Does carvedilol improve serum h-FABP, BNP, and cardiac function in children with chronic heart failure?
Carvedilol significantly improves cardiac function and reduces serum biomarkers of heart failure (h-FABP and BNP) in children with chronic heart failure.
p-value: p=< 0.01
OBJECTIVE: To observe the changes of serum heart-type fatty acid-binding protein (h-FABP) and brain natriuretic peptide (BNP) in children with chronic heart failure (CHF) and evaluate the effects of carvedilol. METHODS: A total of 36 patients with CHF, including 17 of endocardial fibroelastosis and 19 of dilated cardiomyopathy, were enrolled and were randomly divided into a carvedilol treatment group (group A) and a conventional treatment group (group B). Group A (n = 16) was treated with carvedilol and conventional treatment and group B (n = 20) was managed with conventional treatment only. Thirty healthy children were enrolled as controls. The concentrations of serum h-FABP and BNP were measured by enzyme-linked immunosorbent assay, and the left ventricular end-systolic diameter, left ventricular end-diastolic diameter, left ventricular ejection fraction (LVEF), left ventricular fractional shortening (LVFS), and cardiac index (CI) were measured by echocardiography. RESULTS: The concentrations of serum h-FABP and BNP in patients with CHF were significantly higher than in the control group (21.7 ± 4.3 ng/mL vs. 6.3 ± 1.7 ng/mL, 582.4 ± 180.6 pg/mL vs.31.2 ± 9.8 pg/mL, all P 0.05). h-FABP concentration in patients with CHF was positively correlated with BNP (r = 0.78, P < 0.01) but negatively correlated with LVEF, LVFS, and CI (r = -0.65, -0.64, and -0.71, respectively; all P < 0.01). BNP concentration was also negatively correlated with LVEF, LVFS, and CI (r = -0.75, -0.61, and -0.79, respectively; all P<0.01). After treatment with carvedilol, the serum concentrations of h-FABP and BNP in group A were lower than in group B, and the magnitude of heart rate reduction, improvement of LVEF, LVFS, and CI, and reduction of left ventricular end-systolic diameter and left ventricular end-diastolic diameter in group A were all greater than in group B (all P < 0.01). Treatment with carvedilol had no adverse events. CONCLUSIONS: Serum concentrations of h-FABP and BNP can be used as biomarkers to evaluate the severity of heart failure, and carvedilol can significantly improve heart function in children with CHF.
Sun et al. (Fri,) conducted a rct in Chronic heart failure (n=66). Carvedilol vs. Conventional treatment was evaluated on Changes in serum h-FABP, BNP, and cardiac function parameters (p=< 0.01). In children with chronic heart failure, carvedilol significantly reduced serum h-FABP and BNP and improved cardiac function compared to conventional treatment alone (all P < 0.01).
