目的 探讨急性心肌梗死患者甲状腺功能检测的临床意义。方法 回顾性分析72 例急性心肌梗死(AMI)患者的血清甲状腺激素水平，以30例健康的退休职工为对照组。结果 急性心肌梗死组有4例合并有甲状腺疾病，34例出现正常甲状腺功能病态综合征，急性心肌梗死组（68例）与对照组相比血清总三碘甲状腺原氨酸(TT3)下降,差异有统计学意义 (P<0.001），总甲状腺素（TT4)，游离三碘甲状腺原氨酸(FT3)下降也有显著性差异（P <0.01），游离甲状腺素 (FT4 )，促甲状腺素（TSH）与对照组比较差异无统计学意义（P >0.05）。结论 对于急性心肌梗死患者，应该常规检测甲状腺功能，以便更好的进行治疗和预后判断。

Objective To investigate the clinical value of thyroid function tests in patients with acute myocardial infarction. Methods A retrospective analysis of serum thyroid hormone levels in 72 cases of acute myocardial infarction (AMI) patients and 30 healthy controls of retired workers were carried out. Results In the acute myocardial infarction group, 4 patients were associated with thyroid disease, 34 cases appeared to have euthyroid sick syndrome. As compared with the control group, 68 cases of patients in the acute myocardial infarction group had declined in serum TT3 with significant difference (P<0.001), and the levels of TT4 and FT3 were also declined with significantly difference (P <0.01). There was no significant difference with respect to the serum levels of FT4 and TSH (P> 0.05). Conclusion The thyroid function in patients with acute myocardial infarction should be routine detected in order to have a better treatment and prognosis.
