Troponin I may be more specific than CK-MB for perioperative MI after hip surgery; leaves open need for prospective validation before practice change.
Is troponin I more specific than CK-MB for detecting perioperative myocardial infarction in patients undergoing elective hip surgery?

Mouzopoulos et al. (2007) studied this question.
