Clinical Trials

Are you an adult who does not have high blood pressure and is interested in research? This study will investigate how the brain regulates the body’s response to stress and how infection with HIV or pre-hypertension affects regulation. Your heart and brain activity will be measured while you are at rest, during a mentally stressful task, and while you feel angry. The study will also test whether a breathing exercise improves regulation. People with and without HIV and pre-hypertension will be included. To participate in this study, you must be between 21 and 65 years old and not have high blood pressure. This study is located in Miami, Florida.

This research study is being done to determine whether the repetition and resistance from the daily use of the myofunctional therapy (MT) nozzle will improve obstructive sleep apnea and primary snoring.

Are you a Minnesota resident with hypertrophic cardiomyopathy? This study aims to find out how common it is for people with hypertrophic cardiomyopathy to also have sleep apnea. Hypertrophic cardiomyopathy is a disease that causes the heart muscle to thicken. Participants will also wear a heart rhythm monitor to help researchers learn whether sleep apnea is linked to arrhythmia. The study seeks healthy volunteers as well as participants in the Hypertrophic Cardiomyopathy Registry. To participate in this study, you must not have had a catheter ablation procedure to treat atrial fibrillation, had surgery to replace your heart valves, or been treated for sleep apnea. The study is located in Rochester, Minnesota.
