Risk factors for OSA include obesity, increasing age, being male, abnormal craniofacial morphology, nasal obstruction, genetic factors. OSA is associated with several cardiovascular consequences and social consequences e.g. motor vehicle accidents, impaired cognitive performance, depression. Various epidemiologic studies have shown an association between OSA and hypertension. In cross-sectional study, OSA was associated with increased prevalence of self-reported heart failure and stroke. OSA has been shown to be independently associated with coronary artery disease after adjustment for traditionally considered risk factors.
