The Prevalence and Clinical Features of Hypertension in Patients With Obstructive Sleep Apnea Hypopnea Syndrome and Related Nursing Strategies

Background: Obstructive sleep apnea hypopnea syndrome (OSAHS) is a common sleep-related breathing disorder. Hypertension is frequently a concomitant disorder in patients with OSAHS. Purpose: This study investigates the prevalence and clinical features of hypertension in patients with OSAHS and explores the related nursing strategies. Methods: Three thousand six hundred seven patients were included in this study. Subjects were divided into four groups that were categorized according to apneaYhypopnea index (AHI) scores as follows: control group (control, n = 354) with AHI G 5, mild OSAHS (mild, n = 658) with 5 e AHI G 15, moderate OSAHS (moderate, n = 753) with 15 e AHI G 30, and severe OSAHS (severe, n = 1842) with AHI Q 30. Blood pressure (BP) values were measured at four time points (daytime, evening, nighttime, and morning). The prevalence of hypertension and BP values in the different groups were compared at four time points. Finally, the nighttime-to-daytimemeanBP (MBP;RN/D) and morning-to-evening MBP (R
