ABSTRACT
BACKGROUND:
This study aimed to determine whether ongoing vascular inflammation presents in patients who had coronary artery aneurysms (CAAs) caused by Kawasaki disease (KD).METHODS:
Subjects were 26 patients with a history of KD; 15 had giant CAA (gCAA) ≥ 8.0 mm and 11 had smaller CAA (smCAA) < 8 mm in the acute phase. They underwent X-ray computed tomography and 18F-fluorodeoxyglucose positron emission tomography. We determined the maximum coronary target-to-background ratio (CaTBR) and the mean thoracic aorta TBR (TaTBR) in each patient. They were compared between groups, and their correlation with various variables was determined.RESULTS:
CaTBR and TaTBR were significantly higher in gCAA than in smCAA (P < .005 for both values) and were significantly higher even in patients without any metabolic risk factor (P < .05 for both values). The CAA size in acute phase significantly positively correlated with CaTBR (R2 = 0.32) as well as TaTBR (R2 = 0.28). Also, TaTBR significantly positively correlated with CaTBR (R2 = 0.32) as well as cumulative number of metabolic risk factors (trend, P = .03).CONCLUSIONS:
Ongoing vascular inflammation may present long after KD, especially in patients with severe inflammation expressed as gCAA in the acute phase.Palavras-chave
