Predictors of Coronary Artery Aneurysms in Kawasaki Disease

Kawasaki disease (KD) is a common cause of cardiovascular morbidity in young children. No study has attempted to stratify risk factors for coronary artery involvement in Indian children. We attempted to study prospectively the risk factors for coronary involvement in children with KD in a tertiary care hospital between October 2009 and November 2011. The clinical details and investigations for all children admitted with KD were tabulated, and echocardiography was performed; 37 children were admitted with KD; and 8 children (21%) had coronary artery abnormalities. Prolonged fever, wider dispersion of symptoms, and pyuria were significantly associated with the development of coronary lesions. Clinical factors such as wider dispersion of symptoms and prolonged fever along with presence of pyuria can increase the risk of coronary lesions. The presence of these factors may help direct aggressive management and prevent loss of precious time.
