阻塞性睡眠呼吸暂停低通气综合征(OSAHS)是一种在睡眠中反复发作的以上气道完全或局部塌陷为特征的疾病,该病通过引起呼吸暂停和(或)低通气,进而出现间歇性低氧和二氧化碳水平升高,并导致频繁的睡眠中断。大量研究证实,心血管疾病发病率和病死率的增加与OSAHS相关,这种关联在糖尿病、高血压、吸烟和血脂异常得以控制后仍然持续存在[1]。动脉粥样硬化是心血管疾病病理生理过程中一个重要 Obstructive sleep apnea-hypopnea syndrome (OSAHS) is a recurrent episode of airway collapse characterized by complete or partial collapse of the airway by causing apnea and / or hypopnea which in turn leads to intermittent Hypoxia and carbon dioxide levels rise, leading to frequent sleep disruptions. Numerous studies have confirmed that increased cardiovascular morbidity and mortality are associated with OSAHS and persist after diabetes, hypertension, smoking, and dyslipidemia are controlled.
