The Effects of Obstructive Sleep Apnea on Blood Pressure Measurement Clinical Trial
Official title:
The Changes in Blood Pressure in Patients With Obstructive Sleep Apnea Following an Overnight Sleep
Bidirectional and causal relationship exists between obstructive sleep apnea (OSA) and hypertension in a dose-response manner, independent of confounding variables such as age, smoking, and body mass index. OSA is conventionally diagnosed and graded by apnea-hypopnea index (AHI). The relationship between AHI and changes of blood pressure deserves further investigation.
Approximately 50% of patients with obstructive sleep apnea (OSA) have hypertension; up to 30% of patients with hypertension have OSA, and the prevalence is even higher in those of resistant hypertension. OSA is conventionally diagnosed and graded by apnea-hypopnea index (AHI). This retrospective study aimed to determine if OSA severity and AHI have effect on blood pressure measurements and the nocturnal changes following an overnight sleep. ;
