АФФЕКТИВНЫЕ РАССТРОЙСТВА И КАЧЕСТВО ЖИЗНИ У БОЛЬНЫХ КОРОНАРНОЙ БОЛЕЗНЬЮ СЕРДЦА ПО ДАННЫМ ПСИХОМЕТРИЧЕСКИХ ТЕСТОВ

The aim was to study the frequency and severity of affective disorders and quality of life in patients with coronary heart disease (CHD): unstable and stable angina of II–III functional class. Materials and methods. 488 patients with verified CHD were examined to identify and assess anxiety-depressive spectrum disorders by the screening questionnaire of Moscow Research Institute of Psychiatry, Ministry of Health of Russia. 172 patients with CHD from the screening group – 96 (55.81 %) patients with unstable angina and 76 (44.19 %) with stable angina, 136 (79.07 %) men and 36 (20.93 %) women were examined with psychometric tests: Hospital Anxiety and Depression Scale (HADS) and Beck Depression Inventory (BDI). Modified Seattle Angina Questionnaire (SAQ) was used to study quality of life. Excel and Statistica 6.0 programs were used to assess statistical process of the material. Results. According to the screening questionnaire, in screening group of patients with CHD (n = 488) the symptoms of anxiety-depressive disorder were present in 398 (81.56 %) patients, in 90 patients (18.44 %) they were absent (p <0.0001). In the group of patients with CHD examined by psychometric tests (n = 172), the symptoms of anxiety-depressive disorder according to the screening questionnaire were revealed in 137 (79.65 %) patients, in 35 (20.35 %) patients they were absent (p <0.0001). The severity of depression symptoms according to BDI scale (17.11 ± 9.38 vs. 12.73 ± 8.1 points; p <0.04) and the symptoms of anxiety-depressive disorder according to the screening questionnaire were noted more often (p <0.0008) in patients with unstable angina compared with stable angina – in 85 (88.54 %) vs. 52 (68.42 %) patients (р <0.0008). In the group of patients with stable angina the level of depression according to BDI scale in patients taking pharmacological treatment was higher in comparison with the patients who underwent myocardial revascularization (14.56 ± 9.0 vs. 10.03 ± 6.13 points; p <0.01). Quality of life parameter according to modified SAQ was statistically significantly decreased in the subgroups of patients with increasing severity of depression symptoms according to BDI scale (10–63 points) compared with the subgroup of patients with no depression (0–9 points). Conclusion. According to the screening questionnaire, a high incidence of anxiety-depressive disorder was found in patients with CHD. The symptoms of anxiety-depressive disorder and the severity of depression symptoms according to BDI scale were noted more often in the group of patients with unstable angina compared with the group of patients with stable angina. Quality of life parameter according to modified SAQ was statistically significantly reduced with increasing severity of depression symptoms according to BDI scale in subgroup of patients with symptoms of depression compared with the subgroup of patients without depression. According to the results of the study the BDI scale is more sensitive for the diagnosis of depression than the HADS scale.
