Abstract
Monitoring of cardiospecific markers is significant during intensive care.The objective: to compare the diagnostic and prognostic significance of cardiac markers in newborns with somatic and surgical pathology.Subjects and Methods. The study included 76 newborns aged 1 to 14 days with somatic or surgical disorders. The changes in the concentration of cardiomarkers in newborns and their relationship with echocardiography data and non-invasive hemodynamic parameters are presented, their prognostic ability is assessed.Results. Rigidity of non-invasive hemodynamic parameters, and echocardiography data was revealed. In the somatic group, regression of NT-proBNP from 8,307 ng/ml (3,600; 9,000) to 1,717 ng/ml (1,041; 5,011) was regarded as a marker of resolution of hypervolemia against the background of cardiovascular maladaptation. The increase in NT-proBNP from 4,710 ng/ml (3,400; 6,989) to 7,987 ng/ml (3,397; 9,000) in the postoperative period requires a revision of the infusion therapy program with the priority of volume restriction.Conclusions. Stabilization of the condition of patients in the groups is accompanied by a decrease in the concentration of markers of myocardial tension (MB-fraction of creatine phosphokinase, troponin T).Measurement of NT-proBNP concentration allows assessment of fluid overload in critically ill neonates.
