Hyperthyroidism-Associated Coronary Vasospasm with Myocardial Infarction and Subsequent Euthyroid Angina

摘要

A 40-year-old African-American woman presented with atypical chest pain, an acute non-ST segment elevationnmyocardial infarction, and angiographic evidence for severe ostial vasospasm of the left main and rightncoronary arteries. Subsequently, she was diagnosed with hyperthyroidism and treated with antithyroid therapynand oral nitrates. Repeat angiography revealed resolution of the vasospasm; however, the chest pain recurred innthe euthyroid state. Hyperthyroidism-associated coronary vasospasm is a rare disorder that characteristicallyncauses angina in young Asian women and resolves with correction of hyperthyroidism. We present an atypicalncase of an African-American woman presenting with a myocardial infarction who developed recurrent anginanwhile euthyroid.
