Background: The aim of this study was to provide insight into the interpretation of CK-MB data after major noncardiac surgery. Methods: Some 3321 patients who underwent major non-emergent noncardiac procedures (orthopedic 31%, intrathoracic 12%, vascular 22%, other 35%) were studied. All patients had at least two CK samples measured postoperatively. Results: Acute myocardial infarction was diagnosed in 43 (1.3%) patients using study criteria including CK-MB and electrocardiographic data. All of the various threshold values of peak CK-MB values and peak CK-MB as a percentage of total CK had poor positive predictive values because of high false positive rates and the low rate of acute myocardial infarction. Conclusion: These data demonstrate the need for markers of myocardial injury with greater cardiac specificity after noncardiac surgery.
