title: [Measurements of serum activity of creatine kinase and creatine kinase isoenzyme MB in suspected myocardial infarction. Experiences from a hospital material].
abstract: Total creatine kinase and the creatine kinase isoenzyme MB activities were measured simultaneously in 767 serum samples from 592 patients with suspected myocardial infarction. The main and obligate finding was that in the 89 patients with verified infarction the fraction of MB-activity related to the total creatine kinase activity lay between 4 and 25%. In 72 patients diagnosed as not-having an infarction this fraction tended to lie below 4%. However, false positives frequently occurred within the lower total creatine kinase activity range.
