本文分析了61例肺心病呼吸衰竭患者的甲状腺激素水平,其T_4、T_3均值低于正常成人组。单纯呼衰组T_4、T_3均值低于正常组。单纯呼衰组、呼衰伴心衰组、呼衰伴肺脑组T_4、T_3均值依次下降,表明随着肺心病病情加剧,甲状腺激素水平也相应地下降;并且甲状腺激素水平对疾病的预后有一定的意义。血清T_4、T_3减少,TSH无明显变化,提示非甲状腺原发病变所致,可能与代偿性游离甲状腺素水平增高有关。
Thyroid hormone levels in 61 patients with CPHD were analyzed in this paper. The mean levels of T_4 and T_3 were lower than those in normal adults. The simple mean respiratory failure group T_4, T_3 average lower than the normal group. Patients with simple respiratory failure, respiratory failure with heart failure, respiratory failure with pulmonary brain T_4, T_3 mean decreased in turn, indicating that with the aggravating of pulmonary heart disease, thyroid hormone levels also decreased accordingly; and thyroid hormone levels on the prognosis of disease A certain meaning. Serum T_4, T_3 decreased, TSH no significant change, suggesting that non-thyroid induced lesions may be compensatory increase in the level of free thyroxine.
