Thyrotoxicosis-Induced Vasospastic Angina | Revista Española de Cardiología (English Edition)

Iberoamerican Cardiovascular Journals Editors’ Network. The patient was a year-old man with dilated cardiomyopathy and angiographically normal coronary arteries in 2 prior catheterizations. The cardiovascular effects of hyperthyroidism are well known, and are associated with a hyperadrenergic state and an agonist effect of calcium in the myocardium.

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

One year after the initiation of this medication, he was admitted to the hospital with unstable angina, with mild electrical and enzymatic changes.

Thyrotoxicosis-Induced Vasospastic Angina

The present manuscript strengthens the hypothesis concerning causality in the association between hyperthyroidism and vasospastic angina, which, if sufficiently prolonged, can provoke myocardial infarction.

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, prinzmetap especially if there is no accompanying heart disease. Three months after the procedure, he was readmitted with unstable angina after detection of transient precordial ST elevation and slight enzymatic elevation.

September Fisiopatolofia The atenolol that had originally been prescribed was discontinued. Continuing navigation will be considered as acceptance of this use. The authors wish to thank the reviewers for their comments and the suggested modifications, which prinzmeta, considerably to improving the manuscript.

He underwent primary angioplasty with conventional stent implantation in mid ADA. CiteScore measures average citations received per document published. A fidiopatologia catheterization ruled out complications associated with the previously implanted stentas well a development of new lesions, and the patient was discharged on calcium antagonists and nitrates.

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. SNIP measures contextual citation impact by wighting citations based on the total number of citations in a subject field. Images subject to Copyright. The episodes of angina xe rest were uncontrollable until diagnosis and proper treatment of the concomitant hyperthyroidism, the onset of which was nearly asymptomatic.


The main characteristic of the initial clinical course was the difficult management, with frequent anginal episodes, despite the use of high-dose calcium antagonists and nitrates. This item has received. The journal adheres to the standards of academic research publications in all aspects including peer-review and ethical principles.

The free thyroxine level was 6. A repeated coronary angiography revealed a diffuse, severe spontaneous spasm of anterior descending artery ADA Figure prinzjetalwhich reproduced the admission clinical onset. On the other hand, the control of hyperthyroidism proved impossible, despite the use of antithyroid prinsmetal and the discontinuation of amiodarone.

After 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. Finally, the patient underwent total thyroidectomy, without subsequent recurrence of anginal episodes, even after the calcium antagonists were discontinued 2 months after the surgical procedure. This time, coronary angiography revealed diffuse spasm in mid-distal ADA Fisiopatologiz 2fisiopatologja was controlled with intracoronary nitroglycerin.
