近年来,对心肌肥大的形态学诊断有了新进展。本文复习心肌活检、超声心动图、心血管造影和心电图的形态诊断资料,以提高对心肌肥大的诊断水平。一、心肌肥大的活组织检查 Schaper对主动脉瓣缺损的左室肥厚进行活检,发现轻度肥大的心肌细胞除了肌节排列不规则和线粒体异常外,其它结构正常。重度肥大的左心室肌的重量增加三倍,线粒体和肌原纤维增加二倍,细胞浆增加五倍,非肌细胞与肌细胞的比例为1:4(正常为1:9)。
In recent years, morphological diagnosis of myocardial hypertrophy has made new progress. This review of myocardial biopsy, echocardiography, cardiovascular angiography and ECG morphological diagnostic data to improve the diagnosis of myocardial hypertrophy. First, cardiac hypertrophy biopsy Schaper on aortic valve defect left ventricular hypertrophy biopsy and found that mild hypertrophic cardiomyocytes in addition to the irregular arrangement of mitotic and mitochondrial abnormalities, the other structure is normal. Severe hypertrophy of the left ventricular muscle increased threefold, doubling of mitochondria and myofibrils, and a fivefold increase in cytoplasm, with a ratio of non-myocyte to muscle cells of 1: 4 (normal 1: 9).
