Fibrilácia predsiení zvyšuje riziko mŕtvice a zlyhania srdca. Prekvapivá ochrana sa pritom možno skrýva v šálke.
For years, medical advice cautioned individuals with atrial fibrillation to limit or avoid coffee consumption. However, new research challenges that long-held belief, suggesting a daily cup of coffee may actually offer protection against the irregular heartbeat. Atrial fibrillation, a common heart condition affecting roughly one in three people during their lifetime, significantly increases the risk of stroke and heart failure.
A recent analysis conducted by researchers at the University of Adelaide and the University of California, San Francisco (UCSF) has revealed a surprising link between coffee intake and a reduced risk of atrial fibrillation recurrence. The findings are prompting a reevaluation of dietary recommendations for those living with the condition.
Information on this topic is available on The Journal of the American Medical Association, The University of Adelaide, New Atlas, Scimex, The Guardian and NBC News.
Key findings from the study include:
- The DECAF study overturned the myth that coffee worsens atrial fibrillation.
- Coffee consumers experienced a 39% lower risk of arrhythmia recurrence.
- Coffee appears to be safe for individuals with atrial fibrillation and may even offer protective benefits.
- Individuals diagnosed with arrhythmia should consult with a cardiologist before making any dietary changes.
The first randomized clinical trial on this topic, known as DECAF (Does Eliminating Coffee Avoid Fibrillation), revealed that coffee is not a foe, but a surprising ally in maintaining heart health. Researchers described the results as “astonishing.”
39% Lower Risk of Arrhythmia Recurrence
The study involved 200 patients with persistent forms of the heart rhythm disorder from Australia, the United States, and Canada. Participants were divided into two groups.
One group of 100 participants was instructed to drink at least one cup of caffeinated coffee daily for six months. The other half was asked to completely abstain from coffee and all caffeinated beverages.
All participants had previously been regular coffee drinkers (at least one cup per day for the past five years) and had no history of complete caffeine avoidance. The study was open-label, meaning participants were aware of which group they were assigned to.
Researchers carefully monitored all volunteers using wearable electrocardiogram (EKG) monitors and implanted devices.

Coffee Appears Safe, and Potentially Protective
The results showed that participants who continued to drink coffee experienced a significantly lower risk of atrial fibrillation recurrence – 39% lower – compared to those who abstained. Specifically, arrhythmia returned in only 47% of the coffee-drinking group, compared to 64% in the non-coffee group. This finding directly contradicts decades of medical advice suggesting coffee triggers or worsens arrhythmia.
Researchers are exploring potential mechanisms behind this protective effect. It appears coffee may increase physical activity, which can suppress heart arrhythmias. Caffeine’s diuretic properties may also contribute by lowering blood pressure.
Coffee Consumption: Proceed with Moderation
Researchers caution that while the study suggests a potential benefit, moderation is key. The findings do not negate the importance of a healthy lifestyle, including a balanced diet and regular exercise. The study also suggests that caffeine may block certain adenosine receptors, which contribute to irregular heart rhythms.
According to the American Heart Association, more than 10 million people in the United States alone live with atrial fibrillation. The condition can often be asymptomatic, but frequently causes palpitations, dizziness, and fatigue. In severe cases, it can lead to blood clot formation and stroke.
The study’s findings are particularly noteworthy given the widespread perception of coffee as a potential risk factor for heart health. The results suggest that a common beverage may, in fact, offer a natural form of protection.
