Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Sleep-disordered breathing including obstructive sleep apnea (OSA) is an extremely common medical disorder associated with important morbidity. The purpose of this study is to understand the clinical features and course of patients with sleep apnea in Korea. Participants who are suspected of sleep apnea due to symptoms such as snoring, witnessed apneas, waking up with a choking sensation, excessive sleepiness, non-restorative sleep, difficulty initiating or maintaining sleep, fatigue or tiredness, and morning headache will be prospectively recruited at the outpatient clinic of Seoul National University Hospital. After polysomnography (PSG) or respiratory polygraphy, patients with sleep apnea including OSA and central sleep apnea (CSA) will be followed regularly. Participants not having sleep apnea (apnea-hypopnea index \< 5/hour) will only have a baseline visit. For only participants with the informed consent of donating blood, their blood samples will be collected and stored in the Seoul National University Hospital-Human Biobank (SNUH-HUB).

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

obstructive sleep apnea (OSA)

5 or more predominantly obstructive respiratory events \[obstructive and mixed apneas, hypopneas or respiratory effort-related arousals (RERAs)\] per hour of sleep during a PSG or per hour of monitoring (respiratory polygraphy)

No interventions assigned to this group

central sleep apnea (CSA)

PSG shows all of the following:

1. 5 or more central apneas and/or central hypopneas per hour of sleep.
2. The number of central and/or central hypopneas is \> 50% of the total number of apneas and hypopneas.

No interventions assigned to this group

control

apnea-hypopnea index \< 5 per hour of sleep during a PSG or per hour of monitoring (respiratory polygraphy)

No interventions assigned to this group
