Purpose: The purpose of this study is to evaluate the role of plasma brain natriuretic peptide(BNP) concentraion in Kawasaki disease(KD) and to evaluate the relationship of BNP and Tissue doppler imaging(TDI) in ventricular function
Methods: Plasma BNP concentration was obtained in the acute phases of KD(n=49) and non-KD(n=36). TDI and conventional echocardiography were performed in 49 patients in acute phase of KD. E’ velocity, A’ velocity at the lateral mitral annulus, interventricular septum, lateral tricuspid annulus were measured.
Results: The mean plasma BNP concentration in patients with KD in the acute phase was significantly higher than non-KD(61.1±100.9 pg/mL vs 13.2±9.5 pg/mL, P< 0.05). There was significant negative correlation with BNP and E’ velocity, E/E’ ratio at lateral mitral annulus in the aucte phase of KD.
Conclusion: The level of plasma BNP significantly increased in aucte phase of KD. But, there was no definite level of plasma BNP to diagnosis of KD. Diatolic ventricular function was decreased in acute phase of KD which BNP is elevated by TDI.
