- Abstract
The N-terminal proBNP (NT-proBNP), produced by cardiomyocytes, has several reported utilities and associations in acute Kawasaki disease (KD). The objective of this study is to examine the relationship between serum values of NT-proBNP at time of KD diagnosis with cardiac systolic, diastolic function and electrocardiographic changes, at onset of the disease and during the first year of follow-up. KD was diagnosed in 127 children between March 2007 and July 2014, mean diagnostic age 3.5 ± 2.9 years. Coronary artery maximum z score was 2.6 ± 2.8 (range − 0.6 to + 18.9), with giant aneurysm in 5/122 (4.1%). Age-adjusted NT-proBNP was 2.6 ± 1.6 z score, 78/122 (63.9%) > 2.0. There was a crescendo correlation between onset NT-proBNP z score and C-Reactive protein (CRP) serum levels (slope + 0.49, p < 0.001). There was a crescendo correlation between NT-proBNP z score and indexed left ventricular (LV) mass (slope + 1.86, p = 0.02), LV diastolic function parameter E/e′ ratio (slope + 0.31, p = 0.04) and a decrescendo correlation with age-adjusted LV shortening fraction (SF) (− 0.63, p = 0.02). Lower SF z score, higher left ventricular mass index and E/e′ ratio were associated with higher NT-proBNP z score, but without correlation with CRP levels. Within 2–3 months from the onset of the disease, there was a resolution of the systolic dysfunction. Electrocardiographic parameter changes were associated with decreased LV shortening fraction but not with NT-proBNP. KD patients with elevated NT-proBNP at onset have sub-clinical myocardial involvement and might benefit from follow-up and continued evaluation, even in the absence of coronary artery involvement.
