title: [Chronic high levels of CK-MB].
abstract: We presented two cases of falsely elevated CK-MB due to the presence of a type 2 macro CK, showed by isoenzymes electrophoresis. The association of this CK-MB falsely elevated with some digestive diseases are frequent. Quantification of CK isoenzymes by electrophoresis could be indicated in those cases in which the clinical course or ECG changes do not correlate with the CK-MB values.
