NCT05121519 · Status: COMPLETED · Phase: NA · Type: INTERVENTIONAL · Enrollment: 200

No results posted yet for this study

Summary

Given both the increasing population impact of atrial fibrillation (AF) and the widespread consumption of coffee in society, determining an associated benefit or risk of coffee consumption on AF is of great clinical relevance. This study will evaluate the effect of randomly assigning participants undergoing cardioversion to coffee abstinence or coffee continuation over a 6 month period. This study will provide the first, randomized evaluation of coffee on AF outcomes and will provide important information on whether or not coffee has any effect on AF recurrence.
