity minutes per day pre-ablation were 30.9±37.4% and 175±99 minutes, respectively. Following ablation, relative AF burden decreased by 75.1±53.2% (p<0.001). There was no change in activity minutes per day following ablation in the entire cohort (average change: -0.10±36.2 min, p=0.96). There were also no clinically significant changes in activity minutes post-ablation in subgroups based on CIED, season of ablation, quartile of AF burden change, and quartile of age at the time of ablation.
CONCLUSION
There were no clinically significant changes in activity minutes per day in patients with CIEDs following ablation for AF.
