This current cross-sectional study investigates the relationship between thyroid hormones and peripheral artery disease (PAD) among euthyroid Chinese population aged 40 years and above. Serum free triiodothyronine (FT3), free thyroxin (FT4), thyroid-stimulating hormone (TSH), and thyroid antibodies were measured. PAD was defined as ankle-brachial index (ABI) < 0.9. There were 91 (2.9%) PAD cases among the 3,148 euthyroid study participants. Participants in the highest quartile of FT3 and free-triiodothyronine-to-free-thyroxin (FT3/FT4 ratio) had a decreased risk of prevalent PAD (multivariate-adjusted odds ratio, 95% confidence interval: 0.32, 0.15-0.62, P for trend = 0.01 and 0.31, 0.13-0.66, P for trend = 0.004, respectively) compared to those in the lowest quartile. To conclude, FT3 levels and the FT3/FT4 ratio was inversely associated with prevalent PAD in euthyroid Chinese population aged 40 years and above.
这项横断面研究调查了40岁及以上甲状腺功能正常的中国人群中甲状腺激素与外周动脉疾病（PAD）之间的关系。测量了血清游离三碘甲状腺原氨酸（FT3）、游离甲状腺素（FT4）、促甲状腺激素（TSH）和甲状腺抗体。PAD定义为踝臂指数（ABI）<0.9。在3148名甲状腺功能正常的研究参与者中，有91例（2.9%）PAD病例。与最低四分位数的参与者相比，FT3和游离三碘甲状腺原氨酸与游离甲状腺素比值（FT3/FT4比值）最高四分位数的参与者患现患PAD的风险降低（多变量调整比值比，95%置信区间：分别为0.32，0.15 - 0.62，趋势P = 0.01；以及0.31，0.13 - 0.66，趋势P = 0.004）。总之，在40岁及以上甲状腺功能正常的中国人群中，FT3水平和FT3/FT4比值与现患PAD呈负相关。
