Speaking about patients who are referred for carotid endarterectomy (CEE), we must remember that not all of them have isolated stenoses of the internal carotid arteries (ICA).1, 2, 3, 4, 5 According to a number of studies, in a significant proportion of patients requiring CEA, coronary lesions are visualized, which raises the question of the need for myocardial revascularization.6, 7, 8, 9, 10 How dangerous it is to perform CEE in a sample of patients with severe coronary atherosclerosis relative to those who have differentiated insignificant stenoses of the coronary arteries, according to current recommendations, is determined by a multidisciplinary council personalized for each patient (class 1, level of evidence C).1,5

The existing problems in the evidence base do not demonstrate a complete picture of the risks when performing CEA in patients with varying severity of coronary atherosclerosis.11, 12, 13, 14, 15 It is necessary to understand whether any additional measures are needed to prevent postoperative complications or whether a standard management protocol is sufficient. The risks of possible cardiovascular events in the long-term period have not been fully determined, as well as the factors that influenced its severity in different samples of patients.1

The purpose of this work was to analyze in-hospital and long-term postoperative complications after CEA in patients with different severity of coronary atherosclerosis according to SYNTAX SCORE.
