川崎病的心血管后遗症造成小儿突然死亡和严重心脏损害。对此应全面监护。一、冠状动脉瘤、扩大性病变急性期约半数引起冠状动脉的扩大性病变,残存冠状动脉瘤者占10～20%,经1～2年半数正常,动脉瘤消退。其余残留冠状动脉瘤或冠状动脉壁不整,甚而致闭塞性病变。发展为缺血性心脏病者占3%以下。急性期冠状动脉癌发展成闭塞性病变的危险因素:(1)巨大冠状动 Kawasaki disease caused by cardiovascular sequelae sudden death and severe heart damage. This should be fully guardianship. First, coronary aneurysms, enlarged lesions of about half of the acute cause of coronary enlargement lesions, residual coronary aneurysms accounted for 10 to 20%, after 1 to 2 years and a half normal, aneurysm subsided. The remaining residual coronary aneurysm or coronary artery wall is not the whole, and even cause occlusive disease. The development of ischemic heart disease accounted for less than 3%. Acute coronary artery cancer into occlusive disease risk factors: (1) huge coronary artery
