核心结论：OSA 显著增加心脑血管疾病风险
Core Finding: OSA Significantly Increases Cardiovascular Risk
打鼾 10 年不干预，
心脑血管事件风险为常人的 3-4 倍
Untreated snoring for 10 years,
cardiovascular/cerebrovascular risk is 3-4× that of normal population

慢性间歇性缺氧
Chronic Intermittent Hypoxia
每次呼吸暂停导致血氧饱和度骤降，反复缺氧再氧合，产生大量氧化应激，损伤血管内皮细胞。
Each apnea event causes a sharp drop in blood oxygen saturation. Repeated hypoxia-reoxygenation cycles generate oxidative stress, damaging vascular endothelial cells.
睡眠结构破碎
Fragmented Sleep Architecture
频繁的微觉醒打断深睡眠和 REM 睡眠，导致身体无法完成正常的修复和代谢调节。
Frequent micro-arousals interrupt deep sleep and REM sleep, preventing normal bodily repair and metabolic regulation.
交感神经持续兴奋
Chronic Sympathetic Activation
长期处于这种"战斗状态"会持续损害心血管系统，是 OSA 患者高血压和心律失常高发的核心机制。
Prolonged "fight-or-flight" state continuously damages the cardiovascular system — this is the core mechanism behind hypertension and arrhythmia in OSA patients.
认知功能下降
Cognitive Decline
注意力、记忆力、执行功能全面下降，工作效率降低，事故风险增加（尤其是驾驶）。
Comprehensive decline in attention, memory, and executive function. Reduced work efficiency, increased accident risk (especially while driving).
