Comparison of Depression and Quality of Life after Coronary Artery Bypass Graft Surgery in Patients With and Without Type D Personalities

Background: Recently, some studies have investigated type D personality as a critical factor in developing depression and reducing the quality of life. Objectives: This study aimed to compare depression and quality of life after coronary artery bypass graft surgery in patients with and without type D personalities. Methods: Sixty-nine participants who underwent coronary artery bypass grafting at Imam Khomeini hospital, Ahvaz, Iran, referred to the cardiac surgery clinic for their first visit (1 to 1.5 months after surgery) were included in the study. All participants completed the World Health Organization Quality of Life questionnaire, type D personality scale, and Beck’s Depression Inventory. Finally, depression and quality of life were compared in two groups with and without type D personalities using ANOVA and correlation tests. Results: The two groups were significantly different in depression and quality of life scores after coronary artery bypass graft surgery. Depression and quality of life impairment were higher in participants with type D personality. There was no significant relationship between depression and quality of life with age, gender, and occupation in participants with type D personality. Conclusion: Depression and quality of life were higher in patients with type D personality after coronary artery bypass graft surgery than patients without type D personality. Episodic screening of these patients can prevent future somatic and psychological problems.
