RESUMO
Nonatherosclerotic spontaneous coronary artery dissection (NA-SCAD) is an uncommon cause of myocardial infarction. It most commonly affects females in the perimenopausal age. NA-SCAD has been associated with many predisposing factors including pregnancy and hormonal therapy for both contraception and ovulation induction. The presented case is a previously healthy 41-year-old woman diagnosed with inferior ST-elevation myocardial infarction due to right descending coronary artery dissection associated with recent use of clomiphene monotherapy for ovulation induction (a previously fertile woman), which was not previously reported. Learning Objectives. Emergency physicians (EPs) should be aware about NA-SCAD as a cause of acute coronary syndrome (ACS) especially in perimenopausal women even with no risk factors. NA-SCAD occurs more commonly in the postpartum period and in females following hormonal therapy. Here, clomiphene monotherapy was reported as a possible contributing factor to NA-SCAD. Guidelines for NA-SCAD management are not up to date, and EPs should avoid some interference before the final diagnosis of the cause of myocardial infarction.
