[Changes in the activity of cytoplasmic enzymes and myoglobin in muscle cells of postinfarction aneurysm of the human myocardium].

Enzymatic sprectra were studied in myocytes of human heart aneurysm as compared with the muscle cells of intact myocardium. Activities of G-6-PDH and AK as well as content of myoglobin were increased. Activity of the other enzymes studied (CPK, AsAT, IDH, MDH, LDH, PPK) was unaltered. Alterations, specific only for the muscle cells, were detected using a new calculation technique--comparison of relative (based on creatine) concentrations of myoglobin and the enzymatic activities in aneurysm and intact myocardium.
