THE INFLUENCE OF COMBINED CARDIOPULMONARY PATHOLOGY ON THE QUALITY OF LIFE OF PATIENTS AND THEIR MOTIVATION TO TREATMENT

Abstract

The aim of the study was to investigate the effect of chronic obstructive pulmonary disease (COPD) associated with coronary heart disease (CHD) on the quality of life (QL) of patients and their motivation to treatment. QL was studied in 136 patients with COPD associated with CHD (the main group), 56 patients with COPD (1^st group) and 60 patients with CHD (2^nd group). The average age of the patients was 55.4±2.2 years old, COPD duration was 13.1±2.1 years, CHD duration was 7.2±3.4 years, smoking history was 22.1±2.5 pack/years. To assess the QL, there were used Russian versions of QL questionnaires: standard "Brief medical questionnaire" (Medical Outcome Study SF-36) and specialized "Respiratory Questionnaire of St. George’s Hospital" (SGRQ). The motivation for treatment in the main group was assessed by the standard test-questionnaire MSF (Motivation for success and motivation for the fear of failure). It was found out that the patients of the main group by the majority of scales of the questionnaire SF-36 had a significant reduction in variables reflecting both physical and social health. According to the specialized questionnaire SGRQ, the specific health in patients with COPD, combined with CHD, suffered to a greater extent, which was proved by higher values of the scale "Total" in the main group against the 1^st comparison group (by 20.9%; p<0.01) and 2^nd comparison group (by 31.1%; p<0.001). According to MSF questionnaire, the proportion of patients in the main group with a "failure, and closer to treatment failure" was 57.4%. Thus, it was found out that the association of COPD and CHD is a significant factor in determining the intensiveness of decline of QL of patients and their motivation for successful treatment.
