川崎病是一种病因尚不明确的以全身血管炎为主要病变的急性、自限性儿童发热出疹性疾病。未经治疗患儿有20%～25%发生冠状动脉损害,晚期可发展成冠状动脉狭窄或血栓形成,甚至导致心肌梗死。因此,早期诊断川崎病患儿冠状动脉病变、心肌运动异常、心脏收缩舒张功能受损等是十分必要的。近年来,Tei指数、多普勒组织成像、应变率成像等技术越来越能准确地评价川崎病患儿心功能损害情况。 Kawasaki disease is a cause of etiology is not yet clear to systemic vasculitis as the main lesion of acute, self-limiting children fever rash disease. In untreated children, 20% to 25% of children develop coronary artery lesions, advanced coronary artery stenosis or thrombosis, and even myocardial infarction. Therefore, early diagnosis of Kawasaki disease in children with coronary artery disease, myocardial dysfunction, cardiac systolic and diastolic dysfunction is very necessary. In recent years, Tei index, Doppler tissue imaging, strain rate imaging technology more and more accurate assessment of children with Kawasaki heart damage.
