The paper presents the study of the relationship between the attitude to the disease, coping behavior of patients with coronary heart disease prior to coronary bypass grafting (CABG), and indicators of cognitive status. Bekhterev Institute Personality Questionnaire, Ways of Coping Behavior test by R. Lazarus, Mini-Mental State Examination scale, Frontal Dysfunction Battery test, and Clock- Drawing test were used in the study. The sample included 132 patients. The results of study show that in patients with coronary artery disease prior to CABG the most frequently observed type of attitude to the disease is either the harmonious type or a combination of harmonious and ergopathic types. Confrontation, Distancing, and Problem Solution Planning were identified as the preferred coping strategies. Correlation analysis revealed positive associations between cognitive status and harmonious, ergopathic, and hypochondriac types of attitude to the disease, and negative associations between cognitive status and anosognostic and sensitive types of attitude to the disease. Furthermore, positive correlations between cognitive status and Confrontation, Self-control, Responsibility taking, Problem Solution Planning, Positive revaluation coping strategies and negative correlations between cognitive status and Distancing and Escape-avoidance coping strategies were found. The results of this study will help to improve the level of diagnostic and rehabilitation psychological care of patients with coronary artery disease in preparation for CABG.
