甲状腺疾病与脑血管病

Thyroid Diseases and Cerebrovascular Diseases

在甲状腺功能亢进患者中，脑栓塞与甲状腺毒性心房颤动存在显著的相关性；在血清促甲状腺激素水平〈0．1mU／L的亚临床甲状腺功能亢进患者中，毒性心房颤动的发生率亦显著增高。甲状腺功能亢进可能导致脑静脉血栓形成、烟雾病和巨细胞动脉炎；而甲状腺功能减退则与动脉粥样硬化的危险因素，尤其是高血压、高脂血症和高同型半胱氨酸血症有密切关系。但在亚临床甲状腺功能亢进患者中，这种联系尚不明确。

There are significant correlations between cerebral embolism and thyrotoxic atrial fibrillation in patients with hyperthyroidism. The incidence of thyrotoxic atrial fibrillation increases significantly in patients with subclinical hyperthyroidism with serum thyroid-stimula- ting hormone levels 〈 O. 1 mU/L. Hyperthyroidism may result in cerebral venous thrombosis, moyamoya disease and giant cell arteritis; while hypothyroidism is closely associated with the risk factors of arteriosclerosis, especially hypertension, hyperlipidemia, and hyperhomocysteinemia. However, this association remains uncertain in subclinical hyperthyroidism.
