Clinical Trials

Este estudio explora si un medicamento llamado espironolactona puede mejorar la función cardíaca y pulmonar durante el ejercicio en personas con hipertensión pulmonar. Para participar en este estudio, debe tener entre 18 y 99 años y un tipo de hipertensión pulmonar conocido como hipertensión arterial pulmonar. Este estudio se lleva a cabo en Bethesda (Maryland).

Do you have metabolic syndrome? This trial is testing whether low-intensity exercise or high-intensity exercise works best to lower the risk of heart and blood vessel diseases in people who have metabolic syndrome and are taking a medicine called metformin to treat high blood sugar levels. To participate in this study, you must be between 40 and 80 years old and diagnosed with metabolic syndrome but not type 2 diabetes. This study takes place in New Brunswick, New Jersey.

Do you or your child have overweight or obesity? This study aims to find effective ways to prevent and treat obesity and metabolic syndrome in African American communities. The study will test the effectiveness of a family-based comprehensive health and fitness programs involving community health workers. Participants must be 12 years old or older and African American and have overweight or obesity. This study takes place in Charleston, South Carolina.

Do you have low blood pressure due to primary autonomic failure from a medical condition such as Parkinson disease, multiple system atrophy, or pure autonomic failure? Autonomic failure is caused by problems with a part of the nervous system called the autonomic nervous system. People with this condition can suffer debilitating low blood pressure upon standing. This study is testing the use of compression garments compared with a medicine called midodrine to improve blood pressure. To participate in this study, you must be between 18 and 80 years old and have low blood pressure when standing. This study takes place in Nashville, Tennessee.

Do you have cerebral autosomal dominant arteriopathy with subcortical infarct and leukoencephalopathy (CADASIL) or want to help someone with the condition? This study aims to learn more about a rare genetic disease called CADASIL. This condition causes small blood vessels in the body to become narrow, which can block blood flow to the brain and lead to a stroke. The study includes blood, urine, and imaging tests. This study is located at the NIH Clinical Center in Bethesda, Maryland.

Do you or your child have bone marrow failure disease or a telomere biology disorder? This study looks at the long-term effects of bone marrow failure disease and its treatments on organ function. Participants in this study must be 2 years or older with bone marrow failure or telomere biology disorder. This study is located at the NIH Clinical Center in Bethesda, Maryland.

Are you able to have a magnetic resonance imaging (MRI) scan and want to help people with heart failure? This study is developing new methods for imaging the heart and blood vessels using MRI to improve how healthcare providers diagnose people with heart failure. This study takes place in Maryland and Washington, DC.

Are you a male with psoriasis or want to help someone with this condition? This study is exploring whether eating only during certain hours of the day (called time-restricted feeding) can change metabolism and reduce inflammation in the blood of people with mild to moderate psoriasis. To participate in this study, you must be a male between the ages of 18 and 80 with active psoriasis, or be a healthy volunteer. This study is located at the NIH Clinical Center in Bethesda, Maryland.

Have you had a genetic test that revealed a change (mutation) in the genes that affect your body's elastic fibers? This study aims to learn more about the impact of changes in connective tissue genes on an individual's overall health. To participate in this study, you or your child must be between the ages of 2 and 100 years old. You must have also had a genetic test that identified changes in a gene that affects elastic fibers (e.g., ELN, LOX, MFAP4, FBLN5 and EFEMP). This study is located at the NIH Clinical Center in Bethesda, Maryland.

Do you or your child have severe aplastic anemia? This study tests the safety and effectiveness of two medicines called cyclosporine and eltrombopag in people with severe aplastic anemia. The typical treatment is a combination of three medicines: cyclosporine, eltrombopag, and horse anti-thymocyte globulin. Researchers want to see if starting people at a lower dose of cyclosporine and eltrombopag before giving them horse anti-thymocyte globulin is helpful. Participants in this study must be 4 years or older with severe aplastic anemia. This study is located at the NIH Clinical Center in Bethesda, Maryland.
