All patients receive anticoagulation, rate control and heart failure (HF) management per current guidelines

Authors' conclusion

CABA-HFPEF-DZHK27 will define the role of systematic and early catheter ablation in patients with AF and HFpEF or HFmrEF.

Study context

Population
Patients with paroxysmal or persistent atrial fibrillation (AF) diagnosed within 24 months before enrolment and HFpEF or HFmrEFplanned (approximately)
Participants
1,548 patients
Comparison
Early catheter ablation vs usual care
Primary endpoint
Composite of:
  • CV death
  • Stroke
  • Total unplanned hospitalizations for HF or ACS
Follow-up
Until the end of the trial

Primary result

As reported in the abstract

  • Powered for a rate ratio of 0.75 (two-sided alpha = 0.05, 1-beta = 0.8)
  • design paper; no results reported
