ارتباط بین ادراک بیماری و کیفیت زندگی بیماران پس از جراحی بای پس عروق کرونری

Background and purpose: Low health related quality of life is one of the most important consequences of diseases. Patients’ believes about different aspects of new situation influences the consequences of illness and their quality of life. This study aimed at investigating the relationship between illness perceptions and quality of life after coronary artery bypass graft surgery (CABG). Materials and methods: In a cross-sectional survey research, 102 patients were studied after CABG in Alzahra Hospital in Shiraz. Patients were selected according to convenience sampling. Illness Perception Questionnaire (IPQ) and global Quality of Life questionnaire (WHOQOL-BREF) were used to collect the data. Results: Significant association was observed between patient’s illness perception and quality of life. Among illness perception subscales, time line (r= 0.501, P< 0.001), causal representation (r= 0.210, P< 0.05), illness coherence (r= 0.210, P< 0.05), personal control (r= 0.467, P< 0.001), treatment control (r= 0.380, P< 0.001), and emotional representations (r= 0.312, P< 0.001) had the most significant correlation with quality of life. Also, quality of life was significantly associated with sex (P<0.001), level of education (P<0.03) income (P<0.001), and occupation (P< 0.001). Conclusion: Illness perception about coronary artery disease has significant effects on disease outcomes and quality of life of patients after treatment. Therefore, psychological interventions focusing on this factor are recommended in involved patients.
