Does hyperthyroidism cause coronary vasospasms

We report a 62-year-old women with atypical chest pain who had catheter-induced vasospasms during which she experienced the same type of chest pain she had before hospital admission. In addition, she was found to have hyperthyroidism and was discharged on methamizole and a beta blocker. Within a few weeks, TSH, fT3, and fT4 normalised, and she did not have recurrent chest pain. Summarising our case report and the existing literature, it appears likely that hyperthyroidism causes coronary vasospasms at least in a subset of patients and therefore, we believe that hyperthyroidism should be ruled out in patients with chest pain that is thought to be secondary to vasospasms.
