Mass concentration and activity concentration of creatine kinase isoenzyme MB compared in serum after acute myocardial infarction.
We compared three current methods (immunoinhibition, "Isomune-CK" immunoprecipitation, and the Tandem-E CKMB II immunoenzymometric assay) for determination of creatine kinase (CK; EC 2.7.3.2) isoenzyme MB in serum. Although results inter-correlated well, the immunoinhibition assay gave higher activity values. Atypical CK forms did not interfere with the immunoprecipitation and immunoenzymometri...
متن کاملActivity concentration and mass concentration (monoclonal antibody immunoenzymometric method) compared for creatine kinase MB isoenzyme in serum.
Results of the "Tandem-E CKMB" immunoenzymometric procedure (y) for creatine kinase (CK; EC 2.9.3.2) were compared with electrophoresis (x) for 160 serum samples from patients suspected of having sustained myocardial infarctions. The results correlated well: y, microgram/L (Tandem assay) = 1.3x-6.3 U/L(electrophoresis) (r = 0.95). CK-MB mass measurement was more stable than enzyme activity afte...
متن کاملCreatine kinase isoenzyme MB in myocardial infarction: methods compared.
Several methods are available for specifically identifying and assessing the activity of MB isoenzyme of creatine kinase in serum. We compared two electrophoretic techniques with three column-chromatographic ones for efficacy in the diagnosis of myocardial infarction. No technique was considered absolute, but we found surprisingly large errors of diagnosis in the column-chromatographic techniqu...
متن کاملContribution of creatine kinase MB mass concentration at admission to early diagnosis of acute myocardial infarction.
OBJECTIVE To assess the diagnostic value at admission of creatine kinase MB mass concentration, alone or in combination with electrocardiographic changes, in suspected myocardial infarction. DESIGN Prospective study of all consecutive patients admitted within 12 hours after onset of chest pain to a coronary care unit for evaluation of suspected myocardial infarction. SETTING Large regional ...
متن کاملComparison of serum myoglobin and creatine kinase MB isoenzyme in early diagnosis of acute myocardial infarction.
We compared the clinical usefulness of serum myoglobin and creatine kinase MB (CK MB) isoenzyme determinations in the early diagnosis of acute myocardial infarction in 109 consecutive patients admitted to a coronary care unit. Of these, 37 patients were diagnosed as having definite infarction, three possible infarction, and 69 no infarction, using World Heath Organisation criteria. Blood sample...
