Clinical value of NT-proBNP measurements in assessing patients in the pediatric intensive care unit

BACKGROUND: N-terminal brain natriuretic peptide precursor (NT-proBNP) and brain natriuretic peptide (BNP) are mainly produced and secreted in the heart. In 2008, the European Heart Association recommended that serum BNP/NT-proBNP levels should be included in one of the diagnostic criteria of heart...

Sumario:BACKGROUND: N-terminal brain natriuretic peptide precursor (NT-proBNP) and brain natriuretic peptide (BNP) are mainly produced and secreted in the heart. In 2008, the European Heart Association recommended that serum BNP/NT-proBNP levels should be included in one of the diagnostic criteria of heart failure. Serum NT-proBNP is more stable than BNP, and the detection results are less affected by objective factors, so it is widely used. At present, NT-proBNP has long been beyond the scope of heart failure markers, and has a wide range of clinical value in the evaluation and prediction of some serious diseases. This study prospectively studied the predictive value of serum NT-proBNP in pediatric intensive care unit (PICU). METHODS: This was a prospective study involving 375 children in the PICU. The patients were divided into three groups: non-risk, low-risk, and high-risk groups. Serum NT-proBNP levels and the 28-day mortality rate were analyzed. RESULTS: The serum NT-proBNP levels and the mortality of the high-risk group was significantly higher than those of the low- and non-risk groups (P<0.01 in both cases). Receiver operating characteristic curve (ROC curve) analysis showed that the area under the curve was 0.705 (P<0.001, sensitivity =0.643, specificity =0.692). Death multivariate binary logistic regression analysis indicated that NT-proBNP was not an independent factor for 28-day mortality. CONCLUSIONS: Serum NT-proBNP was significantly correlated with the severity of illness for critically ill patients in PICU. Although high levels of NT-proBNP indicated greater severity, this was not an independent risk factor affecting the prognosis of patients.
