Heart failure & cardiomyopathiesDiagnostic or prognostic study
Utility and Validity of the HFA-PEFF and H2FPEF Scores in Patients With Symptomatic Atrial Fibrillation
- Diagnostic accuracy study
- consecutive patients
- invasive gold standard
Authors' conclusion
Against a gold standard of invasively diagnosed HFpEF, the HFA-PEFF and H2FPEF scores demonstrate only moderate accuracy in patients with AF and should be utilized with caution in this cohort of patients.
Study context
- Population
- Patients with symptomatic atrial fibrillation (AF) and preserved EF scheduled for AF ablation88 with invasive heart failure with preserved ejection fraction (HFpEF)
- Participants
- 120 patients
- Comparison
- HFA-PEFF vs H2FPEF score for HFpEF diagnosis
- Outcome
- Sensitivity and specificity for HFpEF vs invasive diagnosis (mean left atrial pressure at rest and after 500 mL fluid infusion)
Performance
As reported in the abstract
Diagnosis of HFpEF
| Test or model | Sensitivity | Specificity | AUC |
|---|---|---|---|
| HFA-PEFF | 40% | 91% | 0.663 |
| H2FPEF | 69% | 66% | 0.707 |
- HFA-PEFF vs H2FPEF: P = 0.636 — similar overall accuracy
