为探讨慢性肺心病急性加重期患者甲状腺功能的变化,作者测定了37例肺心病患者血T_3、T_4水平。结果表明:肺心病患者血清中甲状腺素T_3、T_4含量明显低于健康对照组(p<0.01),而BMR明显高于五常人。对上述改变的原因进行了讨论,认为肺心病患者甲状腺功能不同程度的减退是机体对缺氧的一种保护性代谢反应。BMR增高是心肺功能不全所致。与甲状腺功能无明显相关。 In order to explore the changes of thyroid function in patients with chronic cor pulmonale during acute exacerbation, the authors measured the blood T_3 and T_4 levels in 37 patients with pulmonary heart disease. The results showed that the levels of thyroxine T_3 and T_4 in patients with cor pulmonale were significantly lower than those in healthy controls (p <0.01), while BMR was significantly higher than those in five normal controls. The reasons for the above changes were discussed, that patients with cor pulmonale at different levels of hypothyroidism is the body’s hypoxia as a protective metabolic reaction. BMR increased heart and lung dysfunction caused. No significant correlation with thyroid function.
