This study addressed the question of whether oral intake of vitamin C can reduce the incidence of atrial fibrillation after on-pump coronary artery bypass grafting (CABG) surgery. One hundred patients were studied and divided into two groups. Group 1 received 2 g of oral vitamin C before surgery and 500 mg of vitamin C 2 times daily for up to 5 days after surgery. The other group received nothing. Results showed that participants in group 1 required significantly shorter hospital stays than study participants in group 2. The researchers concluded that vitamin C is a safe and effective agent for reducing postoperative atrial fibrillation after coronary artery bypass graft surgery. Further details can be found in the study.
