Risk of coronary artery lesions in young infants with Kawasaki disease: need for a new diagnostic method

Abstract

Kawasaki disease infants younger than 3 months of age appear to be at higher risk for incomplete KD and early-onset CAL prior to the appearance of coronary artery sequelae. We suggest performing an echocardiogram and evaluating NT-proBNP in young infants with fever that has lasted longer than 2 days, regardless of the presence or absence of manifestations associated with KD.
