well as laboratory hematologists provided specificity is also acceptable. But until such investigations are performed, such conclusions would be premature. Although the results of these studies are intriguing, they cannot yet be considered definitive. I hope that the group from Sweden and/or other investigators will pursue these leads. If the results are as anticipated, laboratories and manufac...
متن کاملCorrelation of antemortem serum creatine kinase, creatine kinase-MB, troponin I, and troponin T with cardiac pathology.
BACKGROUND Spurious increases in serum troponins, especially troponin T, have been reported in patients with and without acute myocardial syndromes. METHODS We studied 78 autopsied patients without clinical myocardial infarction (MI) and correlated histologic cardiac findings with antemortem serum creatine kinase (CK), its MB isoenzyme (CK-MB), cardiac troponin I (cTnI), and cardiac troponin ...
متن کاملCardiac troponin I, cardiac troponin T, and creatine kinase MB in dialysis patients without ischemic heart disease: evidence of cardiac troponin T expression in skeletal muscle.
Serum cardiac troponin T (cTnT) concentrations are frequently increased in chronic dialysis patients as measured by the first-generation ELISA immunoassay, as is creatine kinase (CK) MB mass in the absence of acute ischemic heart disease. We designed this study to compare four serum markers of myocardial injury [CK-MB mass, first-generation ELISA cTnT, second-generation Enzymun cTnT, and cardia...
متن کاملDifferences of creatine kinase MB and cardiac troponin I concentrations in normal and diseased human myocardium.
The diagnosis of myocardial infarction (MI) is established in patients with chest pain and equivocal electrocardiogram changes by demonstrating a rise in blood levels of creatine kinase MB (CK-MB) and/or an increase in cardiac troponin I (cTnI) or cardiac troponin T (cTnT). Previous studies have shown that levels of CK-MB are increased in the left ventricle of individuals with heart disease; ho...
متن کاملA comparison of cardiac troponin T and creatine kinase-MB for patient evaluation after cardiac surgery.
OBJECTIVES The aim of this study was to assess the role of serum markers of myocardial necrosis after cardiac surgery. BACKGROUND The role of serum troponin T (TnT) and creatine kinase-MB (CK-MB) for the risk stratification of patients after cardiac surgery remains undefined. METHODS Serum levels of TnT and CK-MB were measured from 224 patients every 8 h after cardiac surgery. The results o...
