Myocardial infarction in a pre-menopausal woman with angiographically normal coronary arteries.

A young pre-menopausal non-drug-addict woman without risk factors for coronary artery disease suffered from a non-Q-wave acute myocardial infarction. She presented with epigastric pain and vomiting. Diagnosis of acute myocardial infarction was not suspected at first because of her young age and lack of risk factors. She was treated for gastritis but worsening of epigastric pain and its radiation to chest warranted the diagnosis of acute myocardial infarction, which was confirmed by serial serum cardiac enzymes. Subsequent coronary angiogram revealed normal coronary arteries.
