Coffee & AFib Recurrence
Atrial fibrillation, or AFib, is an irregular heartbeat in which the chambers of the heart don't work together as they should, which may cause the heart to beat faster. A recent study found that drinking 1 cup of caffeinated coffee a day reduces a person's risk of recurrent AFib episodes. In this study, 200 adults with persistent AFib, who were also coffee drinkers, were randomly selected either to drink 1 cup of caffeinated coffee a day or to abstain from caffeine for 6 months. At the end of the study, researchers found that the coffee group reduced their risk of AFib recurrence by 39%.
