Recruiting at 4 sites No phase Atrial Fibrillation (AF)

Clinical trial for Atrial Fibrillation (AF)

Official title Treating Atrial Fibrillation in Heart Failure With Preserved Ejection Fraction: Ablation or Medication

ClinicalTrials.gov ID: NCT07272902

What this study is testing

What is Rate Control Medications (beta-blockers, calcium channel blockers, digoxin)?

investigational drug regimen being studied as a potential treatment for atrial fibrillation in people with heart failure is designed to slow the heart rate and improve heart rhythm by blocking beta‑adrenergic receptors, inhibiting calcium channels, or increasing vagal tone

Plain-language explanation of the investigational treatment. It is being studied and is not an approved or proven therapy. The study team can confirm the details.

What it's testing
The study aims to see if a larger trial can be done and which treatment, ablation or medicines, better supports survival, reduces hospital stays, and improves quality of life.
Who it's for
Adults who have atrial fibrillation and heart failure with preserved or mildly reduced ejection fraction.
What's involved
Participants will be randomly assigned to either a catheter ablation (a quick procedure that destroys tissue causing irregular beats) or medicines that control heart rate, with follow‑up visits and tests to monitor outcomes.

Who can take part

Ages 18 and older

You may be able to join if

  • Age ≥18 years
  • Diagnosis of atrial fibrillation (documented on Holter, rhythm strip, or ECG)
  • New York Heart Association (NYHA) class II-III heart failure
  • Left ventricular ejection fraction (LVEF) \>40%
  • If HF hospitalization within 6 months prior to screening: NT-proBNP \>200 pg/ml (if not in AF at screening) or \>600 pg/ml (if in AF at screening)

You likely can't join if
