Koffein scheint das Gegenteil von dem zu bewirken, was Sie vielleicht denken, wenn es um das Herz geht. Wissenschaftler haben herausgefunden, dass eine Tasse Kaffee am Tag das Herz tatsächlich vor Vorhofflimmern schützt – einem Zustand, der zu Schlaganfall und Herzversagen führen kann.

I’ve linked to the news release in the post above. In this comment, for those interested, here’s the link to the peer reviewed journal article:

From the linked article:
Coffee has „astounding“ impact on irregular heartbeat in world-first trial
**Caffeine appears to do the opposite of what you might think when it comes to the heart. Scientists have found that a cup of coffee a day actually protects the heart from atrial fibrillation – a condition that can lead to stroke and heart failure.**
The results were astounding,“ said first author Professor Christopher X. Wong from the University of Adelaide and Royal Adelaide Hospital. „In contrast to conventional wisdom, we found the coffee drinkers experienced a significant reduction in AF compared to those who avoided coffee and caffeine.
“This is surprising as it goes against the common assumption by doctors and patients that coffee worsens heart rhythm disorders such as AF,“ he added. „Doctors have always recommended patients with problematic AF minimize their coffee intake, but this trial suggests that coffee is not only safe but likely to be protective.”
In the DECAF (Does Eliminating Coffee Avoid Fibrillation) trial, the researchers found that caffeine resulted in a 39% lower risk of recurrent AF events, compared to those who abstained – and they have a few theories as to why this might be the case.
“Coffee increases physical activity which is known to reduce AF,“ said senior author Professor Gregory Marcus from the Division of Cardiology at UCSF. „Caffeine is also a diuretic which could potentially reduce blood pressure and in turn lessen AF risk. Several other ingredients in coffee also have anti-inflammatory properties that could have positive effects.“
Oh sweet.
So caffeine is GOOD for the heart now?
Im going to fish those 6 monsters that I threw out from the trash.
I hate these „discoveries“ that are basically the common sense middle ground of „some“ being better than „none“ or „far too much“

„coffee or an espresso shot“– it is not explicitly caffeine.
Coffee and espresso have many polyphenols in it that we already know have many beneficial effects. To say „caffeine“ as the direct relation here is a misstep.
‚In the DECAF (Does Eliminating Coffee Avoid Fibrillation) trial, the researchers found that caffeine resulted in a 39% lower risk of recurrent AF events, compared to those who abstained – and they have a few theories as to why this might be the case.‘
Again, this does not account for polyphenols in coffee…
Dosage is an important consideration. A large proportion of coffee drinkers don’t limit themselves to just one cup a day. To get a better assessment, you need to investigate some sort of dose response.
This is the second study I’ve heard of with this theory. Yet, in my actual life, caffeine has only really bad effects on my AF.
Just went through heart surgery, had a cup of coffee after 12 weeks and had atrial fibrillation for three days after.
