Symptoms Burden as a Clinical Outcomes Assessment in Heart Failure Patients With Atrial Fibrillation

JACC Heart FailPublished

  • Methodological validation study (secondary analysis of the GENETIC-AF randomised trial)

Authors' conclusion

Measurement of symptoms burden throughout clinical trial follow-up is feasible in AF/HF

Study context

Population
Patients with heart failure (HF) and atrial fibrillation (AF) in a trial comparing 2 AF prevention treatments
Participants
267 patients
Comparison
SxBAF vs time to first symptomatic AF event as a trial endpoint

Performance

As reported in the abstract

Validation of SxBAF (AFSQ linked to ECG-documented AF)

Correlation of SxBAF with device-detected AF burden (Spearman's ρ)

0.74; P < 0.0001

Further findings

SxBAF discrimination

Identified treatment group differences in CV serious adverse events and AF interventions, and in recent-onset AF provided specificity for AF- or worsening HF-associated symptoms
P < 0.001 for each
