About this trial

The DanAblate-HF trial will investigate whether early catheter ablation treatment for atrial fibrillation in patients with heart failure is superior to standard treatment.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

HF patients with AF within the past 12 months

Clinically assessed Heart Failure with Reduced Ejection Fraction (HFrEF)

An indication for initiation or ongoing guideline directed medical therapy for HFrEF, according to current Heart Failure guidelines

LVEF < 50% at any point during the past 12 months

Disqualifiers

Life-expectancy < 1 year

BMI > 40

Contraindications or unacceptable side effects to rate limiting drugs AND amiodarone

LA size (indexed for BSA) > 60 ml/m2 (volume) on echo within the last year

Trial design

Design model

Parallel

Treatments tested in this trial

  • Catheter ablation

    Procedure/Surgery

    Catheter ablation with pulmonary vein isolation will be the study intervention. Patients randomized to the intervention arm will undergo catheter ablation within six weeks of randomization. In the waiting-time for ablation, patients will receive standard treatment for AF and HF, as per current guideline recommendations. Catheter ablation will be performed at one of six high-volume ablation centers in Denmark. Mode of catheter ablation will be at the discretion of the operator. Radiofrequency ablation, cryo-balloon ablation and pulsed-field ablation will be utilized. The treating physician should ensure successful pulmonary vein isolation after ablation with either post-procedural mapping or pacing, as per current standards. Only pulmonary vein isolation will be performed during the ablation procedure.

Trial outcomes

Primary outcomes

1

Time to hospitalization for worsening HF or cardiovascular death

The primary outcome of the trial is defined as the time from randomization to the composite of one the following, whichever comes first * Hospitalization for worsening HF * Cardiovascular (CV) mortality Hospitalization for worsening HF will be defined as hospital admission primarily for HF (as deemed so by the event adjudication committee) with a duration of at least 24 hours and requiring intensification of diuretic treatment. CV mortality will be defined as all deaths resulting from one or more of the following: HF, stroke, acute myocardial infarction, CV procedural deaths, CV hemorrhage, arrythmia, sudden cardiac death, death due to other CV causes and death of undetermined cause.

Time frame
From baseline to study completion, with a minimum of 1 year
