Thyroid functional disease is associated with clinically significant cardiovascular changes. The aim of this study was to assess changes in the cardiac magnetic resonance imaging of patients with autoimmune thyroid disorders (AITs).
Forty patients with AIT (12 men, 28 women; age range, 20 to 82 y; mean age, 59 y) were identified and included in our study. In addition, 20 controls (12 men, 8 women; age range, 21 to 76 y; mean age, 50 y) without AIT or cardiac disorders were included.
In patients with AIT, the mean value calculated for the end diastolic volume was 161.2 mL, the mean end systolic volume value was 95.3 mL, and the mean left ventricular ejection fraction value was 45.2%. In comparing AIT patients with the control group, we found a significant difference in the end systolic volume, ejection fraction, stroke index, cardiac output, cardiac index, and left ventricular diameter (P<0.05).
We conclude that our data show that there is a correlation between thyroid function and cardiac function, as evaluated with cardiac magnetic resonance imaging. This can be useful in the diagnosis of cardiovascular changes associated with AIT.
甲状腺功能疾病与临床显著的心血管变化有关。本研究旨在评估自身免疫性甲状腺疾病（AIT）患者心脏磁共振成像的变化。
我们确定并纳入了 40 名 AIT 患者（12 名男性，28 名女性；年龄 20 至 82 岁，平均年龄 59 岁），并纳入了 20 名无 AIT 或心脏疾病的对照者（12 名男性，8 名女性；年龄 21 至 76 岁，平均年龄 50 岁）。
AIT 患者的舒张末期容积平均值为 161.2mL，收缩末期容积平均值为 95.3mL，左室射血分数平均值为 45.2%。与对照组相比，AIT 患者的收缩末期容积、射血分数、stroke index、心输出量、心指数和左心室直径存在显著差异（P<0.05）。
我们的数据表明，甲状腺功能与心脏功能之间存在相关性，可通过心脏磁共振成像进行评估。这对于诊断与 AIT 相关的心血管变化可能具有重要意义。
