Comparative Study[Acute myocardial infarction diagnosis. The value of serum myoglobin levels, compared with creatine kinase MB fraction].
To compare the diagnostic performance of two traditional plasma markers of myocardial infarction (MI), creatine kinase (CK) and its MB fraction (CK-MB), with plasma myoglobin (Mgb) levels, for the diagnosis of MI. ⋯ In the studied population, Mgb was more sensitive than CK-MB for the diagnosis of MI with similar specificity and Mgb was more specific than CK for this diagnosis.
