Are you scheduled for a stem cell transplant with cord blood? This study will assess the safety and effectiveness of certain cord blood transplants. The study will help researchers learn the best methods for collecting, storing, and using cord blood in transplants. To participate in this study, you must have a disorder that compromises your body’s ability to make blood cells. This study is located in Bethesda, Maryland.

Do you or your child have a disease affecting the blood vessels? This study is collecting blood samples to study the role of inflammation in diseases of the blood vessels, including coronary heart disease and sickle cell disease. To participate, you or your child must be at least 2 years old and either be healthy or have a disease affecting the blood vessels. This study is located in Bethesda, Maryland.

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 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.

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.

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.
