Catheter-Based Ablation to Improve Outcomes in Patients with Atrial Fibrillation and Heart Failure with Preserved Ejection Fraction: Rationale and Design of the CABA-HFPEF-DZHK27 Trial
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
Methodological detailsinvestigator-initiated, prospective, open, multicentre, strategy trial, blinded outcome assessment, Safety outcome: complications of catheter ablation and death, All patients receive anticoagulation, rate control and heart failure (HF) management per current guidelines
