Brief summary
This study aims to investigate the effects of cardiac rehabilitation on sleep quality and sleep duration in patients after coronary artery bypass graft.
Detailed description
Coronary artery disease (CAD) is one of the common cardiovascular diseases, including myocardial infarction and unstable angina pectoris. Using the Global Burden of Disease statistical data analysis in 2020, Khan and other scholars found that the global prevalence of CAD is about 1,655 per 100,000 people, and the prevalence rate in Taiwan is about 1759 per 100,000 people, slightly higher than the global prevalence rate. Therefore, all countries in the world attach great importance to the prevention and treatment of CAD. In addition to common risk factors such as age, metabolic disease, smoking, and poor lifestyle habits such as insufficient physical activity, the literature indicates that sleep quality and sleep duration are also significantly associated with CAD. A 2011 meta-analysis by Francesco et al. pointed out that people who sleep less than 5 hours have a higher risk of CAD and are significantly associated with higher mortality rate. Patients with CAD who self-reported poor sleep quality and short sleep duration still had a high proportion after heart-related treatment. In 1993, Redeker tracked the related symptoms of patients after coronary artery bypass graft(CABG) and found that the sleep disturbance of patients did not improve, but increased. A systematic review of the literature by Liao et al. also found similar results. The sleep quality and sleep duration of patients after CABG can be improved over time, but a high proportion of patients still complain of sleep disturbance. Therefore, the influence of sleep disturbance in patients with CAD will persist, and studies have also suggested that persistent sleep disturbance will increase the readmission rate and mortality rate of patients with CAD. Therefore, it is very important to actively manage the sleep quality and sleep time of patients with CAD.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Pittsburgh Sleep Quality Index (PSQI) | Change between baseline and 3 mons. after cardiac rehabilitation | Range of 0-21, higher scores indicate worse sleep quality. Scores \> 5 are taken to represent poor sleep quality |
| Actigraphy | Change between baseline and 3 mons. after cardiac rehabilitation | Objective sleep parameter. Wear on the non-dominant wrist for 24 hrs. Can measure the total sleep time (TST), sleep onset latency (SOL), wake after sleep onset (WASO), sleep efficiency (SE) |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Epworth Sleepiness Scale (ESS) | Change between baseline and 3 mons. after cardiac rehabilitation | General level of daytime sleepiness . 8 self-rated questions. The chance of dozing is rated on a scale of 0-3. Range of 0-24, higher scores indicate worse daytime sleepiness. Scores \> 10 are taken to represent excessive daytime sleepiness. |
| Visual analogue scale | Change between baseline and 3 mons. after cardiac rehabilitation | Pain rating scales. Mark a 100 mm line to indicate pain intensity. 0 mm = no pain, 100 mm = worst pain |
| Hospital Anxiety and Depression Scale (HADS) | Change between baseline and 3 mons. after cardiac rehabilitation | Range of 0-21, higher scores indicate worse anxiety or depression. Scores \> 10 are taken to represent anxiety or depression |
| Cardiopulmonary exercise testing (CPET) | Change between baseline and 3 mons. after cardiac rehabilitation | Gold standard for exercise capacity. Protocol: Starting form 0 watt, increase 10-15 watt/min. Test termination: Reach ≥ 85% of maximal HR, Respiratory exchange ratio (RER) \> 1.10, Participants feel exhausted |
