阻塞性睡眠呼吸暂停(OSA)在2%的中年女性和4%的中年男性中发生,在肥胖者中发病率较高。这种情况被认为是脑血管和心血管疾病的独立危险因素。间歇性低氧是阻塞性睡眠呼吸暂停综合征的主要病理生理特征之一。低氧可导致氧化应激和活性氧的过量产生,这可能导致内皮功能障碍,这是动脉粥样硬化的一个标志。许多动物模型,如间歇性低氧的啮齿动物模型,模拟了人类患者的阻塞性睡眠呼吸暂停,并允许更深入地研究这种情况的生物学和细胞机制。该综述讨论了氧化应激在阻塞性睡眠呼吸暂停综合征引起的人类和动物模型心血管疾病中的作用。
Obstructive sleep apnea (OSA) occurs in 2% of middle-aged women and 4% of middle-aged men with a higher prevalence among obese subjects. This condition is considered as an independent risk factor for cerebrovascular and cardiovascular diseases. One of the major pathophysiological characteristics of OSA is intermittent hypoxia. Hypoxia can lead to oxidative stress and overproduction of reactive oxygen species, which can lead to endothelial dysfunction, a hallmark of atherosclerosis. Many animal models, such as the rodent model of intermittent hypoxia, mimic obstructive sleep apnea in human patients and allow more in-depth investigation of biological and cellular mechanisms of this condition. This review discusses the role of oxidative stress in cardiovascular disease resulting from OSA in humans and animal models.
