Sleep related breathing disorders comprises disorders related abnormal pattern and status of the gas exchange during sleep. It has been reported that abnormal sleep pattern could results in an autonomic dysfunction during sleep and ends up to increase possibility to induce stroke and cardiovascular disease associated with atherosclerosis. Stroke is a disorder, which could cause death and critical disability in the adulthood. Sleep related breathing disorders and stroke has causal relationship in each other, which could influence on recovery to each other. Systematic evaluation and management for sleep disorder after stroke might have clinical importance. This review will comprise of topics about sleep related disorders in stroke patients including epidemiology, relationship between stroke and sleep disorder, diagnosis, and management of frequent sleep disorder.

OBJECTIVE: To assess the frequency and severity of sleep-disordered breathing (SDB) in subacute stroke patients in Korea. METHODS: We consecutively enrolled subacute stroke patients who were transferred to the Department of Rehabilitation Medicine from February 2016 to August 2016. The inclusion criteria were as follows: diagnosis of the first onset of cerebral infarction or hemorrhage in the brain by computed tomography or magnetic resonance imaging; patients between 18 and 80 years old; and patients admitted within 7 days to 6 months after stroke onset. We evaluated baseline clinical data on patients' admission to the Department of Rehabilitation Medicine. We assessed demographic data, stroke severity, neurologic impairment, cognition and quality of life. We used the Epworth Sleepiness Scale to assess quality of sleep. We used a portable polysomnography to detect SDB. RESULTS: Of the 194 stroke patients, 76 patients enrolled in this study. We evaluated and included 46 patients in the outcome analysis. The mean apnea-hypopnea index (AHI) was 24.2±17.0 and 31 patients (67.4%) exhibited an AHI ≥15. Those in the SDB group showed a higher National Institutes of Health Stroke Scale, lower Functional Ambulation Category, lower Korean version of Modified Barthel Index, and lower EuroQol five dimensions questionnaire (EQ-5D) at admission. Prevalence and clinical characteristics of SDB did not show significant differences among stroke types or locations. CONCLUSION: SDB is common in subacute stroke patients. SDB must be evaluated after a stroke, particularly in patients presenting severe neurologic impairment.

OBJECTIVE: To evaluate the level of health-related quality of life (HRQoL), life satisfaction, and their present awareness of cardiac rehabilitation (CR) program in people with cardiovascular diseases. METHODS: A questionnaire survey was completed by 53 patients (mean age, 65.7±11.6 years; 33 men and 20 women) with unstable angina, myocardial infarction, or heart failure. The questionnaire included the Medical Outcome Study 36-item Short-Form Health Survey (MOS SF-36), life domain satisfaction measure (LDSM), and the awareness and degree of using CR program. RESULTS: The average scores of physical component summary (PCS) and mental component summary (MCS) were 47.7±18.5 and 56.5±19.5, respectively. There were significant differences in physical role (F=4.2, p=0.02), vitality (F=10.7, p<0.001), mental health (F=15.9, p<0.001), PCS (F=3.6, p=0.034), and MCS (F=11.9, p<0.001) between disease types. The average LDSM score was 4.7±1.5. Age and disease duration were negatively correlated with multiple HRQoL areas (p<0.05). Monthly income, ejection fraction, and LDSM were positively correlated with several MOS SF-36 factors (p<0.05). However, the number of modifiable risk factors had no significant correlation with medication. Thirty-seven subjects (69.8%) answered that they had not previously heard about CR program. Seventeen patients (32.1%) reported that they were actively participating in CR program. Most people said that a reasonable cost of CR was less than 100,000 Korean won per month. CONCLUSION: CR should focus on improving the physical components of quality of life. In addition, physicians should actively promote CR to cardiovascular disease patients to expand the reach of CR program.
