Authors' conclusion

This limited small-scale randomised study showed that CA in older patients with PerAF and HFrEF was associated with a lower likelihood of unplanned hospitalisations due to worsening heart failure with improvement in LVEF and lower AF burden.

Study context

Population
Older patients with persistent atrial fibrillation (PerAF) and heart failure with reduced ejection fraction (HFrEF)mean age 69.5±3.9 years, randomly allocated
Participants

  • CA groupn = 45
  • Medical rate control (MRC) groupn = 44
Primary endpoint
