Heart failure is the most common complication of congenital heart disease (CHD), characterized by high morbidity and mortality. Early recognition and intervention are crucial for improving outcomes in pediatric patients with CHD and heart failure. This study aimed to analyze the clinical value of N-terminal pro-brain natriuretic peptide, adrenomedullin, and cardiac troponin I in pediatric patients with CHD and heart failure.
Ninety-eight pediatric patients with CHD complicated by heart failure were included in the Case Group, and 61 pediatric patients with CHD were included in the Control Group. The Case Group was categorized into subgroups based on the cardiac function of patients: grade I (n = 35), grade II (n = 40), and grade III (n = 23). Left ventricular ejection fraction was collected from pediatric patients in the case group. The correlation of the cardiac functional indicators with N-terminal pro-brain natriuretic peptide, adrenomedullin, and cardiac troponin I levels was assessed using Pearson correlation analysis.
The serum levels of N-terminal pro-brain natriuretic peptide, adrenomedullin, and cardiac troponin I in pediatric patients at grade III of cardiac function were significantly elevated compared to those at grade II, and these levels in patients at grade II were higher than those at grade I (P < 0.05). The left ventricular ejection fraction of pediatric patients in the Case Group were markedly negatively correlated with N-terminal pro-brain natriuretic peptide, adrenomedullin, and cardiac troponin I (r = − 0.6807, r = −0.3013, r = −0.5412, P < 0.0001).
N-terminal pro-brain natriuretic peptide, adrenomedullin, and cardiac troponin I have a certain diagnostic value in determining concurrent heart failure in pediatric patients with CHD.
