Sleep-Disordered Breathing and Hypertension-A Systematic Review.

Background/

Objectives

Sleep-disordered breathing (SDB), historically referred to as "sleep apnea syndrome", particularly obstructive sleep apnea (OSA), is an independent risk factor for hypertension (HTN), stroke, heart failure, arrhythmias, and other cardiovascular disorders. Despite the well-established link between OSA and HTN and its high occurrence in cardiovascular disorders, the focus on the complex OSA-HTN axis is often overlooked or inadequately managed, which might explain the lack of notable improvements in cardiovascular outcomes for this patient population. Understanding the complex relationship between OSA and HTN is crucial due to its significant implications for clinical practice and public health.

Methods

Using an expanded list of relevant MeSH terms, including "sleep-disordered breathing" and "sleep apnea syndrome", and following the PRISMA model, peer-reviewed articles were systematically selected. Studies published from January 2000 through December 2024 were identified and screened based on predefined inclusion and exclusion criteria.

Results

This review emphasizes both OSA's independent and interaction effects on cardiovascular health and outcomes across different populations. It identifies key factors mediating the association between OSA and HTN.

Conclusions

Multimodal management, including continuous positive airway pressure and lifestyle modification, is essential for treating hypertension related to OSA. Effective management of the OSA-HTN relationship is vital to improving cardiovascular outcomes.
