ABSTRACT
Serum cardiac troponin-T was measured to evaluate perioperative myocardial injury in heart surgery. Twelve patients of coronary artery bypass graft (CABG) and nine of mitral valve replacement (MVR) were selected and the measurements were performed at 3 points-before, as well as after the surgery and on the first postoperative day. Elevated serum levels of troponin-T were observed in postoperative measurement in both groups (CABG 2.98 +/- 1.44, MVR 2.57 +/- 0.52 ng.ml-1), where all the preoperative values were less than 0.1 ng.ml-1. On the first postoperative day, CABG group showed a higher serum level of troponin-T than MVR group (6.05 +/- 4.16 vs. 2.57 +/- 2.12 ng.ml-1, P < 0.05 respectively). Taking another myocardial marker, such as CK-MB or myosin light chain I, into consideration, these data indicate that myocardial injury occurs during heart surgery and the grade of injury is severer in CABG than in MVR.
