The Journal of the American Medical Association on Sunday published those findings, which were also presented at the American Heart Association conference in New Orleans."
"Marcus and his collaborators wrote that they used tools, such as electrocardiograms taken at doctors' offices and wearable monitors, to determine if and when participants had an irregular heartbeat. They ultimately determined that participants who drank coffee were 17% less likely to have a recurrence of an irregular heartbeat during the trial and went longer before they had their first instance of one amid the study."
Two hundred patients with persistent atrial fibrillation were enrolled in a six-month randomized clinical trial named Decaf. Participants were older adults from the US, Canada and Australia who had regularly consumed coffee in the previous five years. Random assignment placed participants into a caffeine-abstention group or a group consuming at least one cup daily, with intake self-reported during intermittent video checkups. Electrocardiograms and wearable monitors were used to detect irregular heartbeats and timing of recurrences. Coffee-consuming participants experienced a lower recurrence rate (47% vs 64%), a 17% reduced likelihood of recurrence, and a longer time to first recurrence.
