A small (60 patient) study conducted on people who have undergone heart bypass surgery yielded impressive results. Atrial fibrillation is a often an agitating complication of heart bypass surgery that can cause serious consequences to health and finances.

In this blinded randomized control trial, patients who received botulinum toxin injections into the heart during surgery had a 7% chance of developing atrial fibrillation in comparison to a 30% chance in those who received saline injections. More impressively, one year after surgery, none of the patients who received Botox had atrial fibrillation compared to 27% in the saline group.

A positive find, but a need for a larger, more comprehensive study is welcomed.
