应用放射免疫法测定68例心脏病充血性心力衰竭(CHF)病人,30例心功能代偿期心脏病病人及47例健康人血清T_4、T_3及rT_3水平,结果为CHF病人的血清T_3水平显著低于后二者、而rT_3水平显著高于后二者(P<0.01),且血清T_4、T_3及rT_3水平与CHF病人预后密切相关。可见应用血清T_4、T_3及rT_3水平变化预测CHF病人预后,不仅方法简单,而且较为敏感。
Serum levels of T_4, T_3 and rT_3 in 68 patients with congestive heart failure (CHF), 30 patients with decompensated cardiac disease and 47 healthy controls were measured by radioimmunoassay. The results showed that serum T_3 level was significantly higher in CHF patients Lower than the latter two, while the level of rT_3 was significantly higher than the latter two (P <0.01). The serum levels of T_4, T_3 and rT_3 were closely related to the prognosis of CHF patients. It can be seen that the application of serum T 4, T 3 and rT 3 levels to predict the prognosis of patients with CHF is not only simple but also sensitive.
