Simultaneous occurrence of the MB isoenzyme of creatine kinase and macro creatine kinase type 1 in a patient with acute myocardial infarction.
When the immunoinhibition method is used for differentiation of isoenzymes of creatine kinase, the simultaneous occurrence of the MB isoenzyme and variants of macro creatine kinase may lead to misinterpretation in the diagnosis of acute myocardial infarction. We describe the case of an elderly woman in whom the MB isoenzyme and the type 1 variant of macro creatine kinase were found simultaneously in her serum after acute myocardial infarction. It proved possible to identify the MB isoenzyme rapidly using a fast enzymeimmunoassay.
