Caffeine: No Downside, Hint of Benefit in Atrial Fibrillation
A meta-analysis from Chinese researchers has concluded that there is an inverse relationship between regular caffeine consumption and atrial fibrillation risk.
“It is unlikely that habitual caffeine intake increases AF risk,” write Dr Min Cheng (State Key Laboratory of Cardiovascular Disease, Beijing, China) and colleagues in their study, published online January 6, 2014 in the Canadian Journal of Cardiology.
In fact, they conclude, habitual caffeine consumption may actually reduce AF risk.
“The finding of this study is meaningful. First, there is no need for concern that habitual caffeine intake may increase AF risk. Second, as atrial fibrosis is an important substrate for AF and caffeine has an antifibrosis property, the finding may pave the way for seeking effective antifibrosis agents for AF management or prompt development of caffeine as an agent for preventing AF,” Cheng et al write.
