SCAD warrants consideration in acute aortic dissection differentials; single case leaves hypertension's pathogenic role hypothesis-generating.
Spontaneous coronary artery dissection is a rare cause of acute coronary syndrome or sudden cardiac death, occurring predominantly in the female sex without cardiovascular risk factors. Although the etiology and pathogenesis remain uncertain, hypertension has not appeared to be one of the most important factors. This case report describes a patient with spontaneous coronary artery dissection in proximal right coronary artery who presented the signs and symptoms of acute aortic dissection. The authors postulate that hypertension may have been an important factor for the pathogenesis of the spontaneous coronary artery dissection.
