Correlation among obstructive sleep apnea syndrome, coronary atherosclerosis and coronary heart disease.

is as high as 30%−50%. 1 Many studies have indicated that OSAS may be closely associated with the development of CAD since increased incidence and mortality of CAD were found in OSAS patients. However, although it has been confirmed that OSAS is an independent risk factor for hypertension, its exact correlation with CAD has not been entirely elucidated. The aim of the present study was to explore the correlation between the degrees of OSAS and CAD with the application of coronary artery angiography (CAA), Gensini scoring evaluation system, and other risk factors which may contribute to CAD.
