Background and Aim: Human health has a close relationship with sleep quality and quantity. The aim of the present study was to determine sleep quality in the elderly suffering from cardiovascular disorders. 
Materials and Methods: A descriptive cross-sectional study was conducted on 147 patients suffering from coronary artery disease who visited Imam Ali hospital in Kermanshah city. Data collection was performed using Pittsburgh sleep inventory and Beck’s depression inventory. Descriptive statistics and Pearson’s correlation test were used to analyze the data. Data analysis was performed using SPSS, version 25. 
Results: A total of 131 participants (89.1%) were observed to have poor sleep quality: 84 patients (64.1%) had a score between 5-9 which indicates mild sleep problems, 41 patients (31.2%) had a score between 10-14 which indicates moderate sleep problems, and 6 patients (4.5%) had a score between 15-21 showing severe sleep problems. Average score for all participants was 8.29±3.36 which indicates that patients suffering from coronary artery disease have poor sleep quality. Also, it was found that age and education had no significant effect on sleep quality, while parameters such as gender, body mass index, and psychological variables, including depression, anxiety, and rumination, were correlated with sleep quality (P<0.05). 
Conclusions: Our results demonstrated that coronary disease patiets suffer from poor sleep quality.Also, since psychological variables, such as depression and anxiety, had a correlation with sleep quality, preventive actions are required to mitigate these psychological issues.
