US EditionCoffee Might Reduce Heart Rhythm Risk
A randomized trial found daily coffee drinkers had a 39% lower risk of atrial fibrillation recurrence compared to abstainers, challenging prior caffeine avoidance advice.
- Researchers ran a randomized clinical trial of 200 adults across five hospitals in the United States, Canada, and Australia, assigning half to avoid coffee and half to drink at least one cup daily and tracked AF episodes over six months.
- Experts have long advised limiting caffeine for AF patients because it can raise heart rate, but researchers tested coffee's impact after observational clues and its common consumption.
- Showing a 39 percent relative reduction, the trial found lower AF recurrence among daily coffee drinkers but noted unblinded design and self-reported intake limit generalizability to trial participants with prior coffee history.
- Clinical guidance now aligns with these findings, reassuring patients with atrial fibrillation who enjoy caffeinated coffee, though healthcare providers advise discussing individual triggers.
- Atrial fibrillation affects more than 10.5 million adults in the U.S. and tens of millions globally; researchers plan to study non–coffee drinkers and mechanisms like exercise and anti-inflammatory compounds.

For years, patients with heart rhythm disorders were strongly advised to stay away from coffee. Caffeine was thought to speed up the heart and worsen symptoms. But new Australian research turns that perception on its head. A daily cup of coffee actually appears to protect against recurrent heart rhythm disorders.
According to an American study, one cup of coffee a day can reduce the risk of atrial fibrillation recurrence by 39%.

A groundbreaking study, the DECAF study, has found that coffee significantly reduces the risk of atrial fibrillation (AFib), a common and dangerous heart rhythm disorder. The study involved 200 patients with a history of AFib or atrial flutter, who were randomly assigned to either drink coffee daily or avoid it entirely for six months. The coffee-drinking group experienced a 39 percent lower risk of recurring AFib episodes compared to the group …
