ClinConnect Summary
This clinical trial is studying how a treatment called CPAP (Continuous Positive Airway Pressure) affects blood pressure in patients who have sleep apnea but are not currently experiencing high blood pressure. The main goal is to see if using CPAP helps lower blood pressure in people who have a specific sleeping pattern known as a "dipper circadian pattern." Additionally, the researchers want to understand how often different blood pressure patterns occur, how well patients stick to using the CPAP, and what changes happen in certain blood markers during treatment.
To participate in this study, you need to be an adult over 18 years old, referred for suspected sleep apnea, and have a specific level of severity in your sleep study. You'll be randomly assigned to either receive CPAP treatment or a different kind of care. Participants will undergo blood pressure monitoring and provide blood samples at the start of the study and again after three months. This trial is currently recruiting participants, and it's important to note that those with certain health conditions or previous CPAP use are not eligible. If you’re interested or think you might qualify, talk to your healthcare provider for more information.
