近年来发现,许多非甲状腺疾病患者甲状腺功能试验可出现异常,血清T_4、T_3水平降低,一些危重症患者的病情严重程度及病死率也与T_3、T_4水平有一定的相关性。慢性肺心病常伴有多脏器功能障碍。为了探索肺心病患者甲状腺功能状况,1986年5月至1987年4月我们对61例住院的肺心病患者血液中T_3、T_4、TSH的水平进行测定。61例肺心病患者中男性45例,女性16例;年龄30～82岁,平均59.5岁。所 In recent years, many abnormal thyroid function tests in patients with non-thyroid disease can be found. Serum levels of T_4 and T_3 are decreased. The severity and mortality of some critically ill patients are also related to T_3 and T_4 levels. Chronic pulmonary heart disease is often accompanied by multiple organ dysfunction. In order to explore the status of thyroid function in patients with cor pulmonale, from May 1986 to April 1987 we measured the levels of T 3, T 4 and TSH in 61 patients with cor pulmonale. Among the 61 patients with pulmonary heart disease, 45 were male and 16 were female, with a mean age of 59.5 years ranging from 30 to 82 years. The
