Can coffee lovers with AF keep their daily cup? a trial investigates
NCT ID NCT07738523
First seen Jul 31, 2026 · Last updated Jul 31, 2026
Summary
This trial asks whether people with permanent atrial fibrillation (AF) can continue drinking caffeinated coffee without worsening their heart rate control. Half of the participants will keep their usual coffee habit, while the other half will switch to decaf for a month, then swap. Researchers will measure each person's average heart rate over 24 hours to see if coffee makes a meaningful difference.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- caffeine (via regular coffee consumption)
- What this could lead to
- If moderate coffee intake proves non-inferior to abstinence, people with permanent atrial fibrillation may not need to give up their daily cup.
- What could go wrong
- The trial is small and open-label, relying on self-reported caffeine intake. Individual differences in caffeine metabolism could affect results, and the findings may not apply to all AF patients.
