Current management of spontaneous coronary artery dissection

ABSTRACT Introduction: Spontaneous coronary artery dissection (SCAD) remains an infrequent and elusive clinical entity of unknown etiology. However, our knowledge of SCAD has been significantly enriched in recent years. Large and prospective contemporary series have increased the interest in this disease with fewer patients misdiagnosed and a growing number of cases recognized in daily clinical practice. Classically, SCAD was thought to present mainly in young women without traditional atherosclerotic risk factors but, actually, most patients are middle-aged and are not free from coronary risk factors. A high number of associated conditions have been reported. Of these, fibromuscular dysplasia emerges as a major association with intriguing pathophysiological implications. Areas covered: This review aims to present a contemporary update on SCAD. We concentrate on the clinical scenario, related conditions, practical management and treatment strategies. Expert commentary: Recognition of SCAD is currently much more frequent and accurate as a result of increased clinical awareness and the widespread use of intravascular imaging techniques. Hopefully, in the near future an improvement in the management of SCAD patients will come not only from empirical evidence but also from dedicated clinical trials.
