This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
This trial is testing whether using a CPAP machine — a device that helps keep your airway open while you sleep — can protect your heart and blood pressure in people with severe obstructive sleep apnea. You have severe sleep apnea (meaning you stop breathing many times each night) but currently have normal blood pressure, which makes you a unique group to study. Researchers want to see if the CPAP machine can help prevent blood pressure problems from developing in the future.
Most people with severe sleep apnea eventually develop high blood pressure, which increases the risk of heart disease and stroke. This study wants to understand whether treating sleep apnea early with this breathing device can actually prevent these heart problems from starting in the first place.

If you join this study, you will be randomly assigned to either use a CPAP machine nightly for three months or follow healthy lifestyle changes (diet and exercise). You will have three clinic visits: at the start, after one month, and after three months. At the first and final visits, you will wear a blood pressure monitor for 24 hours and have blood tests. Throughout the study, researchers will check how well the treatment is working and how you are doing.
