Study of NT-proBNP and Hs-Troponin I biomarkers for early detection of children's heart function of protein-energy malnutrition

The Protein Energy Malnutrition (PEM) is the condition of a lack of carbohydrate and protein stores in the body that trigger chronic failure nutrient intake and body maintenance function caused to impact the heart functions. The NT-pro-BNP and Hs-Troponin I proteins were found as the indicator of cardiac dysfunction. The sixty subjects of PEM, analyzed by standard of Indonesia Healt Ministry as well as nutritional status. The blood electrolytes examined by laboratory assay and the levels of Hs-Troponin 1 and NT-Pro-BNP were analyzed by Immune-Chromatography method. Assessing of the ventricular mass with the seeing the peak of the diastolic flow rate of left ventricular that estimated by the curve of the receiver operating characteristic and the area under the curve (P<0.05). The result has shown that the PEM decreased in the left ventricular mass for impaired heart function and systolic disorder. The Hs-Troponin I (90.9%) has better sensitivity than NT-pro-BNP (85.5%) if the merger of those markers possesses the lowest sensitivity (81.8%). These proteins have good bio-markers in heart function, mainly in cases where PEM is present.
