1.How long do I need to be hospitalized for Kawasaki disease? To what condition can I be discharged? Generally, patients with Kawasaki disease can be discharged after 10 to 14 days of hospitalization, when their body temperature drops to normal, symptoms disappear, and indicators such as blood count, CRP and liver function are basically normal. In case of combined coronary aneurysm, the dosage of antithrombotic drugs should be adjusted and then discharged. 2.Do I need to continue to take medication after discharge? What are the principles of medication? To what standard can the medication be stopped? If there is no coronary artery damage, you should keep taking oral aspirin (ASP) after discharge from the hospital, and generally stop taking it in 3 months. If there is coronary artery damage, ASP should be taken until the coronary artery returns to normal. For those with coronary artery damage leading to coronary aneurysm, antithrombotic drugs and drugs to prevent myocardial remodeling should be added. 3.What are the principles of follow-up review (are there different follow-up plans according to the degree of coronary artery damage)? What tests should be done for the review? Kawasaki disease requires long-term follow-up, mainly to see if there is any involvement of coronary arteries. It is usually best to follow up once a year, 1, 2, 3, 6, 12 months after discharge. Routine follow-ups include blood work, electrocardiogram and echocardiogram. In case of combined coronary aneurysm, coronary angiography with dual-source CT is required in the acute stage, and after 3 months, transcatheter coronary angiography is required to examine the severity of coronary lesions in detail and to determine the treatment plan. The specific plan is as follows: Graded management plan for Kawasaki disease combined with coronary artery damage Kawasaki disease follow-up: 1, 2, 3, 6, 12 months and 1 follow-up visit per year. Grade I: No coronary aneurysm (after 2 weeks) Oral ASP for 3 months, no need to restrict activities. Grade II: transient coronary artery dilatation that subsides at 1 month. Management is the same as grade Ⅰ. Grade III: Mildly dilated coronary artery with an internal diameter of less than 4 mm, still dilated at 1 month. ASP is used until 3 months after the coronary arteries return to normal. Appropriate activity restriction. Grade IV: moderate size coronary artery aneurysm with an internal diameter between 4 and 8 mm. Antithrombotic therapy, no strenuous activity. Grade V: Huge coronary aneurysm with an internal diameter greater than 8mm. Antithrombotic treatment, prohibition of any activity, coronary angiography if necessary. Grade VI: Coronary artery stenosis and myocardial ischemia. Clinical symptoms with angina pectoris, ECG showing ischemic changes, ultrasound showing thrombosis and segmental motion abnormalities. Coronary angiography should be performed when possible to clarify the site and extent of disease. Management is the same as class V. 4.How do children with Kawasaki disease get vaccinated? Vaccination is generally required after 11 months and then on time after one year of simple memory. 5.Does Kawasaki disease recur? There will be recurrence. The recurrence rate is 2%-3% and sibling morbidity 1%-2%. Infection is a common precipitating factor for Kawasaki disease. Active prevention and control of infection at any site can effectively prevent recurrence. 6.Can children exercise freely in their daily activities? Is there anything else that needs special attention? Kawasaki disease children without coronary artery damage can move freely; if they have mild coronary artery damage, they should avoid strenuous activities; if they have moderate to severe coronary artery damage, especially if they are taking antithrombotic drugs, any activities are prohibited. 7. Do children with Kawasaki disease have a higher risk of developing cardiovascular disease as adults? Children who have had Kawasaki disease have an increased risk of cardiovascular disease in adulthood.
