Objective:To investigate the incidence rate of carditis secondary to Kawasaki disease(KD)and its prognosis.Methods:Clinical data including serum myocardial enzymes such as CK-MB and cTnI

Holter and 12-lead and high frequency electrocardiograms and echocardiography test results

clinical manifestation

therapeutic methods and prognosis were analyzed retrospectively in 182 patients with KD.Results:About 35%patients had abnormal CK-MB

cTnI

ECG or UCG in acute phase

but they had no typical carditis clinical manifestation besides 2 cases with heart failure.90.66% cases were given intravenous immune globulin(IVIG)within ten days from the onset and within one to nine months of follow-up

CK-MB

cTnI

ECG or UCG had improved or returned to normal.Valvular inadequacy

hypokinetic left ventricle

ventricle amplification and pericardial effusion disappeared gradually in three to ten weeks

.Valvular lesion

heart amplification

constrictive pericarditis and serious arrhythmia were not found.Conclusion:This study showea about 35% patients with KD might develop low-grade transient myocarditis

pericarditis or endocarditis.An early diagnosis and therapy could lead for the patients to have good course and no sequelae.
