Clinical Trial: Assessment of Heart Rate Variability for Predicting Obstructive Sleep Apnea in Patients With Hypertension

U.S., May 23 -- ClinicalTrials.gov registry received information related to the study (NCT07603583) titled 'Assessment of Heart Rate Variability for Predicting Obstructive Sleep Apnea in Patients With Hypertension' on May 18.

Brief Summary: This study aims to investigate the relationship between hypertension and obstructive sleep apnea (OSA) using heart rate variability (HRV) as a non-invasive biomarker of autonomic nervous system function.

Hypertensive patients at high risk for OSA will undergo 24-hour Holter electrocardiogram monitoring to assess HRV parameters, along with overnight polysomnography (PSG) to determine OSA severity. The study will analyze the association between HRV indices and the apnea-hypopnea index (AHI), and develop ...
