Why the study?
Does serial measurement of cardiac troponin I (cTnI) diagnose perioperative myocardial infarction in patients undergoing coronary artery bypass grafting?
Does serial measurement of cardiac troponin I (cTnI) diagnose perioperative myocardial infarction in patients undergoing coronary artery bypass grafting?
Specific cutoffs of cardiac troponin I at 12 and 24 hours post-surgery can diagnose perioperative myocardial infarction with high probability in patients undergoing elective CABG.
No takes yet. Share an insight, caveat, or question.
These cTnI thresholds may aid perioperative MI diagnosis after CABG; leaves open prospective validation before practice change.
Mair et al. (1994) studied this question.
