[Retrospective evaluation of indicators of cardiospecific blood isoenzyme activity in patients with stenocardia and primary and recurrent myocardial infarction].

Comparatively moderate blood fermentemia (KPK, AST, KPK-MB and LDH1) exceeding the level of the statistic M + 1S index in the control group and lasting over 3 to 7 days can be viewed as one of the diagnostic criteria of the preinfarction state. The lack of the correlation between the enzymatic characteristics and the data on blood myoglobin concentration and precordial cartography readings (ECG 35 leads) makes the use of the latter two methods more preferable in the evaluation of the area of necrosis in patients with repeated myocardial infarctions and requires a more careful approach to the prognosis of complications in this patients' group.
