Prediction of Quality of Life Based on Anger, Depression, Anxiety, Spousal Intimacy, and Sexual Satisfaction in Iranian Patients Undergoing Coronary Artery Bypass Surgery

Abstract

Background: Psychological consequences following coronary artery bypass graft (CABG) surgery, such as anger, depression, anxiety, spousal intimacy, and sexual satisfaction, significantly impact patients' quality of life (QOL). Given the increasing prevalence of heart disease, understanding these factors is essential for post-surgical care and recovery. Objectives: This study aimed to investigate the predictive role of psychological and relational factors in determining the QOL of patients undergoing CABG. Methods: A cross-sectional study was conducted with 130 patients who had recently undergone CABG at Ayatollah Taleghani Hospital in Tehran. Standardized self-report questionnaires assessed psychological and relational factors, including the Quality of Life Scale (SF-36), Aggression Questionnaire (AGQ), Depression Anxiety Stress Scale-21 (DASS-21), Walker-Thompson Intimacy Scale (MIS), and Larson's Sexual Satisfaction Questionnaire (LSSQ). Pearson's correlation and multiple regression analyses examined the relationships among variables, controlling for demographic factors such as age and education level. Results: Depression (R = -0.637), anxiety (R = -0.669), and sexual satisfaction (R = 0.59) were significant predictors of QOL, while anger (R = -0.371) and spousal intimacy (R = 0.459) did not demonstrate a significant impact. The regression model accounted for 59.5% of the variance in QOL (P < 0.01). Findings suggest that psychological distress plays a stronger role in predicting QOL than relational factors in post-CABG patients. Conclusions: Findings indicate that depression, anxiety, and sexual satisfaction significantly play key roles in determining the QOL of CABG patients. Implementing psychological interventions aimed at reducing depression and anxiety while enhancing sexual satisfaction may significantly improve postoperative well-being. Integrating these strategies into patient care could enhance recovery and QOL after CABG.
