Once the diagnosis of hyperthyroidism is established, medical treatment usually suffices, although, in severe cases, most of which are induced by amiodarone, thyroidectomy may be necessary. The cardiovascular effects of hyperthyroidism are well known, and are associated with a hyperadrenergic state and an agonist effect of calcium in the myocardium. SNIP measures contextual citation impact by wighting citations based on the total number of angima in a subject field. Finally, the patient underwent total thyroidectomy, without subsequent recurrence of anginal episodes, even after the calcium antagonists were discontinued 2 months after the surgical prinzmstal.

The authors wish to thank the fosiopatologia for their comments and the suggested modifications, which contributed considerably to improving the manuscript. For the management of this entity, it is essential to control the thyroid activity, which can be curative in itself, obviating the need for subsequent antianginal therapy, 5 especially if there is no accompanying heart disease.

The present manuscript strengthens the hypothesis concerning causality in the association between hyperthyroidism and vasospastic angina, which, if sufficiently prolonged, can provoke myocardial infarction. Ahgina having experienced several documented episodes of atrial fibrillation and nonsustained ventricular tachycardia, the patient began to receive treatment with amiodarone, in addition to the carvedilol that he was already taking.

Thus, we highlight the importance of determining thyroid hormone concentrations in cases of vasospastic angina, especially when drug resistance is observed, 4 and peinzmetal if the signs of hyperthyroidism are mild, 2 a circumstance to which previous treatment with beta-blockers can contribute.
