In 397 cases, serum glutamic oxaloacetic transaminase (GOT) and creatine phosphokinase (CPK) values were determined on the first, second, and third days after aorta-coronary artery saphenous vein bypass graft operations. Electrocardiographs (ECG) or vectorcardiographic (VCG) evidence of postoperative transmural infarction was found in 48 cases. Multivariate analysis indicated that GOT and CPK concentrations on Day 1 had substantial discriminatory value regarding infarction. Discrimination by GOT alone was not significantly improved by addition of CPK. Of the 61 cases positive by GOT values measured 1 day postoperatively (> 100 U. per liter; normal < 24), 32 (52 per cent) were negative by ECG or VCG; of the 336 cases negative by GOT, 19 (6 per cent) were positive by ECG or VCG. GOT and CPK values increased with the number of vessels grafted and with the use of ventricular rather than atrial vents. Total serum enzyme values lack specificity in diagnosis of transmural infarction after the saphenous vein bypass operation. |
