25 patients affected by Primary Hypothyroidism and a control group of 25 subjects were studied with M-mode and Two-dimensional echocardiography. In hypothyroid patients mean left ventricular and aortic root dimensions were normal compared to control subjects. Pericardial effusion was found in 22 out of 25 patients (88%). Septal hypertrophy was found in 12 hypothyroid patients (48%), only in 3 out of these 12 patients left ventricular posterior wall hypertrophy was found. A moderate left atrial enlargement was found in 7 out of 25 hypothyroid patients. Two-dimensional echocardiography revealed an uniform degree of parietal hypertrophy from the basal segments to the cardiac apex. Therefore the main echocardiographic findings in hypothyroidism are: presence of pericardial effusion and asymmetrical septal hypertrophy. No correlations between these echocardiographic findings and age of patients, severity of "biochemical" alterations and duration of the thyroid disease was observed.
对25例原发性甲状腺功能减退患者和25名对照受试者进行了M型和二维超声心动图研究。与对照受试者相比，甲状腺功能减退患者的左心室和主动脉根部平均尺寸正常。25例患者中有22例（88%）发现心包积液。12例甲状腺功能减退患者（48%）发现室间隔肥厚，其中仅12例中的3例发现左心室后壁肥厚。25例甲状腺功能减退患者中有7例发现中度左心房扩大。二维超声心动图显示从心底段到心尖存在均匀程度的心肌肥厚。因此，甲状腺功能减退的主要超声心动图表现为：心包积液和不对称性室间隔肥厚。未观察到这些超声心动图表现与患者年龄、“生化”改变严重程度及甲状腺疾病病程之间的相关性。
