Sleep apnea is associated with reduced daytime blood pressure variability in adults with Down syndrome.

ABSTRACT: Sleep apnea (SA) is common in Down syndrome (DS), but its impact on daytime autonomic control is poorly described. The aim of this study was to assess the impact of SA on autonomic control of heart rate (HR) and blood pressure (BP) during a Head-Up Tilt test (HUTT) in adults with DS. Ancillary cross-sectional analysis of an observational study conducted on 28 adults with DS (31.7 ± 7.4 years; 32% female) free from congenital cardiopathy, thyroid disorders, or medication that impact autonomic control were included. Full-night polysomnography and HUTT were performed. Temporal and spectral analyses were performed on the signals of RR intervals, systolic and diastolic blood pressures (SBP and DBP). SBP and DBP min-max variations were specifically analyzed during the initial 3 min post-tilting
