  1. Patients who died from an acute MI were given a score of 4. *For CABG-related MIs, the peak value during the first 24 h after surgery was also used, as was the mean of a ratio between the peak values during the first 24 h to the laboratory upper limit of normal. ULN, upper limit of normal of local laboratories for the CK-MB values.
