【摘要】 背景 糖尿病心脏自主神经病变(DCAN)是糖尿病常见且严重的慢性并发症之一,但目前关于甲状
腺功能与 DCAN 关系的研究报道较少。目的 探讨亚临床甲状腺功能减退症(SCH)对 DCAN 的影响。方法 选取
2019 年 10 月至 2020 年 10 月在首都医科大学附属北京友谊医院住院及门诊就诊的 2 型糖尿病患者 564 例。所有患者
均完成 Ewing 试验。收集患者一般资料、体格检查结果、实验室检查结果,并依据 Ewing 试验评估并筛查 DCAN。相
关性分析采用 Pearson 相关分析和 Spearman 秩相关分析,采用多因素 Logistic 逐步回归分析探究 2 型糖尿病患者并发
DCAN 的影响因素。结果 564 例 2 型糖尿病患者中,129 例并发 DCAN(DCAN 组),435 例未并发 DCAN(对照组),
DCAN 发生率为 22.9%。2 型糖尿病患者中合并 SCH 者 84 例(14.9%),DCAN 组患者中合并 SCH 者 36 例(28.0%),
2
对照组患者中合并 SCH 者 48 例(11.0%),DCAN 组患者合并 SCH 患病率高于对照组(χ =22.346,P<0.001)。2 型
糖尿病并发 DCAN 患者 Valsalva 试验动作期间最大 R-R 间距与最小 R-R 间距比值(VAL R-R 比值)与糖尿病病程、
糖化血红蛋白(HbA 1c )、空腹血糖(FBG)、低密度脂蛋白胆固醇(LDL-C)、三酰甘油(TC)、超敏 C 反应蛋白
(hs-CRP)、促甲状腺激素(TSH)、尿微量白蛋白 / 肌酐(UACR)呈负相关,与舒张压(DBP)呈正相关(P<0.05)。
多因素 Logistic 逐步回归分析结果显示,SCH〔OR=1.717,95%CI(1.246,2.365)〕是 2 型糖尿病患者并发 DCAN 的
独立影响因素(P<0.05)。结论 2 型糖尿病患者 TSH 水平与 DCAN 相关,且 SCH 是 2 型糖尿病患者并发 DCAN 的
独立影响因素。

【Abstract】 Background Cardiac autonomic neuropathy (CAN) is a common and severe chronic diabetic
complication,whose association with thyroid function has rarely been reported. Objective To investigate the association between
subclinical hypothyroidism and CAN in type 2 diabetes mellitus(T2DM). Methods We performed a retrospective analysis
of 564 outpatients and hospitalized patients with T2DM recruited from Beijing Friendship Hospital,Capital Medical University
from October 2019 to October 2020. Baseline characteristics,physical and laboratory examination results were collected. Ewing
test was performed to identify CAN. The association between subclinical hypothyroidism and CAN was assessed using the Pearson
correlation coefficient and Spearman's rank coefficient of correlation. Factors associated with CAN in T2DM were identified using
multivariate,stepwise logistic regression. Results One hundred and twenty-nine subjects (22.9%) were found with CAN,
and other 435 without. Subclinical hypothyroidism was detected in 84 cases(14.9%),including 36 with CAN and 48 without.
The prevalence of subclinical hypothyroidism in those with CAN〔28.0%(36/129)〕 was higher than that of those without〔11.0%
2
(48/435)〕(χ =22.346,P<0.001). For those with CAN,the ratio between maximum and minimum R-R intervals during
the Valsalva maneuver demonstrated a negative correlation with the duration of T2DM,glycated hemoglobin,fasting plasma
