[Dynamics of a necrotic focus development based on data from determining the activity of the MB CPK fraction and from precardiac mapping].

In the 26 patients dead during the acute (necrotic) period of the disease comparisons in the changes of activity of MB CPK and the data of the precardial charting with the results of the histological analysis of the hearts is made. The histological analysis served to assess the date of the necrosis in different areas of the heart. It is established that the repeated rises of activity of MB CPK and the increase in the number of the complexes QS are determined by the development of new foci of necrosis.
