Spontaneous coronary artery dissection (SCAD) is a rare but potentially life-threatening condition if it goes unrecognized. Symptoms can range from chest pain to sudden cardiac death. We present a case of 33 year-old female marathon runner who presented to emergency department (ED) complaining of sudden onset of non-positional, constant, pleuritic chest discomfort. She was eventually found to have spontaneous dissection of coronary artery. The mimicking nature of SCAD is presented in this article. We conclude that spontaneous coronary dissection, although still challenging due to its mimicking nature, should be considered in the differential diagnosis of chest pain and associated myocardial injury.
