"Drinking a daily cup of caffeinated coffee was linked to a 39% lower hazard of atrial fibrillation (a-fib) recurrence in older adults recently treated for the disorder, according to a study published in the Journal of the American Medical Association (JAMA). In practical terms, for roughly every six people who kept drinking coffee instead of quitting after a-fib treatment, one extra person avoided a recurrence, according to the findings."
"Led by researchers at both universities, the study represents the first randomized clinical trial investigating the link between caffeinated coffee and atrial fibrillation, a common heart rhythm disorder that causes rapid, irregular heartbeat and can lead to stroke and heart failure. A-fib has been diagnosed in more than 10 million U.S. adults and affects an estimated one in three people, according to the study authors."
A randomized clinical trial enrolled 200 adults with persistent atrial fibrillation or atrial flutter, most in their late 60s, all scheduled for electrical cardioversion. Participants had been coffee drinkers within the past five years and were randomized to either drink at least one cup of caffeinated coffee daily or avoid coffee and all other caffeinated drinks for six months after cardioversion. At six months, 64% of coffee abstainers experienced a recurrence versus 47% of coffee drinkers, corresponding to a 39% lower hazard of recurrence and an approximate number needed to treat of six.
