Spasme coronaire secondaire à la thyrotoxicose : quelles leçons à retenir ?

Coronary spasm related to thyrotoxicosis is a complication rarely reported in the literature. Its initial clinical presentation is often more severe with more diffuse involvement and resistance to medical treatment compared to classic coronary spasm. Its diagnosis relies on a careful clinical analysis and a comparative study of electrocardiographic data. Coronary angiography should be avoided as much as possible as well as treatment by nonselective beta-blocking agents because of the risk of worsening hyperthyroidism and coronary vasoconstriction. We report a case of coronary spasm secondary to Graves' disease whose management was inspired by lessons learned from clinical cases reported in the literature. [ABSTRACT FROM AUTHOR]
