Spontaneous Coronary Artery Dissection in a Pre- Menopausal Woman Occurring Just prior to Menstruation

Spontaneous coronary artery dissection (SCAD) is a rare cause of myocardial infarction. It is known to occur in young women in the peripartum period. The exact aetiology is unknown. This report describes a 46 year old pre-menopausal woman without cardiac risk factors presenting with acute inferior myocardial infarction and SCAD angiographically. She was noted to be at the end of her menstrual cycle. We believe that her SCAD was directly related to the phase of menstrual cycle she was in.
