What this trial studies

This observational study aims to gather clinical data on patients with sleep apnea syndromes in Korea. Participants suspected of having sleep apnea will be recruited based on specific symptoms and will undergo polysomnography or respiratory polygraphy for diagnosis. Those diagnosed with sleep apnea will be followed regularly, while those without the condition will only have a baseline visit. Blood samples will be collected from participants who consent to contribute to further research.
