Sleep quality among different classes of heart failure patients in Jordan: A STROBE compliant cross-sectional study.

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.
