Influence of mammary artery as a bypass vessel on the results of seven biochemical assays after coronary artery bypass surgery.
We compared the changes in troponin T, creatine MB isoenzyme mass concentration (CK-MB mass), creatine kinase MB isoenzyme activity (CK-MB activity), creatine kinase (CK), alpha-hydroxybutyrate dehydrogenase (HBD), lactate dehydrogenase (LD) and aspartate aminotransferase (AST) concentrations after coronary artery grafting with saphenous vein grafts, without or in combination with uni- or bilateral internal mammary artery(ies) as bypass vessels in 73 patients. An increase in CK concentration after surgery was highest for the bilateral internal mammary artery bypass patient group and lowest for the group who received only saphenous vein grafts. We present 90th percentile values for the seven tests.
