The etiology of senile cardiomyopathy

老年人心肌病是由包括遗传因素在内的各种病因引起的非均质的心肌病变,包括原发性和继发性心肌病。心肌病在病因学上分为遗传性、获得性和混合性。加强对致病基因的筛查以及危险因素的控制,将极大地改善患者的预后。

Senile cardiomyopathy can be categorized as the primary- and secondary- types, and results in varied phenotypes including dilated, hypertrophic and restrictive patterns. The etiology- of cardiomyopathy may be genetic, ac- quired and mixed. Strengthening the screening of pathogenic genes and the control of risk factors will greatly improve the prognosis of patients.
