MedicalResearch.com: What is the background for this study? What are the main findings?
Response: The autonomic nervous system activity plays an important role in the onset and perpetuation of atrial fibrillation, particularly for AF that follows cardiac surgery.
Botulinum toxin (BTX) is a potent inhibitor of neural transmission. In a randomized placebo-controlled study of 60 patients undergoing coronary artery bypass graft surgery, patients who received intraoperative Botulinum toxin injections to the neural ganglia on the cardiac surface exhibited a sustained reduction in the incidence and overall burden of atrial fibrillation (AF) over 3 years of follow-up, accompanied by a reduction in need for hospitalization.
