[Kinetics of myoglobin, creatine kinase and aspartate aminotransferase in uncomplicated and complicated forms of healing of experimental myocardial infarction].

It was demonstrated in experiments on 60 dogs that in hyporeactive myocardial infarction (MI) myoglobin (MG) concentration and the activity of creatine kinase (CK) and aspartate aminotransferase (ASAT) increase at a slower rate and reach maximum values later. In hyperreactive MI the rate of their increase and the time of attainment of maximum values are, respectively, greater and earlier than in normoreactive MI. The connection of MG, CK, and ASAT changes with reactivity allows them to be used in prognosticating MI healing.
