Cocaine-induced postpartum coronary artery dissection: a case report and 80-year review of literature.

The incidence of cocaine-induced myocardial infarction (MI) in pregnancy is unknown. During the peripartum period, cocaine-abusing women are highly susceptible to MI caused by the effect of cocaine on a heart that is already stressed by hemodynamic changes of pregnancy. MI is an infrequent event during pregnancy and the peripartum period, with an estimated rate of 1 in 16,000 patients. Spontaneous coronary artery dissection (SCAD) can account for up to 27% of pregnancy-related MIs. We describe a case of MI diagnosed by increased troponin I levels in a postpartum patient with recent crack cocaine use in the setting of SCAD that required percutaneous coronary intervention of the left anterior descending and diagonal arteries. We also provide a comprehensive review of published literature related to this clinical entity.
