目的 :了解老年心功能不全病人的甲状腺激素水平的变化规律。方法 :用放射免疫分析检测 1 30例心功能不全的老年病人和 4 0例心功能正常的老年健康志愿者血清甲状腺激素水平。结果 :心功能Ⅰ级和Ⅱ级病人其TT3 值和FT3 值的下降与正常的对照组相比 ,有显著差异 (p <0 0 1 ) ,而TT4及FT4无差异 ;Ⅲ和Ⅳ级心功能的病人其FT4的下降有差异 (p <0 0 5 ) ,TT3 和FT3 的下降有显著差异 (p <0 0 1 ) ,而TT4无差异。结论 :临床上对老年心功能不全的病人检测其甲状腺激素水平的变化 ,有一定的反映病情状况及观察预后的作用 ,亦可了解老年心功能不全病人内分泌代谢的变化 ,同时在分析甲状腺功能时 ,应了解病人心功能情况
Objective: To understand the changes of thyroid hormone levels in elderly patients with heart failure. Methods: Thirteen elderly patients with heart failure and 40 healthy volunteers with normal heart function were tested for serum thyroid hormone by radioimmunoassay. Results: The TT3 and FT3 decreased in patients with grade I and II of cardiac function were significantly lower than those in normal controls (p <0.01), but not in patients with TT4 and FT4. Grade III and IV cardiac function (P <0 05). There was a significant difference in the reduction of TT3 and FT3 (p 0 01) but no difference in TT4. Conclusions: The changes of thyroid hormone levels in elderly patients with cardiac dysfunction, which may reflect the condition and prognosis, may also be related to the changes of endocrine and endometrial metabolism in elderly patients with cardiac dysfunction. At the same time, in the analysis of thyroid function , Should understand the patient’s cardiac function
