本文用放射免疫分析（ Ｒ Ｉ Ａ） 法检测了４１ 例急性心肌梗塞（ Ａ Ｍ Ｉ） 患者血清中的甲状腺激素（ Ｔ Ｔ３ ， Ｔ Ｔ４ ， Ｔ Ｓ Ｈ， Ｆ Ｔ３ ， Ｆ Ｔ４） 水平， 并与正常人及 Ａ Ｍ Ｉ患者的肌钙蛋白 Ｔ（ Ｔｎ Ｔ） 含量进行了比较。结果表明：４１ 例急性心肌梗塞患者的甲状腺激素中 Ｔ Ｔ３ 及 Ｆ Ｔ３ 水平分别为０ ．９４ ±０ ．４０ｎｇ／ｍ Ｌ 和１ ．０９ ±０ ．５７ｐｇ／ｍ Ｌ，与３７ 例正常对照组（ Ｔ Ｔ３ 为１ ．７３ ±０ ．３１ｎｇ／ ｍ Ｌ， Ｆ Ｔ３ 为３ ．１２ ±０ ．７５ｐｇ／ｍ Ｌ） 均有高度显著性差异（ Ｐ＜ ０ ．０１） 。动态观察甲状腺激素水平在 Ａ Ｍ Ｉ 患者溶栓治疗过程中的变化表明： Ｔ Ｔ３ 及 Ｆ Ｔ３ 水平随着 Ａ Ｍ Ｉ治疗的进行和病情的稳定慢慢增加及至正常， 与诊断 Ａ Ｍ Ｉ的“金标准” Ｔｎ Ｔ 呈高度负相关（ ｒ１ ＝ － ０ ．７９９８ ，ｒ２ ＝ － ０ ．７８５８） 。研究提示： 急性心肌梗塞患者血清甲状腺激素水平分析可用于 Ａ Ｍ Ｉ的辅助诊断。连续动态观察还可为 Ａ Ｍ Ｉ患者的疗效观察及预后判断提供切实的参考依据。
The levels of thyroid hormones (T T3, T T4, T S H, F T3, F T4) in serum of 41 patients with acute myocardial infarction (A M I) were measured by radioimmunoassay (RIA) Troponin T (Tn T) levels in normal subjects and A M I patients were compared. The results showed that the thyroid hormones in 41 patients with acute myocardial infarction were T 0 and T T3, respectively. 94 ± 0. 40 ng / m L and 1. 09 ± 0. 57pg / m L and 37 normal controls (1.73 ± 0.31ng / m T at T T3 and 3.12 ± 0.75 pg / m L at F T3) (P <0 .01). Dynamic observation of thyroid hormone levels in patients with A M I during thrombolytic therapy changes showed that: T T3 and F T3 levels with the A M I treatment and the stability of the disease slowly increased to normal, and the diagnosis of A M I “ Gold standard ”Tn T was highly negatively correlated (r1 = -0.7998, r2 = -0.7858). Study suggests that: serum thyroid hormone levels in patients with acute myocardial infarction can be used for the auxiliary diagnosis of A M I. Continuous dynamic observation can also provide a practical reference for the observation and prognosis of A M I patients.
