Acute myocardial infarction caused by spontaneous postpartum coronary artery dissection.
BACKGROUND
A 34-year-old postpartum woman presented at hospital with chest pain. She had experienced an uneventful delivery of a healthy infant and had no known coronary risk factors. Electrocardiography demonstrated an acute myocardial infarction, which resolved on intravenous glyceryl trinitrate infusion. Coronary angiography revealed diffuse narrowing of the left anterior descending artery and tapering of the left main trunk, but there were no obvious hallmarks of intimal dissection.


METHODS
Electrocardiography, coronary angiography, multidetector CT and intravascular ultrasonography.


METHODS
Postpartum coronary artery dissection.


RESULTS
The lesion was stabilized with orally administered amlodipine, aspirin, ticlopidine and pitavastatin, along with intravenous heparin and glyceryl trinitrate. The patient was later discharged on bisoprolol, aspirin, pitavastatin and temocapril.
