Obstructive sleep apnea and aging of the cardiovascular system: a multidimensional analysis of the mechanisms involved

Emerging evidence has revealed a strong association between obstructive sleep apnea (OSA) and aging. Considering the critical role of the cardiovascular system, this review explores the key mechanisms linking OSA to cardiovascular aging through a focus on chronic intermittent hypoxia (CIH) -induced oxidative stress and chronic inflammation. Specifically, we examine six key pathways: (1) cellular senescence, (2) mitochondrial dysfunction, (3) metabolic dysregulation, (4) telomere attrition, (5) impaired intercellular communication, and (6) adipose tissue senescence. These insights provide a foundation for identifying novel interventions and therapeutic targets to mitigate or even reverse cardiovascular aging.
