  • Stopped: an ongoing trial was terminated, suspended or withdrawn.
  • Notable: the trial’s plan changed such as a big move in its timeline or size, a new primary endpoint, sponsor or phase, or recruiting opened or resumed.
  • Minor: routine progress and housekeeping, such as sites added or enrollment closed.
The investigators analyze the impact of exercise and ablation in patients with symptomatic short-persistent atrial fibrillation (Afib) and heart failure with preserved ejection fraction (HFpEF). It is hypothesized that the combination of ablation and exercise better improves peak oxygen consumption (VO2peak) through improvement of peripheral (exercise training) and central (ablation) adaptations. Exercise intervention will contain a 12-week combined, video-based, supervised, endurance, resistance and respiratory training.
