[Differential diagnosis between skeletal muscle lesions and myocardial damage in multiple injury by determination of myocardial-specific creatine phosphokinase (CK-MB) (author's transl)].

The serum level of the myocardial-specific isoenzyme of creatine phosphokinase, CK-MB was determined in 50 patients with severe multiple injuries or following extensive surgery. It is concluded that whenever the proportion of CK-MB exceeds 10% of the total creatine phosphokinase activity myocardial damage has occurred, especially since equivalent ECG changes were registered in this group of patients.
