Spontaneous coronary artery dissection in a postpartum e-cigarette smoker.

Spontaneous coronary artery dissection (SCAD) is a rare but lethal cause of acute coronary syndrome that occurs in young women during the peripartum/postpartum periods. We present a case of a 41-year-old woman with no significant medical history, but was a habitual e-cigarette smoker who presented with atypical chest pain 2 weeks after an uncomplicated delivery while breast feeding. The patient was found to have elevated cardiac enzymes and ST segment elevations in the anterior leads. An urgent cardiac catheterisation was performed, which revealed dissection and occlusion of the left anterior descending artery, and a drug-eluting stent was placed that resulted in the resolution of chest pain. Physiological changes during the postpartum period may be linked to an increased risk of developing SCAD.1 In addition, e-cigarette smoking is associated with increased oxidative stress and sympathetic activity, which may predispose patients to an increased risk of acute coronary syndrome. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2018.
