Prevalence of Obstructive Sleep Apnea in Patients With Peripheral Arterial Occlusive Disease
Recruiting now
Conditions studied: Peripheral Artery Disease
In brief
Obstructive sleep apnea syndrome (OSAS) is characterized by partial (hypopnea) or complete (apnea) obstruction of the upper airways, leading to intermittent hypoxemia and sleep fragmentation. Peripheral arterial occlusive disease (PAOD) is a chronic condition defined by the narrowing or occlusion of arteries in the lower limbs, often resulting in ischemia of downstream tissues. This disease is a common complication of atherosclerosis and affects approximately 1.2% of the general French population. OSAS is a well-established risk factor for atherosclerotic disease, particularly for coronary and neurovascular events. Although a relationship between OSAS and PAOD has been investigated in recent years, the link has not been definitively established and requires further study. Therefore, this preliminary cohort study aims to observe the prevalence of OSAS among patients diagnosed with PAOD, regardless of the disease stage.
