Association between postprocedural echocardiographic and laboratory data and clinical outcomes in patients with preserved ejection fraction after catheter ablation for atrial fibrillation
Authors' conclusion
The AF-HFA-PEFF score is simpler than the HFA-PEFF score and is equally associated with 3-year cardiovascular events and AF recurrence.
Study context
- Population
- Patients with preserved EF who underwent atrial fibrillation (AF) ablation
- Participants
- 354 patients
- Exposure
- AF-HFA-PEFF score vs original HFA-PEFF score
- Outcome
- CV events and AF recurrence
- Follow-up
- 3 years
Methodological detailsrisk score derivation and validation (random 50% split)

Main finding
As reported in the abstract
3-year CV events (validation)
3-year CV events (validation)
AF recurrence
P < 0.001
- AF-HFA-PEFF score ≥4 vs AF-HFA-PEFF score <4: P < 0.001 — CV events
Observational data: associations, not effects.
