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...

Growing coffee contributes to “climate change”. Greta would not be happy.
As Glenn Reynold of Instapundit fame would say: coffee, what can it not do? He literally has been saying this for decades.
Coffee, is there anything it can’t do!
Not taste like brake fluid to me.
Coffee is enjoyable, which is why Leftists hate it.
Along with heterosexual sex in marriage, a hot shower, and a good dog and cat (not all at the same time, unless you’re into that).
They despise humanity, God, and the simple pleasures God gives us.
You know what brake fluid taste like?
(Also: I’m addicted to drinking brake fluid. But I can stop at any time.)
Yes, but I have been trying to cut back a little bit anyway.
(I’m down to two pots a day now.)
What will tomorrow’s study say about coffee? 😵💫
Good grief. Causes afib. Cures afib. May cause, may cure! Make up your mind
Let’s see...
1 cup decreases the chance of Afib by 39%.
2 cups by 80%
3 cups a day should have me sitting pretty!
Who was the Artful Doger’s compadre?
Master Bates I believe
have you tried any of the different way coffee is prepared?
Some barely even have the signature coffee taste and creates an entirely different flavor profile.
Hmm, well designed study. Participants had AFib and were required to drink coffee. AFib is also common in advanced/elite athletes in sports with a significant endurance component. None of the people I know with AFib are overweight; all were exceptionally fit.
But maybe those coffee beans that have been pooped out of that animal that eats them, then collected and used to make coffee is good for the environment! Greta can have my share! BTW, I come from an area of the country that is loaded with Swedes; they are huge coffee drinkers.
Combined with eggs, the coffee cocktail may be the next method of execution for capital crimes.
I’m still amused by how they define a “cup” of coffee.
It’s not 8 ounces. It’s more like 5.
Coffee can’t wash a sink full of dishes for you!
Just think what a coffee enema would do!
Everything in moderation. A cup of coffee each day is a nice way to start the day. Matching a cup of coffee with a half hour of quiet time and prayer while I look out the window at the rising sun is effective meditation and brings peace of mind.
