"CPAP for OSA improves quality of life but does not reduce CVD events"
There is often pressure to get help for patients with obstructive sleep apnoea (OSA) in case they have a cardiovascular event.
An ABC Radio Health Report podcast refers to a trial where Prof Ron Grunstein, an investigator, explained that the patients studied were primarily men who had moderate-to-severe OSA and coronary or cerebrovascular disease. They received continuous positive airway pressure (CPAP) treatment plus usual care (CPAP group) or usual care alone (usual care group).1 There were 3246 participants in the study.2 There were no differences in terms of CVD outcomes. However the CPAP group had better Epworth sleepiness scores, depression, anxiety and quality of life scores.
The take home message is that patients do better in terms of subjective measures of living but with no gain in terms of CVD events.
