本文分析了147例原发性扩张型心肌病临床资料,60岁以上老年组占40%,农民占74.8%,认为营养因素可能为本病基本病因或诱因。中度以上普大型心脏伴室内传导阻滞者应高度怀疑本病可能,超声心动图对诊断更有益。频发多源性室性早搏是本病猝死危险信号。心功能损害程度与预后有关,心电衰竭为本病死亡主要原因。
This article analyzes the clinical data of 147 cases of primary dilated cardiomyopathy, accounting for 40% of the elderly over 60 years of age, farmers accounted for 74.8%, that nutritional factors may be the underlying etiology or incentive. Moderate general large heart with intra-ventricular conduction block should be highly suspected of the disease may be, echocardiography more useful for the diagnosis. Frequent multi-ventricular premature beats is the risk of sudden death signal. The degree of cardiac dysfunction and prognosis, heart failure is the main cause of death.
