Risk factors for Kawasaki disease-associated coronary abnormalities differ depending on age.

Introduction: The clinical manifestations and risk factors for developing coronary artery abnormalities (CAA) in Kawasaki disease (KD) might differ depending on age.

Materials And Methods: From January 2001 to July 2007, 161 patients with an age younger than 1 year (younger group) and 60 patients with an age older than 5 years (older group) were diagnosed with KD at the Korea University Medical Center. Their medical records were reviewed retrospectively and the two groups were compared in terms of a number of variables commonly associated with the development of CAA, including clinical manifestations and laboratory findings.

Incomplete Kawasaki disease in patients younger than 1 year of age: a possible inherent risk factor.

Kawasaki disease (KD) patients younger than 1 year of age are at especially high risk of developing coronary artery abnormalities (CAA). To define the clinical characteristics of this group, as well as the risk factors predisposing them to CAA, we reviewed the medical records of 136 KD patients younger than 1 year of age who were treated at the Korea University Medical Center from January 2001 to July 2006. Of these patients, 16 developed CAA (11.
