Management of patients with concomitant coronary and carotid artery disease

Introduction: Ideal management of concomitant carotid and coronary artery occlusive disease remains under investigation. Although researchers have advocated the potential benefits of varying treatment strategies based on either concomitant or staged surgical treatment, there is no consensus in treatment guidelines. With emerging data suggesting favorable outcome of carotid artery stenting (CAS) compared to carotid endarterectomy (CEA) in patients with critical coronary artery disease, physicians must consider these diverging therapeutic options.Areas covered: This review presents current evidence regarding the prevalence of carotid stenosis in patients with coronary artery disease, the common pathophysiologic links with an emphasis on the diverse mechanisms of stroke in the coronary artery bypass grafting (CABG) setting and discusses the contemporary registries and observational studies comparing outcomes of various revascularization strategies in high-risk patients. Authors conducted a literature search in two bibliographic databases including papers published from 1983 until 2018 (PubMed, Scopus).Expert opinion: Symptoms should drive the need to intervene on carotid stenosis in patients undergoing coronary revascularization. Carotid artery stenting has gained significant ground, especially among those individuals considered of high surgical risk. PCI may be considered as an alternative option for the management of severe concurrent coronary disease.
