More than 10 million Americans live with atrial fibrillation, or A-fib, a common heart disorder that causes heart palpitations and can lead to heart failure, blood clots and stroke.
AI Summary
Main Idea: A new trial found that drinking one cup of caffeinated coffee a day may be safe for people with atrial fibrillation and could lower the chance the heart rhythm problem comes back.
Key Points:
- The study followed 200 adults with a history of atrial fibrillation, also called A-fib, for six months.
- People who drank at least one cup of coffee a day had fewer repeat episodes than those who cut out caffeine.
- The trial suggests coffee may not trigger A-fib for many people, but results may not apply to everyone.
- Doctors said moderation matters, and some people may still feel worse with caffeine, especially during an active episode.
Impact on the People
Negative Impact
No clear negative impact identified.
Positive Impact
People with atrial fibrillation may not need to avoid one cup of coffee a day, which could reduce worry and improve daily routines. The study was small, so doctors may still advise caution for some patients.
