Significance of resting state electroencephalogram for diagnosis of cognitive disorders in cardiac surgery patients

This article reviews the issues of cognitive disorders common in cardiac surgery patients as they contribute to the structure of postoperative complications and the long-term prognosis of cardiovascular diseases. Attention is drawn to the fact that the diagnostic capabilities to assess the changes in cognitive status of cardiac surgery patients are limited; and the authors emphasize the need to search for objective and sensitive criteria for diagnosis of cognitive disorders in patients, candidates to direct myocardial revascularization. Relevance of the modern methods for brain electrical activity mapping to study neurophysiological status of patients with coronary artery disease undergoing cardiac surgery interventions is evaluated.
