[Isoenzyme diagnosis in the clinical course of acute myocarial infarct].

For the observation of the course of the disease of patients after an acute myocardial infarction by the estimation of the isoenzymes of the LDH (LDH-H and LDH-M) the possibility of the repeated four- to eight-hour-measurement of these isoenzymes in larger groups of patients after myocardial infarction is given. Instances of the use during the observation of the course of the disease after acute myocardial infarction are discussed. In which cases at the same time the isoenzymes of the LDH (LDH-H and LDH-M) as well as of the CK (CK-MB) were repeatedly estimated.
