Abstract: Objective · To explore the correlation of anxiety and depression with sleep quality and quality of life in elderly patients with percutaneous coronary intervention (PCI). Methods · A total of 297 elderly patients undergoing PCI were surveyed according to hospital anxiety and depression scale (HADS), Piusburgh sleep quality index (PSQI) and 12-item short form health survey version 2.0 (SF-12v2) on the day before they were discharged two hospitals (Xinhua Hospital, Shanghai Jiao Tong University School of Medicine and Shanghai Sixth Peoples Hospital, Shanghai Jiao Tong University). All data was based on their subjective feelings in the past month. Spearman correlation analysis was performed on the scores of anxiety and depression to sleep quality and life quality. The multiple linear regression was used to analyze the influencing factors of life quality. Results · 21.5% of the patients were assessed as anxiety positive, and 22.2% were assessed as depression positive, both higher than those of the patients in general hospitals of China (both P0.000). The average score of patients sleep quality was 6.50±3.46, which was higher than the domestic norm (P0.000). The average score of patients quality of life was 132.20±30.83, the physiological score was 60.44±17.58, and the psychological score was 71.76±15.96. Correlation analysis showed that there was a significant positive correlation between total scores of anxiety and depression and total scores of sleep quality (P0.026, P0.027), and a significant negative correlation between total scores of anxiety and depression and total quality of life scores, the physiological scores and the psychological scores (all P0.000). The linear regression equation of anxiety and depression scores and quality of life scores in elderly patients with PCI was significant (P0.000, R20.246). Conclusion · The incidence of anxiety and depression in elderly PCI patients was high in the last month before admission, and the sleep was poor. The more obvious the anxiety or depression, the worse the quality of sleep and quality of life. Attention should be paid to the relations of anxiety and depression to sleep quality and quality of life, and efforts should be made to improve the negative emotions of patients and enhance their sleep quality and quality of life.
