摘    要:目的探讨老年慢性心力衰竭患者甲状腺激素的变化及其临床意义。方法收集老年慢性心力衰竭76例,其中心功能Ⅱ级25例,Ⅲ级28例,Ⅳ级23例,并选择30例非心力衰竭老年体检者作为对照组,以放射免疫法检测血浆总三碘甲状腺氨酸(L)、总甲状腺素(T4)、游离三碘甲状腺氨酸(FT3)、游离甲状腺素(FT4)、促甲状腺素(TSH)。结果心功能Ⅱ级组T3(1.28±0.51)nmol/L]和FT3(3.01±0.78)pmol/L]与对照组分别为(2.34±0.52)nmol/L和(4.27±0.64)pmol/L]比较,明显降低(均P〈0.05),且随着心功能分级增加,心功能Ⅲ级、Ⅳ级T3和FT3水平则进一步降低(P〈0.叭),心功能Ⅲ级T3和FT3分别为(0.87±0.43)nmol/L和(2.42±0.61)pmol/L,心功能Ⅳ级T1和FT1分别为(0.60±0.36)nmol/L和(2.09±0.71)pmol/L。结论T3和FT3作为重要的内分泌激素,参与心力衰竭的病理生理进程,可作为老年慢性心力衰竭患者早期临床诊断标志物。

Abstract:Objective To investigate the changes and clinical significance of thyroid hormones function in elderly patients with chronic heart failure.Methods A total of 76 elderly patients with chronic heart failure were divided into different groups according to NYHA categorization:NYHAⅡgroup (25 patients), NYHAⅢgroup (28 patients) and NYHA IV group (23 patients).Thirty non-heart failure elderly subjects served as control group.T3 , T4 , FT4 , FT3 , TSH were tested by radioimmunoassay.Results Compared with T3 and FT3 levels (2.34 ±0.52)nmol/L and (4.27 ±0.64) pmol/L respectively] in control group, T3 and FT3 levels(1.28±0.51) nmol/L and (3.01 ±0.78) pmol/L respectively] in NYHAⅡgroup were decreased (P〈0.05);and with the deterioration of cardiac function functional class Ⅲ-Ⅳ (P〈0.01), patients showed T3 and FT3 levels (0.87 ±0.43) nmol/L and (2.42 ± 0.61) pmol/L respectively] in NYHAⅢgroup, and (0.60 ±0.36) nmol/L and (2.09 ±0.71) pmol/L respectively ] in NYHA IV group.Conclusions T3 and FT3 play an important role in chronic heart failure, can serve as the early predictors in elderly patients with chronic heart failure.
Keywords:elderly patients  chronic heart failure  thyroid hormones  clinical significance
