Patients diagnosed with Kawasaki disease are hospitalized to initiate treatment. Following discharge, it is crucial for these patients to be regularly followed up by a pediatric cardiologist. The initial follow-up examination should be conducted within 2 weeks, followed by checks between 6-8 weeks. Subsequently, follow-up intervals can be adjusted based on the condition of the coronary arteries. In the long term, it is particularly important to instill heart-healthy lifestyle habits in these children.
