Spontaneous coronary arterial dissection (SCAD) has become an important cause of acute coronary syndrome (ACS) and sudden cardiac death, particularly in young women, without classic atherosclerotic cardiovascular risk factors. Missed diagnosis is common due to a low index of suspicion in these patients. Here, we present a case of a 29-year-old African female in the postpartum period who presented with a two-week history of heart failure symptoms and acute onset chest pain. An electrocardiogram showed ST-segment elevation myocardial infarction (STEMI) with elevated high-sensitivity troponin T. Echocardiography on admission revealed an ejection fraction of 40% with septal hypokinesia. Coronary angiography showed multivessel dissection with type 1 SCAD in the left circumflex artery and type 2 SCAD in the left anterior descending artery. The patient was managed conservatively, and angiographic healing of SCAD together with normalization of the left ventricular systolic dysfunction was seen after four months. SCAD should always be in the differential diagnosis of any peripartum patient who presents with ACS and lacks the typical atherosclerotic risk factors. Accurate diagnosis and appropriate management are paramount in such cases.
