Surprising heart study finds daily coffee may cut AFib risk by 39%
Science Daily ^ | November 10, 2025 | Science Daily

New research suggests that drinking coffee may actually help protect against atrial fibrillation (AFib), a common heart rhythm disorder that causes the heart to beat too quickly and irregularly, sometimes leading to stroke or heart failure.

For years, doctors have advised people with AFib and other heart issues to stay away from caffeine, fearing it could worsen symptoms. But a new study from UC San Francisco and the University of Adelaide has found the opposite: participants who drank one cup of caffeinated coffee a day had a 39% lower risk of developing AFib.

Why Coffee May Help the Heart

"Coffee increases physical activity which is known to reduce atrial fibrillation," explained Gregory M. Marcus, MD, MAS, an electrophysiologist at UCSF Health and the senior author of the study, published November 9 in JAMA. Marcus added that "caffeine is also a diuretic, which could potentially reduce blood pressure and in turn lessen AFib risk. Several other ingredients in coffee also have anti-inflammatory properties that could have positive effects."

Rates of AFib have been climbing in recent years, largely due to aging populations and increasing obesity. More than 10 million adults in the United States have been diagnosed, and experts estimate that as many as one in three people may experience the condition at some point in their lives.

Testing Coffee's Effect on Heart Rhythm

To explore whether coffee helps or harms, researchers designed the DECAF study (Does Eliminating Coffee Avoid Fibrillation?), the first randomized clinical trial to test the relationship between caffeinated coffee and AFib. The project was funded by the National Institutes of Health.

The trial involved 200 patients who were regular coffee drinkers and had persistent AFib or a related condition known as atrial flutter...

Do you imbibe in break fluid often? Straight or mix it with antifreeze?

I get mad because sometimes the coffee blocks the taste of the included fireball whiskey.

While the specific “oldest person” who still drinks coffee changes, Richard Overton, America’s oldest World War II veteran, was widely reported to still be drinking coffee at age 112 in 2018. Many centenarians and supercentenarians consume coffee regularly as part of their diet, sometimes alongside other habits like smoking cigars or drinking whiskey.

Regardless of how true this is I wouldn’t want to live in a world without coffee. It is one of God’s great gifts to us.

totally bogus study ...

“At the end of the study, the group that drank coffee experienced a 39% lower risk of recurring AFib episodes.”

most likely what the study discovered is that those whose Afib was triggered by coffee continued to drink it, and those who were Afib-sensitive to it stopped drinking it... there are many triggers for Afib, and they are different for different people ....

And once or twice a week, drop a clove into your coffee to boost your immune system. Don’t eat the clove.

And I recently heard that 4 cups of black coffee helps fatty liver disease. Assists the liver in clearing itself. I think I’ll go have another cup...

They despise humanity, God, and the simple pleasures God gives us.

They love the simple pleasures God gives us.

After they are perverted of course.

I had both afib and flutter and my electrophwhatist said lay off the coffee.

Chocolate, too, the heretic!!

So, I just got the operation. A year ago, no recurrence.

The alternative was death — since the drugs that work on Afib don’t on flutter.

I prefer to add a bit of whisky to my coffee every now and then to kill the germs in my mug before they ever reach me ;)
