Botox: An Rx for Irregular Heartbeat After Cardiac Surgery? - (U.S. News & World via NewsPoints Desk)

  • Study data presented at the Heart Rhythm Society annual meeting suggest that Botox can be used to correct an irregular heartbeat after cardiac surgery, as reported US News & World Report.
  • In the study, the researchers treated 60 patients with a history of atrial fibrillation with a single injection of Botox or placebo in the heart during surgery.
  • The investigators found that 7 percent of patients in the Botox arm developed atrial fibrillation between one week and three weeks after surgery, compared to 30 percent of placebo-treated patients.
  • The resaerhcers additionally observed that 11 percent of patients in the placebo group experienced recurring bouts of atrial fibrillation during the 11 months after surgery, versus no patients in the Botox group.
  • "Of course, we need to continue to look at this with a wider, bigger study that has more patients," remarked study author Evgeny Pokushalov, adding "but the data we already have is good. And it could lead to a big change for how we handle patients who undergo open-heart surgery."
  • "We might also be able to use this technology following any type of invasive surgery," Pokushalov noted, continuing "and also for patients who don't undergo surgery at all but are at a high risk for atrial fibrillation. This is something we are looking into in the future."
