Long-held standard medical advice has been that if you have any sort of risk of developing an irregular heart rhythm such as atrial fibrillation, for example, or indeed if you already have some sort of rhythm abnormality (in your heart rate, I mean, not like a rhythm irregularity in which you can’t dance), then you must avoid coffee because, well, because coffee will both bring on an irregular heart rhythm and even more assuredly, worsen an already-established irregularity.
Well, maybe not.
According to a large just-released study, “caffeine doesn’t seem to increase most people’s risk of arrhythmias”.
In fact, in this study, coffee drinkers actually had a slightly reduced risk of developing a cardiac rhythm abnormality.
As the authors put it: “There could be some individuals where caffeine is their trigger, but I think the growing evidence is those cases are actually quite rare.”
“The majority of people, even those with arrhythmias, should be able to enjoy their cup of coffee, and maybe there are some people for whom caffeine or coffee may actually help reduce their risk.”
Words to celebrate with a double cappuccino, I suggest.
