Open Access Abstract Introduction The objective of the present study was to compare postoperative cardiac troponin I cTnl release and the thresholds of cTnl that predict adverse outcome after elective coronary artery bypass graft CABG after valve surgery and after combined cardiac surgery. Methods Six hundred and seventy-five adult patients undergoing conventional cardiac surgery with cardiopulmonary bypass were retrospectively analyzed.
