川崎病引起的心血管损害与冠状血管免疫性损伤,血管内皮功能障碍有密切关系,冠状动脉炎在川崎病急性期后持续存在,是导致血管内膜纤维性增生,血管腔狭窄的重要原因。超声心动图诊断川崎病并发心血管损害对判断病情、指导治疗和估测预后发挥越来越重要的作用,尤其对冠状动脉扩张和冠状动脉瘤形成的诊断具有特异性,能清晰的显示冠状动脉内径、扩张程度。超声心动图还能明确显示冠状动脉狭窄的特点,但对检出冠状动脉远端的损害有一定的困难。 Kawasaki disease caused by cardiovascular damage and coronary vascular immune damage, vascular endothelial dysfunction are closely related to coronary artery inflammation in Kawasaki disease persist after the acute phase, is leading to vascular intimal fibrosis, vascular stenosis of the important reasons. Echocardiography in the diagnosis of Kawasaki disease complicated with cardiovascular damage plays an increasingly important role in judging the condition, guiding the treatment and estimating the prognosis, especially for the diagnosis of coronary artery dilatation and coronary aneurysm. It can clearly show the coronary artery Inside diameter, degree of expansion. Echocardiography can also clearly show the characteristics of coronary stenosis, but the detection of distal damage to the coronary arteries have some difficulties.
