[The significance of the radioimmunological of serum myoglobin in myocardial infarction].

The Authors carried on a study in a group of 31 patients with acute myocardial infarction (AMI). The controled particularly the following dates: myoglobinemia (MG) with RIA and myocardial necrosis enzymes with traditional methods. Blood has been drawn from patients every 90 min, during the first 8 h of admission and every 4 h during the following 4 days. Important variations of MG have been detected in 80.6% of cases. These is an early increase in MG (within 4 h in 25.8% and within 8 h in 45.1% of cases) and normal values are reached in a time not longer the 72 h. The maximum value is reached in a shorter time than that creatine phosphokinase (CPK). We can therefore confirm that MG is a useful data in the early diagnosis of myocardial infarction in preenzymatic stage.
