Regular coffee consumption does not trigger increased heart rates, according to the largest study on coffee and cardiac health.
The study, which measured the chronic consumption of caffeinated products over a 12-month period, is the largest study to date to have evaluated dietary patterns in relation to extra heartbeats.
The research dispels earlier studies that warned caffeine consumption could cause interruption to regular cardiac rhythms.
University of California San Francisco researchers said contrary to current clinical belief, regular caffeine consumption does not lead to extra heartbeats that have been linked to heart-or stroke-related morbidity and mortality.
“Clinical recommendations advising against the regular consumption of caffeinated products to prevent disturbances of the heart’s cardiac rhythm should be reconsidered, as we may unnecessarily be discouraging consumption of items like chocolate, coffee and tea that might actually have cardiovascular benefits,” senior author Gregory Marchus said.
The study was published in the January 2016 issue of the Journal of the American Heart Association.
