Clinical Trials

Are you in need of a heart or lung transplant or have you had one in the past 3 months? Have you undergone a lung or heart transplant in the past 3 months or are you a candidate for heart or lung transplant? Some people with advanced heart and lung disease have heart and lung transplants but these new organs are often rejected. When this happens, patients must have repeated biopsies, which are invasive and expensive. Researchers in this clinical study want to see if a blood test can predict organ rejection and take the place of biopsies. To participate, you must be 18 to 80 years old and be a candidate for heart or lung transplant or have had a heart or lung transplant no more than three months ago. The study is taking place in Bethesda, Maryland, at the NIH Clinical Center, as well as in Baltimore, Maryland, and Falls Church, Virginia.

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.
