Effect of Prophylaxy of Amiodarone and Propranolol and Amiodarone With Propranolol in Prevention of Atrial Fibrillation Post Coronary Artery Bypass Graft

Effect of Prophylaxy of Amiodarone and Propranolol and Amiodarone With Propranolol in Prevention of Atrial Fibrillation Post Coronary Artery Bypass Graft, A Prospective Double-Blind Randomized Study

Atrial fibrillation is the most common arrhythmia post coronary bypass surgery, currently B-blockers are the class I indication to prevent AF post CABG. We decide to evaluate use of propranolol and amiodarone separately and together to find a better prophylaxis for AF peri-CABG

In this double blind randomized study 240 consecutive patients underwent elective coronary artery bypass grafting, being randomized prospectively into three groups, propranolol (p) (n=80), amiodarone (A) (n=80) and amiodarone with propranolol (AP) (n=80).

All groups received their medications from 7 days preoperatively and continued their medications for 5 days post CABG.

Inclusion Criteria:

• Patient who are going to have elective CABG
• Signing informed consent

Exclusion Criteria:

• EF<35%
• Bradycardia<60 per min
• Hypotension< 100 mmhg
