Ablation for atrial fibrillation improves the outcomes in patients with heart failure with preserved ejection fraction
Main findingResult — go to the resultAdjusted hazard ratio 0.55 95% CI 0.37–0.82Authors' conclusion
Among patients with HFpEF and AF, the strategy of AF ablation to maintain SR was associated with a lower risk of the composite outcome of all-cause death or rehospitalization for worsening heart failure.
