Many researchers emphasize the importance of studying sleep quality among patients with heart failure (HF). Because of the importance of this topic, many studies have been conducted to address the different aspects of sleep-in various populations of patients with HF. The purposes of our study were: to assess the types of disturbances in sleep within the different classes of HF, and to assess whether there were differences in the levels of sleep quality and types of disturbances in sleep within the different classes in non-hospitalized Jordan patients with HF. Data were gathered from 2 cardiac clinics and 2 medical clinics at 3 Jordan hospitals. A minimum sample of 200 people was recruited to participate in this study based on these criteria and factors. The prevalence of low sleep quality and types of disturbances in sleep were increased with the increase in New York Heart Association class. Nearly 3 quarters of the study sample had poor sleep quality 73.5% (n = 147). Using a score of 5 as a cut point, 147 patients with HF in our study sample had poor sleep quality. The most common types in all classes were waking up for urination, waking in the middle of the night or early morning, waking up due to coughing and snoring, and difficulty falling asleep within 30 minutes. However, waking up due to feeling cold or hot were rarely reported in all classes of patients with HF. Poor sleep quality negatively affects the quality of life in patients with HF by decreasing physical cognitive and psychosocial performance in those patients. This is the first study in literature study sleep quality in the different New York Heart Association functional classes.
Awareness of poor sleep quality and sleep disturbances, as some of the factors that affect negatively quality of life for patients with the different classes of heart failure (HF) would enable health care providers to offer more comprehensive care. The purposes of this study were to describe sleep quality and predictors of disturbances in sleep in heart failure patients in Jordan. An explanatory cross- sectional design was employed to examine sleep quality, dimensions of sleep characteristics, types of disturbances in sleep within the different classes of HF in Jordan. Data were collected from 2 cardiac clinics and 2 medical clinics at 3 hospitals in Jordan. The most common types of disturbances in sleep in all classes of HF were waking up for urination, waking in the middle of the night or early morning, waking up due to cough and snoring, and difficulty to fall asleep within the 30 minutes. However, waking up due to feeling cold or hot were rarely reported in all classes of patients with HF. Regression analysis revealed that significant correlations were found between sleep quality and gender, disease duration, number of medications currently taken and ejection fraction ( P < .05). Our findings indicated that sleep quality and disturbances in sleep were worsening with the increase of the New York heart association functional classification sheet class. Moreover, sleep quality had a significant association with gender, disease duration, ejection fraction, and the number of medications currently taken.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
