心脏淀粉样变性的特征是由于心室壁和室间隔淀粉样蛋白的细胞外沉着,导致舒张功能的损害。本文应用超声多普勒分析心脏淀粉样变性病人左室和肺静脉流入血液的速率来研究其左室舒张功能。材料和结果 64例病员均经组织活检证实为淀粉样变性,其中6例经心内膜活检证实。男43例,女21例,平均年龄60±11岁.每例病员均用脉冲和连续多普勒测定,并用热敏电阻鼻导呼吸仪同步记录呼吸时相。于 Cardiac amyloidosis is characterized by extracellular deposition of amyloid in the ventricular wall and septal space, resulting in impairment of diastolic function. In this paper, the left ventricular diastolic function of left ventricle and pulmonary vein in patients with cardiac amyloidosis was analyzed by Doppler echocardiography. Materials and Results Sixty-four patients were confirmed by histological biopsy as amyloidosis, of which 6 were confirmed by endocardial biopsy. There were 43 males and 21 females, with an average age of 60 ± 11 years. Pulse and continuous Doppler measurements were performed on each patient. Respiratory phases were simultaneously recorded using a thermistor nasal breathing apparatus. in
