冠状动脉痉挛可在α -肾上腺素能张力过高时发生。保护性冠状动脉血管扩张剂物质的减少和α -肾上腺素能反应性的增强，发生在甲状腺功能减退和β阻断的情况下，容易发生冠状动脉痉挛。所提出的案例支持这些概念。
Coronary artery spasm can occur in the presence of excessive alpha-adrenergic tone. A decrease in protective coronary vasodilator substance and enhanced alpha-adrenergic responsiveness, which occurs in the setting of hypothroidism and beta blockade, predisposes to coronary artery spasm. The case presented supports these concepts.
