[Automatic method for the evaluation of the extent of myocardial infarct from the serum of CPK curve].

An off-line system for calculating the extent of infarct from serial serum CPK determinations based on Sobel et al.'s compartmental model is presented. Results in 40 patients with acute infarct in a coronary unit showed that the index of infarct extent had an appreciable prognostic significance. Employment of the MB isoenzyme in the calculation could, it is felt improve the sensitivity of the method.
