Fig. 1. Cardiac troponin I (cTnI) time profiles since arrival at the intensive care unit in the early (EPMI) or delayed (DPMI) postoperative myocardial infarction and myocardial damage (MD) groups. (  A ) Time to detection of first abnormal cTnI value. (  B ) Time to postoperative myocardial infraction (cTnI value ≥ 1.5 ng/ml). (  C ) Time to peak cTnI concentration.
