Children with Kawasaki disease had significantly reduced peak oxygen consumption and ventilatory threshold years after diagnosis, linked to persistent coronary aneurysms.
Does a history of Kawasaki disease impair long-term aerobic capacity and oxygen consumption in children and adolescents?
Children with a history of Kawasaki disease exhibit impaired long-term aerobic capacity, particularly those with persistent coronary aneurysms.

UNLABELLED: Kawasaki disease (KD) is a systemic inflammatory condition, likely triggered by a respiratory infection, inducing myocardial inflammation, and complicated with coronary aneurysms. The objectives are to measure the late cardiopulmonary exercise response and associate the severity of the acute episode with the long-term aerobic capacity. Data on the acute KD episode were collected retrospectively. Children and adolescents with past KD underwent standardized ergometer cardiopulmonary exercise testing. Regression analysis was used to associate coronary Z-scores and acute biomarkers, including maximum N-terminal pro-B-type natriuretic peptide (NT-proBNP), with the exercise parameters. Of 43 patients diagnosed with KD (mean age 4.97 ± 2.88 years, 42% females), 30 were age-and-sex matched after a mean of 6.78 ± 3.00 years (range 1.5-16 years) with 15 controls. Peak oxygen consumption (peakVO CONCLUSION: Children with KD had reduced aerobic capacity 7 years after the diagnosis. Maximum acute NT-proBNP and acute coronary Z-score were not associated with the late impaired exercise capacity, but persistent coronary aneurysms were. WHAT IS KNOWN: • Acute coronary Z-score and blood NT-proBNP are markers of disease severity in Kawasaki disease. • Kawasaki disease is associated with late coronary ischaemic complications. WHAT IS NEW: • In Kawasaki disease patients, several years after the diagnosis, peak exercise mass-related oxygen consumption and ventilatory threshold are decreased, and body mass index is increased. • Persistent coronary aneurysms, but neither acute coronary Z-score nor acute maximum NT-proBNP, are associated with the late impaired exercise capacity.
