Myocardial infarction caused by Graves' disease.

Coronary artery spasm is a rare cause of the myocardial infarction (0,5 % of cases). It can be also complicated by dysrhythmia or sudden cardiac death. We present a case of 41-year-old woman with non-ST elevation myocardial infarction caused by coronary artery spasm associated with hyperthyroidism. The coronarography showed a spasm of the left cardiac artery witch completely relieved by administration of intra coronary nitrate. In the course of the further research the patient was diagnosed with the Graves’s disease.
