Free T4, free T3 and TSH before and 30 min after TRH administration have been evaluated in 35 elderly patients with atrial fibrillation (AF), in 35 elderly normal subjects (AN) and compared with results obtained in 36 young men (YN). No significant differences were evidenced between AF and AN, especially no mild hyperthyroidism was discovered in AF. In comparison with YN, there was no alteration of free T4 with age but free T3 is dramatically decreased; concerning TSH, there is a significant decrease before and after TRH in AN males whereas TSH levels in other subgroups are similar to those in YN.
对35例老年房颤（AF）患者、35例老年正常受试者（AN）以及36例青年男性（YN）在注射促甲状腺激素释放激素（TRH）前及注射后30分钟测定了游离甲状腺素（Free T4）、游离三碘甲状腺原氨酸（free T3）和促甲状腺激素（TSH）。AF组与AN组之间未发现显著差异，尤其是未在AF组中发现轻度甲状腺功能亢进。与YN组相比，Free T4未随年龄改变，但free T3显著降低；关于TSH，AN组男性在TRH注射前后显著降低，而其他亚组的TSH水平与YN组相似。
