Abstract

Objectives: This study aimed to investigate sleep architecture and sleep-related disorders in hypertensive patients treated at the Department of Respiratory and Cardiovascular Medicine, Hai Phong University of Medicine and Pharmacy Hospital in 2024. Subjects and Methods: A cross-sectional study was conducted on 36 hypertensive patients using overnight polysomnography (PSG) to assess sleep quality, sleep efficiency, sleep stages, apnea–hypopnea index (AHI), oxygen saturation (SpO₂), and movement-related sleep disorders. Results: The study revealed a reduced mean sleep efficiency of 71.11%. A high prevalence of obstructive sleep apnea (OSA) was observed in 77.8% of participants, alongside fragmented sleep (77.8%) and periodic limb movements in sleep (PLMS ≥15/hour) in 33.3%. The mean AHI was 24.23 events/hour, with a mean oxygen saturation nadir of 80.61% and 6.9% of total sleep time spent with SpO₂ below 90%. REM and deep sleep (N3) stages were significantly reduced, with prolonged sleep latency and REM latency. Conclusion: The findings indicate a strong association between hypertension and sleep disturbances, particularly OSA and disrupted sleep architecture. These alterations contribute to intermittent nocturnal hypoxemia and may exacerbate cardiovascular morbidity. Routine PSG screening in hypertensive patients may facilitate early identification and management of comorbid sleep disorders, thereby improving overall cardiovascular outcomes.
