According to a recent phase II NOVA study, using botulinum toxin type A in cardiac surgery patients does not reduce the risk of atrial fibrillation overall, but may have some benefit in certain subgroups. Although postoperative AF affects one to two-thirds of patients after cardiac surgery, there is not a standard treatment for it. This study, while small, is a promising start in the effort to find effective treatment.
