根据世界卫生组织研究组的定义,心肌病系指:“以心肌障碍导致心力衰竭为主要表现的各种原因不明的心脏疾病。”这一定义强调了进一步探索病因的必要性。尽管其病因、病程和自然史至今仍未阐明,但临床上曾有几种不同的心肌病分类法。最常用的功能性分类法系Goodwin分类法,把心肌病分为充血性、肥厚性和限制性3大类。此分类法的优点在于尽管病因不明,但却能对此3型的病理、功能和临床表现进行鉴别。
According to the World Health Organization study group, cardiomyopathy means “a variety of unknown causes of heart disease characterized by heart failure leading to heart failure.” This definition underscores the need to further explore the cause. Although its etiology, course of disease and natural history have not yet been elucidated, but there are several clinical cardiomyopathy classification. The most commonly used functional taxonomy is the Goodwin classification, which classifies cardiomyopathy into three categories: congestive, hypertrophic and restrictive. The advantage of this taxonomy is that the pathology, function, and clinical presentation of this type 3 can be identified despite the unknown etiology.
