This is an open label, multi-center, randomized parallel control clinical trial. HFrEF patients with persistent atrial fibrillation are 1:1 randomized into the AF ablation group or the medical therapy (rate or rhythm control) group. Markers of HFrEF severity, including composite of death from any cause or worsening of heart failure that led to an unplanned overnight hospitalization,exercise hemodynamics, natriuretic peptide levels, and patient symptoms. and other indicators are analyzed to demonstrate the role of AF ablation in comparing the effects of AF ablation vs usual medical therapy for HFrEF patients with persistent atrial fibrillation.
This is an open label, multi-center, randomized parallel control clinical trial, to examining thethe clinical outcomes of AF ablation on HFrEF patients with persistent atrial fibrillation.
