[Levels of troponin I, tropoinin T, isoenzyme MB creatine kinase and myoglobins in blood serum for perioperative diagnosis of myocardial infarction in patients after coronary artery bypass graft surgery with extracorporeal circulation].
Folia Med Cracov. 2001; 42(4):263-71.FM

Abstract

We studied plasma levels of troponin I (cTnI), troponin T (cTnT), creatine kinase MB (CKMBmass) and myoglobin (MB) in patients undergoing coronary artery bypass surgery with extracorporeal circulation and cardioplegia. In group 1 (25 patients without perioperative myocardial infarction) plasma levels of all markers studied were elevated after operation. In group 2 (24 patients with perioperative myocardial infarction) plasma concentrations of all markers exceeded several times levels observed in patients without myocardial infarction with maximal value for MB at 12 hours after operation; for cTnI and CKMBmass at 16 hours after surgery and for cTnT at 32 hours after the end of operation. ROC curves show cut-off value for CKMBmass 20.3 ng/ml (sensitivity 79% and specificity 89%); for cTnI cut-off value was 0.8 ng/ml (sensitivity 80% and specificity 94%) for cTnT the cut-off value was 0.41 ng/ml (sensitivity 86% and specificity 88%) and for MB the cut-off value was 419 ng/ml (sensitivity 85% and specificity 70%).

CONCLUSION

All markers studied are reliable biochemical tests for perioperative myocardial infarction, however, the analysis of ROC curves suggested that cTnI and cTnT might be more useful for diagnosis of perioperative myocardial infarction after conventional coronary artery bypass surgery.
