OBJECTIVEThe aim of the study was to evaluate the condition of the cardiovascular system and the effect of the combined preparation of magnesium and vitamin B6 in children with secondary cardiomyopathy on the background of chronic tonsillitis.PATIENTS AND METHODSMaterials and methods: 100 children at the aged of 13-17 years were surveyed, including 60 patients with secondary cardiomyopathy with chronic tonsillitis. And the group I consisted of 45 children receiving standard treatment, group II - 15 patients who, along with standard treatment, received the drug magnesium. The control group consisted of 40 healthy children. To assess the condition of the cardiovascular system and vegetative regulation, we performed electrocardiographic examination (ECG), exercise test and ECG control, cardiointervalography with clinoortostatic test. The concentration of magnesium in the serum was determined by atomic absorption spectrophotometry. Also, we have provided the requirements of the principles of bioethics and drafted a protocol in accordance with the basic principles of the Helsinki Declaration.RESULTSResults: In addition to the standard treatment of children with magnesium drug, there was a significant decrease in the frequency of sinus arrhythmias, disorders of the intraventricular conduction, and the processes of repolarization, extrasystole, sinus suchchardia were not observed in any of the patients. The normalization of magnesium in the serum of patients was observed.CONCLUSIONConclusions: Supplementation of combination therapy with magnesium and B6 helped to improve myocardial electrophysiology and cardiac output, as well as to normalize the serum magnesium in children with secondary cardiomyopathy.
