OBJECTIVES: To determine whether acute left ventricular dysfunction (LVD) causes significantly higher elevation of N-terminal pro-B-type natriuretic peptide (NT-proBNP) levels than comparable chronic LVD. STUDY DESIGN: Plasma levels of NT-proBNP were measured in 10 pediatric patients diagnosed with acute LVD, in 7 pediatric patients with stable chronic dilated cardiomyopathy (DCM) and comparable levels of echocardiographic dysfunction, and during 5 episodes of acute exacerbation in patients with heart failure. Levels were compared using Mann-Whitney and analysis of variance for rank tests. RESULTS: Plasma levels of NT-proBNP were excessively elevated in patients with acute LVD in the first 24 to 48 hours of hospitalization (median level, 65,600 pg/mL), and were significantly higher than those in patients with chronic DCM (median level, 1125 pg/mL; P < .0001). NT-proBNP levels decreased in the subsequent days in 83% of patients with serial measurements. The NT-proBNP levels were lower In 5 episodes of acute exacerbation than in acute LVD (median level, 7185 pg/mL; P < .003). CONCLUSIONS: Acute LVD is associated with elevated NT-proBNP level in children.
