美国心肺和血液研究院于1991年6月13、14日就特发性扩张型心肌病(IDC)流行病学及病因学召集了一次学术研讨会,旨在(1)总结关于IDC患病率、流行病学、病因学、发病机理和治疗方面的资料;(2)系统阐述区分IDC与人群中亚临床心肌损害的标准;(3)确立有关IDC病因学、预防和治疗学方面的优先研究内容。 IDC以心脏扩大和心肌收缩功能失调为特征,须排除其它原因后方能作出诊断,超声心动图和核素心脏扫描在IDC诊断中有重要作用。IDC预后很差,病理初期主要用药物控制心衰,一旦心衰不能用药物控制时, The American Heart Lung and Blood Institute convened a symposium on the Epidemiology and Etiology of Idiopathic Dilated Cardiomyopathy (IDC) on June 13, 1991, to (1) summarize the prevalence of IDC , Epidemiology, etiology, pathogenesis and treatment; (2) systematically elaborate criteria for distinguishing between subclinical myocardial damage in IDC and populations; and (3) establish priority studies on etiological, preventive and therapeutic aspects of IDC content. IDC is characterized by cardiac enlargement and myocardial systolic dysfunction, which can be diagnosed only after excluding other causes. Echocardiography and radionuclide cardiac scanning play an important role in IDC diagnosis. IDC prognosis is poor, the initial pathology mainly used to control heart failure drugs, heart failure can not be controlled by drugs,
