Clinical Trials

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.

Have you been diagnosed with peripartum cardiomyopathy and are within 5 months of your due date? This study is evaluating the effectiveness of a medicine called bromocriptine to treat peripartum cardiomyopathy, or weakness of the heart muscle that occurs during or shortly after pregnancy. To participate in this study, you must be at least 18 years old, diagnosed with peripartum cardiomyopathy, and within 5 months of your delivery date. This study takes place in Pittsburgh, Pennsylvania.

Have you recently been diagnosed with Takotsubo Syndrome? This study aims to investigate the short- and long-term effects of takotsubo syndrome, sometimes referred to as broken heart syndrome. Usually, takotsubo syndrome is a temporary heart condition that is caused by either emotional or physical stress. To participate in this study, you must have a new diagnosis of takotsubo syndrome and be at least 18 years old. This study takes place in Providence, Rhode Island.

Do you have cardiomyopathy that has led to moderate or severe mitral regurgitation? This study is exploring the best surgical technique to repair mitral regurgitation by comparing two procedures called undersizing mitral annuloplasty (UMA) and papillary muscle approximation (PMA). A UMA is a common procedure that involves implanting a prosthetic ring onto the mitral valve to stop the valve from leaking. A PMA is a newer technique in which a suture draws together the two muscles that connect the mitral valve to the heart muscle prior to performing UMA. To participate in this study, you must be 18 years old or older and have never had a mitral valve repair procedure. This study takes place in Atlanta, Georgia.

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.

The goal of this research is to assess the utility of smartphone-based progressive muscle relaxation (PMR) for the treatment of migraine and sleep.

The purpose of this project is to test sleep reactivity as an independent cause of Shift Work Disorder (SWD).

Do you have HIV and insomnia? This study is looking at whether insomnia increases pain and inflammation in people who have HIV. To participate in this study, you must be 18 to 85 years old and either be healthy or diagnosed with HIV, with or without insomnia. This study is located in Birmingham, Alabama.

Have you previously been prescribed opioid medicines? This study will find out whether waking up frequently during the night can affect the way your brain processes certain medicines. To participate in this study, you must be 18 to 48 years old, have a normal sleep cycle, and have previously taken opioid medicines to treat pain. This study is located in Baltimore, Maryland.
