What is the connection between sleep apnea and PH? Obstructive sleep apnea (OSA) has been identified as a significant cause of and/or contributor to cardiovascular disease. OSA has been shown to increase the risk for hypertension, pulmonary vascular disease, ischemic heart disease, stroke, congestive heart failure, and arrhythmias. The true relationship remains controversial despite the growing body of evidence that links OSA to the development of cardiovascular disease. Many risk factors for OSA are also known risk factors for cardiovascular disease, such as age, male gender, obesity, diabetes mellitus and hypertension. Therefore, it is difficult to prove whether OSA independently...

Obstructive sleep apnea (OSA) is a common and frequently unrecognized disorder. It is often found in patients with obesity, diabetes, and cardiovascular disease, and there is growing evidence that sleep apnea is independently associated with increased cardiovascular morbidity. This article reviews the presentation, diagnosis, and treatment of OSA and its related health risks. It also discusses the proposed associations between OSA and diabetes and insulin resistance. Diabetes and obstructive sleep apnea (OSA) are common disorders that often coexist. One explanation for this overlap is the presence of shared risk factors such as obesity. There may also be a more complex...
