Perioperative Levels of Troponin and BNP and the Outcome after Coronary Artery Bypass Grafting.

Background: The independent predictive values of troponin I (cTnI) and B-type natriuretic peptide (BNP) after coronary artery bypass grafting (CABG) have been reported in several studies. However, adjustment only has been limited to preoperative risk factors.

Aim: This study was conducted to assess the independent values of postoperative cTnI and BNP to predict the outcome after CABG with adjustment for preoperative risk estimates and postoperative complications and to report risk stratification gains, when considering the European System for Cardiac Operative Risk Evaluation (EuroSCORE) combined with postoperative biomarkers.
