FIELD: medicine.
SUBSTANCE: method involves measuring total magnetic resonant power TP, high-frequency value HF and examining creatine phosphokinase MB-fraction MB-CPK activity in blood serum. If the measured TP is from 3,600 to 1,635 ms2, HF is from 1,327 to 356 ms2, and the MB-CPK tends to increase from 24.7 to 55.5 units/l, cardiac function disadaptation is detected in healthy children. If the measured TP is from 1,377 to 168 ms2, HF is from 349 to 34 ms2, and the MB-CPK tends to increase from 56.7 to 139.5 units/l, diabetic cardiomyopathy is detected. The invention enables increasing the differential diagnostic of cardiac function disadaptation and diabetic cardiomyopathy in the children suffering subcompensated type I diabetes mellitus by the combined detection of the spectrographic TP, HF and MB-CPK in blood serum.
EFFECT: in as much as detecting MB-CPK ensures the high assessment of the cardiomyocytes and cell membranes, whereas detecting the BPC values makes it possible to mirror the myocardial power supply.
