典型充血性心肌病的心室腔明显扩大,有报道称心室腔越大预后越差,然而心肌纤维保存越好预后越佳。心脏轻度扩大的充血性心肌病(MDCM)被规定为终末期心力衰竭,并符合下列条件:(1)特发性心肌病伴严重心力衰竭(心功能 NYHAIV 级);(2)左室喷血分数(LVEF)<30％;(3)左室无或仅有轻度扩大,即扩大程度小于按体表面积校正的正常值的15％。20例初步诊断为 MDCM,其中8例(移植组)接受心脏移植。移植组中4例死亡,另
Typical congestive cardiomyopathy ventricular cavity was significantly enlarged, it has been reported that the greater the ventricular cavity the prognosis worse, but the better the preservation of myocardial fibers the better the prognosis. Myocardial mildly enlarged congestive cardiomyopathy (MDCM) is defined as end-stage heart failure and meets the following criteria: (1) idiopathic cardiomyopathy with severe heart failure (NYHAIV class of cardiac function); (2) left ventricular spray (LVEF) <30%; (3) No or only mild enlargement of the left ventricle, ie less than 15% of normal corrected for body surface area. Twenty patients were initially diagnosed as MDCM, and 8 patients (transplantation group) underwent heart transplantation. Four patients died in the transplant group
