“…The association between OSA and cardiovascular risk factors such as obesity and hypertension has been well documented (12,13). Body-mass index values were observed to increase significantly from simple snoring group to severe OSA group in our study which is in agreement with previous studies (p=0.009).…”

“…While some studies have reported the association between OSA and coronary events, there are limited data regarding the association between OSA and subclinical coronary disease. The mechanism of association between OSA and coronary artery disease may be related to deleterious effects of hypoxia on endothelial functions, hyperadrenergic state and the effects of highly prevalent co-existing risk factors (13). Nocturnal desaturation and reoxygenation episodes observed in these patients have been suggested to result in oxidative stress which facilitates the metabolic cascade associated with increased inflammatory response and development of atherosclerosis (14).…”

“…From the present study, it is not possible to explain the mechanism of improvement in FMD after CPAP. Endothelial dysfunction in OSA is believed to be initiated mainly by hypoxia, inflammation, or oxidative stress (21). Not only reduction in vasodilator substances, but also elevated vasoconstrictor substances in OSA play role in the development of endothelial dysfunction.…”

“…Obstructive sleep apnea (OSA) is the most common sleeprelated breathing disorder and is characterized by repetitive narrowing or collapse of the pharyngeal airway during sleep with decreases in oxygen saturation leading to a series of pathological events, primarily in the cardiovascular system (1)(2)(3)(4). The mechanisms by which OSA affects the cardiovascular system may involve mechanical effects on intrathoracic pressure, sympathetic overstimulation, intermittent hypoxia, oxidative stress, inflammation, hyper coagulation, metabolic dysregulation and endothelial dysfunction (3,5).…”

“…The mechanisms by which OSA affects the cardiovascular system may involve mechanical effects on intrathoracic pressure, sympathetic overstimulation, intermittent hypoxia, oxidative stress, inflammation, hyper coagulation, metabolic dysregulation and endothelial dysfunction (3,5). The repetitive respiratory events cause hypoxia, hypercapnea, arousals, or disrupted sleep singly or in combination (6)(7)(8)(9)(10).…”
