Whether apical hypertrophic cardiomyopathy is a variant of classic hypertrophic cardiomyopathy or a separate entity is controversial. This is a case report of an apical hypertrophic cardiomyopathy. The patient was a 67-year-old man associated with giant negative T waves in electrocardiogram and asymmetric apical hypertrophy on echocardiogram. He died of liver cirrhosis and liver cell carcinoma. At necropsy the heart showed apical hypertrophy grossly and extensive disarray of myocardial fibers near the apex of the left ventricle histologically. The necropsy findings were indistinguishable from those of classic hypertrophic cardiomyopathy. This suggests that apical hypertrophic cardiomyopathy is a variant of hypertrophic cardiomyopathy.
心尖肥厚型心肌病是经典肥厚型心肌病的一种变异型还是一个独立的疾病实体存在争议。本文报告一例心尖肥厚型心肌病病例。患者为一名67岁男性，心电图显示巨大倒置T波，超声心动图显示心尖不对称肥厚。他死于肝硬化和肝细胞癌。尸检时心脏肉眼可见心尖肥厚，组织学检查显示左心室心尖附近心肌纤维广泛紊乱。尸检结果与经典肥厚型心肌病难以区分。这表明心尖肥厚型心肌病是肥厚型心肌病的一种变异型。
