Prophylaxis for Patients at Risk to Eliminate Post-operative Atrial Fibrillation

After surgery on the lungs or esophagus, 12-46% of patients experience an irregular heart rhythm called atrial fibrillation. Although usually transient, post-operative atrial fibrillation is associated with longer stay in hospital, greater complications, and increased risk of death. Several medications have been shown to be effective at reducing the risk of atrial fibrillation after their surgery with the greatest effectiveness and safety demonstrated with amiodarone. Nevertheless, amiodarone has potential side effects, and so it is only recommended in patients with increased risk of developing atrial fibrillation. A tool has been developed and validated to identify high-risk patients but no clinical trial has looked at the effectiveness of administering amiodarone in this high-risk group. This study aims to assess the feasibility and safety of conducting a clinical trial where patients are randomized to receive amiodarone or placebo. This is critical before considering a full-scale trial to assess the effectiveness of amiodarone in reducing atrial fibrillation after surgery on the lungs or esophagus.
