THE DYNAMICS OF COGNITIVE FUNCTIONS IN PATIENTS WITH CHD DURING REHABILITATION AFTER CORONARY BYPASS SURGERY: METHODOLOGY AND PRELIMINARY RESULTS OF THE STUDY
Abstract
The article presents an analytical review of modern literature on neurocognitive deficits among cardiac patients. It is shown that bypass surgery is associated with high risk of both operational and postoperative
cognitive disorders. This fact determines the importance of identifying the factors that lead to deterioration of patients’ cognitive functioning in the nearest and late postoperative periods. Therefore the authors have developed a program of a complex dynamic study of the cognitive dysfunction in patients, its relationship to emotional characteristics and personality, adherence to treatment, clinical indicators of the patient’s condition and the characteristics of the surgery performed, as well as the relationship between the complex of psychological and clinical characteristics, and the effectiveness of postoperative rehabilitation, including social and labor recovery of patients. A research program, based on the “Statement of consensus on assessment of neurobehavioral outcomes aft er cardiac surgery”, is presented in the paper. The preliminary results of cognitive functions study in 70 patients with CHD, which was carried out before coronary bypass surgery, during the patients’ rehabilitation in hospital (12–14 days aft er surgery) and 3 months after surgery (outpatient basis), are presented. It was found that patients’ cognitive function dynamics during rehabilitation after bypass surgery manifests differently in distinct cognitive functions (sensorimotor functions, cognitive control and proactive attention, perception, memory and thinking). The following steps of the comprehensive study suggest the ascertainment of the relationship of the characteristics of patients’ cognitive functioning after bypass surgery with the efficiency of cardiorehabilitation, medical and social prognosis of patients.
