Myocardial infarction in a premenopausal woman with a decreased serum estrogen level due to leuprorelin acetate

A 45-year-old premenopausal woman was admitted with acute myocardial infarction. Her serum estrogen level was decreased because of leuprorelin acetate administration, 3 months prior to admission for the treatment of uterine myoma. Emergency coronary angiography revealed diffuse narrowing of the distal half of the left anterior descending artery (LAD). The second coronary angiography after anti-anginal medication revealed significant improvement in LAD narrowing, which suggested prolonged coronary vasospasm. She had no coronary risk factors except for a positive family history. This case suggests that a decreased serum estrogen level could cause ischemic heart disease even in premenopausal women.
