Large prospective studies have established that OSA is associated with an increased incidence of hypertension and especially of coronary disease, stroke, pulmonary vascular disease, ischemic heart disease, cerebral vascular accidents, congestive heart failure, and arrhythmias.


Cardiovascular diseases

Obstructive sleep apnea is associated with obesity, which is also a major risk factor for heart disease and stroke. Besides obesity contributing to sleep apnea, sleep deprivation caused by sleep apnea can, in an ongoing unhealthy cycle, lead to further obesity.

Cardiac arrhythmias, especially tachy-brady syndrome, ventricular ectopy, and atrial fibrillation are commonly identified in patients with OSA.
