Objective. To investigate the association between the aspartate aminotransferase (AST)/alanine aminotransferase (ALT) ratio\n(AST/ALT ratio, AAR) and intravenous immunoglobulin (IVIG) resistance, coronary artery lesions (CAL), and coronary artery\naneurysms (CAA) in children with Kawasaki disease (KD). Design. We retrospectively studied 2678 children with KD and divided\nthem into two groups: a low-AAR group and a high-AAR group with a median AAR of 1.13 as the cut-off point. The differences in\nlaboratory data, clinical manifestations, and coronary artery damage rates were compared between the two groups. Results. The\nincidence of CAL was higher in the low-AAR group than in the high-AAR group at 2 and 3-4 weeks after illness onset......................
