Does continuing alcohol at current levels after catheter ablation affect AF recurrence, QoL, and thinking ability?
Official title: Impact of Post-ablation Alcohol Intake on Arrhythmia Recurrence, Quality of Life and Cognition in Patients With Atrial Fibrillation
Run by Texas Cardiac Arrhythmia Research Foundation · NCT05510167 · Data updated 2026-11-12
This study tests whether people who regularly drink alcohol can continue at their usual amount after AF ablation without increasing recurrence, hurting quality of life, or affecting thinking.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are adults with paroxysmal or persistent AF who regularly consume more than five drinks per week and are undergoing their first catheter ablation, without severe comorbidities or cognitive impairment.
✕Probably not a fit
Patients with alcohol dependence, non-drinkers, severe heart dysfunction, dementia, or unstable medical conditions may not benefit from this intervention.

What this trial studies
This randomized trial investigates whether continuing current alcohol consumption after catheter ablation for atrial fibrillation influences arrhythmia recurrence, quality of life, and cognitive function. Eligible participants are adults with AF who drink more than five drinks per week and are undergoing a first ablation. The study compares outcomes based on maintaining usual alcohol intake versus modification, with assessments including cognitive testing and QoL measures. The trial is led by the Texas Cardiac Arrhythmia Research Foundation at the Texas Cardiac Arrhythmia Institute and St. David's Medical Center in Austin, TX. Enrollment targets individuals who regularly consume alcohol and meet specific clinical criteria, excluding those with significant comorbidity or cognitive impairment.
Why it matters
Potential benefit: If successful, the trial could clarify safe drinking practices after AF ablation and guide personalized post-procedure recommendations.
How similar studies have gone: There is observational evidence linking alcohol to AF risk and post-ablation outcomes, but randomized data on post-ablation alcohol use are not yet established.
