Digital interventions to manage alcohol consumption and atrial fibrillation severity

Official title: Digitally Rendered Interventions And Knowledge To Limit Ethanol-Associated Atrial Fibrillation Severity

Run by University of California, San Francisco · NCT06995391 · Data updated 2026-11-12

This study is testing whether using a special app and text messages to help people cut down or quit drinking alcohol can improve heart rhythm problems in those with atrial fibrillation.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are English-speaking adults over 21 with paroxysmal or persistent atrial fibrillation who consume alcohol at least once a month.

Probably not a fit

Patients who are currently pregnant, have permanent AF, or are instructed by a healthcare professional to avoid alcohol will not benefit from this study.

What this trial studies

This clinical trial investigates the effects of two digital health interventions on atrial fibrillation (AF) severity among individuals who consume alcohol. Participants will be randomly assigned to either a guideline-adherent moderate alcohol consumption group or an alcohol abstinence group, receiving weekly messaging through an app and text. The study aims to assess the impact of these interventions on AF episodes and severity over one year, utilizing both self-reported data and objective testing for alcohol consumption. The trial will include at least 1,000 participants aged 21 and older with a history of paroxysmal or persistent AF.

Why it matters

Potential benefit: If successful, this study could provide insights into effective strategies for managing atrial fibrillation severity related to alcohol consumption.

How similar studies have gone: While studies have explored alcohol's impact on AF, this specific approach comparing moderate consumption with abstinence is relatively novel.
