The use of N-terminal pro-brain natriuretic peptide as a predictor of atrial fibrillation after cardiac surgery.

Aim: Atrial fibrillation (AF) is the most common arrhythmia after cardiac surgery with cardiopulmonary bypass (CPB). The value of Nt-pro BNP in predicting AF complicating cardiac surgery is not well studied. Our objective is to determine its predictive role in the occurrence of this complication after heart surgery with cardiopulmonary bypass.
