Two case reports of spontaneous coronary dissection

Abstract

Spontaneous coronary artery dissection (SCAD) has nowadays been described as a non-negligible etiology of acute coronary syndromes (ACS). Its prevalence approximates 3% in most cohorts. It mainly affects women in the young to middle-aged range. Individuals with SCAD typically exhibit fewer conventional cardiovascular risk factors associated with ischemic heart disease compared to those with atherosclerotic coronary artery disease. Nevertheless, some SCAD patients may present with risk factors such as hypertension, smoking, and dyslipidemia, although their direct contribution to SCAD risk remains uncertain. We present two cases of spontaneous coronary dissection to explore its pathogenesis, diagnosis, and treatment options. Learning objectives · Recognize spontaneous coronary artery dissection as the possible cause of ACS in females even with cardiovascular risk factors. Learn the importance of angiographic control after a conservative therapy that may lead to a more invasive approach.
