Troponin I, Troponin T, or Creatine Kinase-MB to Detect Perioperative Myocardial Damage After Coronary Artery Bypass Surgery: Conclusion

Early postoperative ventricular dysfunction, as observed with echocardiography, is more likely to occur because of reversible myocardial stunning during aortic occlusion and reperfusion injury. Creatine kinase (CK) and CKMB are often used with no clear threshold. In this study, it would have been inappropriate to use CK or CKMB, a cytosolic marker, to study the […]

Troponin I, Troponin T, or Creatine Kinase-MB to Detect Perioperative Myocardial Damage After Coronary Artery Bypass Surgery: Discussion

The main findings of our study were that (1) in noncomplicated postoperative CABG, cTnl values remained constantly low, contrasting with very high values when perioperative myocardial infarction occurred, and (2) there was little difference between cTnl, cTnT, and CKMB to diagnose myocardial damage after CABG as assessed by the appearance of new Q wave on […]

Troponin I, Troponin T, or Creatine Kinase-MB to Detect Perioperative Myocardial Damage After Coronary Artery Bypass Surgery: Materials and Methods

Blood Sampling Serial venous blood samples were obtained immediately before anesthesia induction, before aortic declamping (0), and 6, 12, 24, and 48 h after aortic declamping. Plasma samples were stored at — 70°C after centrifugation and processed in the month following collection for measurements of CKMB mass, cTnl, and cTnT. Analytical Methods cTnl was measured […]
