N Saydi, S Fayazi, A Ramazani


Background and Objectives: Diabetes is an important health problems that threatens patients’ quality of life (QOL). Heart disease is the most common complication of diabetes, and the most prevalent treatment for this disease is open heart surgery. Due to extensive operations of heart surgery and unpredictable effects of these interventions on the quality of life, the present study aimed at comparing the quality of life in diabetic and non-diabetic patients after open heart surgery.

Materials and Methods: This descriptive study was performed on 80 patients (31 diabetic and 49 non-diabetic) who were selected using objective-based sampling. Data were collected using SF-36 and demographic data questionnaires which were completed in 3 steps (before operation, 1 months after operation, and 3 months after operation). Data were analyzed using descriptive and analytic statistics including chi-square, repeated measures design, and the independent and paired t-test.

Findings: Results showed no significant differences between the two groups in the different dimensions of quality of life in the 1 and 3 months after the surgery. But regarding mental health and accomplishing tasks, there was a statistically significant difference (p=0.03) between the two groups three months after surgery.

Conclusion: This study showed that both diabetic and non-diabetic patients benefitted from open heart surgery, and it had improved their quality of life. Therefore, more studies are recommended to evaluate the long-term effects of open heart surgery on patients' quality of life.
