Sleep Quality, Anxiety, and Depression in Patients With Heart Failure

Heart Failure (HF) is a chronic condition with great impact on the lifestyle of the patients. As many as 80% of HF patients report experiencing sleep difficulties. Thus, we try to detect clinical predictors of sleep quality and define probable relationship between anxiety, depression, and sleep quality in HF patients.Materials & One hundred patients (male: 50 persons, female: 50 persons) with ejection fraction less than 45% who were hospitalized in CCU and post-CCU ward, were included in this study. Hospital Anxiety and Depression Scale (HADS) and Pittsburg Sleep Quality Index (PSQI) questionnaire were used to collect the related data. The patients’ mean (SD) total PSQI score was 9.07(4.43). The most problem was seen in sleep onset latency (1.85[1.15]) sub-score of PSQI and the sleep quality of 78% of patients was abnormal. This score was higher in patients with history of abnormal blood pressure (P=0.001). PSQI score have significant correlation with anxiety (r=0.216, P=0.035) as well as depression (r=0.351, P=0.000). Many HF patients suffer from sleep difficulties and PSQI score seems to have significant correlation with anxiety and depression.
