Effect of Remote Ischemic Preconditioning on Incidence of Atrial Fibrillation in Patients Undergoing Coronary Artery Bypass Graft Surgery

Atrial fibrillation is the most common arrhythmic complication after coronary artery bypass grafting (CABG). Post operative atrial fibrillation (POAF) increases morbidity and mortality. Inflammation could be a factor in POAF and recent evidence of remotely inducing ischemia may reduce inflammation and cardiac injury. The investigators plan to use a blood pressure cuff on the arm as a method to produce remote ischemia and assess the occurrence of POAF for seven day.
