Prevalence of Subclinical Atrial Fibrillation in Heart Failure With Preserved Ejection Fraction
- Cross-sectional study
Authors' conclusion
Patients with HFpEF had a higher prevalence of subclinical AF than participants without HF from a community-based study.
Study context
- Population
- Patients with heart failure with preserved ejection fraction (HFpEF) without prior atrial fibrillation (AF) vs community controls without HF (MESA), same ECG monitoring
- Participants
- 90 vs 1,230
- Exposure
- HFpEF vs non-HF MESA participants
- HFpEFn = 90
- MESAn = 1,230reference
- Outcome
- Prevalence of subclinical AF
