Abstract

Heart failure (HF) has high morbidity and mortality in children. This study aimed to investigate the value of cardiac myosin binding protein-C (cMyBP-C) as a diagnostic and prognostic biomarker in children with heart failure. This study was a prospective case–control study that involved 50 children with acute HF and 25 healthy children of matched age and sex as a control group. cMyBP-C plasma levels were measured in patients with HF at the time of admission and 1 month after treatment. Echocardiographic assessment was done for all children. All patients were followed up for a period of 3 months. There was a significant increase in plasma levels of cMyBP-C (ng/ml) in patients with HF at admission (122.44 ± 41.01) as compared to patients after treatment (71.38 ± 49.68) and to control group (24.40 ± 9.83). This increase was associated with increased severity of HF according to pediatric Ross classification of HF. Significant increase in plasma levels of cMyBP-C at admission and its persistent increase after treatment were associated with adverse outcome of mortality and readmission. Plasma levels of cMyBP-C were significantly correlated with echocardiographic and clinical assessment of heart failure. Plasma levels of cMyBP-C were a good biomarker for diagnosis of HF with sensitivity 100% and specificity 96% at cutoff point of 45 ng/ml. Its value in predicting adverse outcome in HF patients was obtained by ROC curve with sensitivity of 90% and specificity 93% at a cutoff point of 152 ng/ml cMyBP-C at admission. cMyBP-C may be a novel useful diagnostic and prognostic biomarker in children with heart failure and determination of severity of HF in these patients.
