Botulinum toxin shows promise in trials to reduce post-operative atrial fibrillation (POAF) in cardiac surgery patients

Postoperative atrial fibrillation (POAF) is a common complication, affecting one quarter to one half of all patients following cardiac surgery. It can result in heart failure, stroke, and longer hospital stays, resulting in an increased cost of care. A new study reports promising results from two clinical trials using botulinum toxin (BTX) injections to suppress POAF.
