Sleep disorders are fairly common among patients with chronic heart failure (HF), and significantly
impacts their life. The purpose of the study was to assess the sleep quality using the Pittsburgh Sleep Quality Index (PSQI) in patients with HF.
This cross-sectional study was conducted on a sample of 280 patients with HF visiting a tertiary care center. Patients filled a demographic questionnaire and their sleep quality was assessed using PSQI. Descriptive statistics were used for qualitative variables. Mean and standard deviation was used for quantitative variables. T-test, Chi-square, and Pearson’s correlation was also used.
Eighty-eight percent of the patients had a PSQI score of greater than 5 points and were identified as having poor sleep quality. The range of global PSQI scores was 4 to 16 points. There was a significant relationship between PSQI scores with smoking (p=0.000), diabetes (p=0.003), and EF (p=0.000). More than half of the patients suffered from day time dysfunction. About one-third of the patients used sleep medications.
A high prevalence of poor sleep quality shows the importance of sleep quality in HF patients. These factors should be recognized and addressed by the health providers.
