RESUMO
We conducted this study to compare the incidence of coronary artery dilatation in children with Incomplete and Classical Kawasaki disease, diagnosed as per AHA criteria. Subjects were included on a retrospective review of records (2002-2007); those with a discharge diagnosis of Kawasaki disease were enrolled. A total of 29 patients were identified (3.1 per 1000 pediatric admissions), out of which 22 were boys (median age: 4.8 years; range: 4 months-11 years). Seventeen (58.6%) had Classical KD and twelve (41.4%) children had Incomplete KD. All children received IVIG and underwent echocardiography. Coronary involvement was more in Incomplete KD (11/12 = 91.6 %) as compared to Classical KD (7/17= 41.1%). The sensitivity, specificity and predictive value of AHA criteria to detect coronary artery dilatation was 39%, 9%, and 41%, respectively. We conclude that children presenting with Incomplete Kawasaki disease are at a higher risk of coronary artery abnormalities.
