Coffee Might Actually Protect Your Heart, New Study Finds

A groundbreaking study published in The Journal of the American Medical Association suggests that drinking coffee may help protect against irregular heartbeats, contradicting long-held medical advice.

The “Decaf” clinical trial followed 200 adults diagnosed with atrial fibrillation (A-fib), a condition affecting more than 10 million Americans.

Participants who continued drinking coffee were found to be 17% less likely to experience a recurrence of irregular heart rhythms compared to those who abstained.

Conducted across the U.S., Canada, and Australia, the six-month study used wearable monitors and electrocardiograms to track outcomes, with results presented at the American Heart Association conference in New Orleans.

While experts note limitations, including lifestyle differences and caffeine sources, cardiologists say the research could reshape how doctors advise patients.

For millions told to avoid caffeine, a daily cup of coffee might not just be safe — it could be beneficial.
