Clinical Trials

Did you develop atrial fibrillation after coronary artery bypass graft (CABG) surgery? Did you develop atrial fibrillation after a coronary artery bypass grafting (CABG) surgery? This study is looking at how well oral anticoagulation medicines work to prevent complications, such as blood clots and heart attack, for patients who experience post-operative atrial fibrillation (POAF). This study is in multiple locations around the country.

Are you an adult with sickle cell disease? This study aims to determine whether monthly exchange blood transfusions (removing blood and replacing it with transfused red blood cells) can improve health and prevent or reduce the number of pain crises. To participate in this study, you must be at least 18 years old, have sickle cell disease, and have not been on a chronic exchange transfusion program for at least 2 months. This study is located in Pittsburgh, Pennsylvania.

Do you or your child have Williams Syndrome (WS) or supravalvular aortic stenosis (SVAS) or are you interested in helping research on these conditions? The blood vessels in people with WS or SVAS have less elasticity, which can cause them to narrow. This study aims to see how blood vessel differences in people with these conditions affect organs in the body including the heart, gut, kidneys, and brain. This study is open to people with one of these conditions or healthy volunteers between 3 and 85 years old. The study takes place at the NIH Clinical Center in Bethesda,

Do you or your child have Williams-Beuren syndrome (WS) or Supravalvular Aortic Stenosis (SVAS)? Symptoms of both conditions include vascular problems that can be mild or serious. Researchers want to find out why only some people with WS and SVAS have serious symptoms while others do not. Participants in this study will provide blood or saliva samples to help researchers see what DNA or environmental changes affect the severity of the disease. This study is located at the NIH Clinical Center in Bethesda, Maryland.

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.

Are you 65 years old or older, and do you have severe primary mitral regurgitation? This condition — also called degenerative mitral regurgitation — happens when there is a problem with the mitral valve itself or its supporting tissue, leading to a leaky valve. This study is comparing the safety and effectiveness of two different ways of repairing the mitral valve: transcatheter edge-to-edge repair and surgical repair. To participate in this study, your healthcare provider must determine that you are a candidate for both mitral valve transcatheter edge-to-edge repair and surgical repair. This study takes place in multiple locations across the United States and Canada.

Do you or your child have severe asthma that is not easily controlled by inhaled corticosteroids? This study evaluates the use of five different asthma medicines to treat adults and adolescents with severe asthma. To participate in this study, you or your child must be 12 years old or older. This study takes place in multiple locations across the United States.

This study evaluates a sensor-controlled digital game (SCDG) to motivate self-management behaviors of weight monitoring and physical activity in adults with heart failure (HF). Half of the participants will receive the SCDG app and weight monitoring and physical activity sensors and the other half will receive only the weight monitoring and physical activity sensors.

This observational trial studies whether respiratory viruses are the cause of lung disease (bronchiolitis obliterans syndrome [BOS] or graft-versus-host disease of the lung) and changes in lung function in patients who have received a donor stem cell transplant. Patients with chronic graft-versus-host disease (cGVHD) are at higher risk of developing BOS. Studies have also shown that patients who had a respiratory viral illness early after their transplant are at higher risk of developing lung problems later on. Patients who are at risk and who already have BOS might benefit from being monitored more closely. Spirometry is a way of assessing a patient's lung function and is often used to diagnose lung disease. Spirometry measured at home with a simple handheld device may reduce the burden of performing pulmonary function testing at a facility and potentially help patients get their lung disease diagnosed and treated sooner.

This study assesses cardiovascular injury and cardiac fitness in patients with non-small cell lung cancer that has spread to nearby tissue or lymph nodes (locally advanced) receiving model based personalized chemoradiation. The goal of this study is to learn more about the risk of developing heart disease as a result of chemoradiation treatment for lung cancer. Researchers also want to learn if the risk can be reduced by using a patient's individual risk profile to guide cancer treatment and help protect the heart.
