Abstract

Background: Sleep disorders in patients with chronic heart failure are very common, it can significantly affect the daily activities of patients, but also have a great impact on the care and treatment of the disease, making health is declining. Purpose of the Study: This study was performed to evaluate sleep quality, its effect on patients with heart failure, and its predictors in heart failure patients. Methods: A cross-sectional descriptive study, performed on a sample size of 251 chronic heart failure patients examined and treated inpatient at Bach Mai Heart Institute from August 2021 to September 2022. These patients completed a demographic questionnaire, and their sleep quality was measured using the Pittsburgh Sleep Quality Index (PSQI). One-way analysis of variance (ANOVA), Kruskal-Wallis test, t-test and Linear regression were used for data analysis. Results: 78,5%  of patients (n = 197) reported poor sleep quality (PSQI > 5). The range of global PSQI scores was 3–19, suggesting that all patients had at least one sleep-related problem. Also, a significant relationship was found between PSQI scores and patients’ age (p<0.001), educational level (p< 0.001), occupational status (p< 0.038), number of hospitalizations (p< 0.005), non-cardiac diseases (p< 0.001), diuretic use (p< 0.021) and left ventricular ejection fraction (p< 0.015). Three predictors were identified using regression analyses with stepwise methods, and included age, type of referral and educational level. Conclusion: The very high percentage of patients with poor sleep quality indicates the severity of sleep disturbance in heart failure patients in Vietnam. There are many factors associated with sleep quality and sleep disturbances that doctors, nurses and health authorities need to be aware of in order to improve and manage them effectively.
