OSA and heart disease

Obstructive Sleep Apnea is strongly associated with many cardiovascular diseases, including myocardial infarction, cardiac arrthymia, stroke and heart failure. Below, David discusses the development of cardiovascular disease in OSA.

The hypoxaemia associated with Sleep Disordered Breathing will exacerbate myocardial ischaemia, and patients with sleep disordered breathing will develop nocturnal angina. Similarly, there is greater prevalence of OSA in persons with Congestive Heart Failure. Repeated desaturations associated with OSA may also worsen heart function (causing both systolic and diastolic cardiac dysfunction).
