Digital Interventions for Alcohol and Atrial Fibrillation Severity

This study is looking at how digital messages can help people with atrial fibrillation (AF), a common heart rhythm problem, manage their alcohol intake. You could join if you are 21 or older, have AF, use a smartphone, and drink alcohol at least once a month. The study compares two approaches: one group gets messages encouraging them to follow current guidelines for moderate drinking, while the other group gets messages encouraging them to avoid all alcohol. Researchers will track changes in your AF severity over one year to see which approach is more effective. The study is currently unclear on its recruitment status.

Study design
This is a single-center, randomized, controlled study with a planned enrollment of 1000 participants. Participants will be randomly assigned to one of two digital health interventions.
What's involved
You will receive weekly app and text-based messages for one year. Your alcohol consumption and AF episodes will be assessed through regular surveys.
Compensation
Not stated in the trial record.
Follow-up
Your atrial fibrillation severity will be measured from the start of the study to one year of participation.

  • Change in atrial fibrillation severity at one yearFrom baseline to one year of study participation.

    The primary outcome will be change in atrial fibrillation severity at one year, defined by a change in the Atrial Fibrillation Effect on Quality-of-Life Questionnaire (AFEQT) score from baseline to one year associated with alcohol abstinence. Based on previously reported values of clinically relevant change in AFEQT score (PMID 31092022), the investigators estimate the change in mean AFEQT score from baseline to 1 year to be 5.4±17.03 in the Alcohol Abstinence group and 0.2±15.17 in the Contemporary Guideline-Adherence group, giving a 5.2 difference between the two groups. The investigators estimate that 1,000 patients would provide \~99% power to detect this difference with as much as 30% overall attrition, and 30% crossover from abstinence to drinking regularly and 20% crossover from drinking regularly to abstinence.
