Summary

This trial will study the effect of coffee on Atrial Fibrillation recurrence.

Who is the study for?
This trial is for men and women over 21 who have atrial fibrillation, drink coffee daily, and are scheduled for electrical cardioversion. They must be willing to either abstain from or continue drinking coffee and attend follow-up calls. Exclusions include allergies to coffee, recent heart surgeries, pregnancy plans within six months, or participation in conflicting studies.
What is being tested?
The study tests the impact of coffee on atrial fibrillation by randomly assigning participants to two groups: one that avoids coffee and another that continues consumption post-electrical cardioversion. The goal is to see if avoiding or consuming coffee affects AF recurrence over a six-month period.
What are the potential side effects?
Since this trial involves lifestyle changes rather than medication, side effects may not be as pronounced but could include withdrawal symptoms like headaches or irritability for those stopping coffee.
