But the new study which involved researchers in the University of Melbourne’s Baker Heart and Diabetes Institute along with partners in the United States consistently demonstrated a reduction in atrial fibrillation (irregular heartbeats) with increasing levels of caffeine ingestion.

The research analysed multiple population-based studies which involved 228,465 participants to find the frequency of atrial fibrillation decreased by 6 per cent in regular coffee drinkers, while a further analysis of 115,993 patients showed a risk reduction of 13 per cent.

“There is a public perception, often based on anecdotal experience, that caffeine is a common acute trigger for heart rhythm problems,’’ lead author Peter Kistler from the Baker Heart and Diabetes Institute said.

“Our extensive review of the medical literature suggests this is not the case.’’

“Caffeinated beverages such as coffee and tea may have long term anti-arrhythmic properties mediated by antioxidant effects and antagonism of adenosine,’’ Kistler concluded.
