[Determining myoglobinemia in acute myocardial infarction by the immunoenzyme method]

Like radioimmunoassay, immunoenzyme assay permits detecting myoglobinemia both in healthy persons and in patients with acute myocardial infarction (AMI). In AMI patients, myoglobinemia reaches a maximum 5 to 12 hours since the onset of a powerful anginal attack whereupon it gradually and spasmodically decreases, without returning to normal toward outcome of the 3d day of the observation period. A single assay of myoglobinemia in AMI patients is of diagnostic importance within 2 to 27 hours since the disease onset.
