Continuous Positive Airway Pressure (CPAP) therapy effectively improves daytime sleepiness and quality of life in Obstructive Sleep Apnoea (OSA) patients, but its impact on cardiometabolic outcomes is uncertain and secondary prevention trials have failed to demonstrate significant modification of cardiovascular events.
CPAP is the most effective treatment for stopping snoring and fixing daytime sleepiness in OSA patients. However, do not expect it to automatically fix your heart health or blood sugar levels, as evidence for those benefits is weak. If you struggle with the mask, talk to your doctor about alternatives like oral appliances or nerve stimulation, as adherence is a major hurdle.
Although CPAP is highly effective in improving daytime sleepiness, quality of life, and other symptoms, its effect on cardiometabolic complications is uncertain. ... secondary prevention trials have failed to demonstrate a significant modifying effect on CV outcomes
Why this rating
Based on multiple RCTs and large real-world studies cited, though the paper highlights methodological limitations in CV trials.

- Intermittent Hypoxia (IH) is a key pathogenic factor in OSA that drives cardiovascular and metabolic disease through vascular remodelling, atherosclerosis, and insulin resistance, independent of obesity.Good
- Weight loss, particularly through GLP-1 based pharmacotherapy (e.g., Tirzepatide), significantly reduces OSA severity and improves cardiometabolic markers like blood pressure, offering a promising alternative or adjunct to CPAP.Moderate
