Spontaneous Coronary Artery Dissection in a 27-Year-Old Woman

BackgroundSpontaneous coronary artery dissection (SCAD) causes acute coronary syndromes or sudden death in young patients who are often lacking classic coronary disease risk factors. Systemic inflammatory and connective tissue diseases have been suggested as risk factors for SCAD.ObjectiveTo review the risk factors, diagnosis, and management of this uncommon but life-threatening disease.Case ReportWe report a case of a 27-year-old woman with a history of an ill-defined inflammatory arthropathy who presented with an acute ST-elevation myocardial infarction. SCAD was diagnosed by coronary angiography. Percutaneous coronary intervention was attempted but was unsuccessful. The patient recovered uneventfully with medical management and was ultimately diagnosed with systemic lupus erythematosus.ConclusionsSCAD is a rare but important cause of acute coronary syndromes and sudden death. It commonly occurs in young women. Although pregnancy is the most well-established risk factor, systemic inflammatory and connective tissue diseases have also been suggested as risk factors.
