Sleep apnea may explain non-dipping and elevate CV risk; leaves open whether treatment improves outcomes.
Sleep apnea contributes to non-dipping nocturnal blood pressure via hypoxia and increased preload, with daytime BP potentially responding to beta-blockers and nocturnal BP showing only slight response to CPAP.
Michael G. Ziegler (2003) conducted a review in Sleep apnea and non-dipping blood pressure. Sleep apnea was evaluated. Sleep apnea increases nighttime blood pressure through enhanced cardiac pre-load, sleep disturbance, and hypoxia, and responds only slightly to continuous positive airway pressure therapy.
