Clinical Trials

Are you a woman with coronary microvascular dysfunction? In this clinical trial, researchers are studying coronary microvascular dysfunction, which occurs when there are problems in the small blood vessels in the heart. It frequently causes chest pain and is more common in women. The researchers want to learn how daily life and mental stress affect the heart. You may be able to participate if you are at least 45 years old, have gone through menopause, and are willing to undergo tests to measure your stress level. The study is taking place at locations in Atlanta, Georgia.

Do you or your child have sickle cell disease? Researchers are testing whether a type of gene therapy will prevent all severe vaso-occlusive pain events in individuals living with sickle cell disease. In this study, stems cells are collected from the patient, modified in a lab, and then the gene-modified cells are given back to the patient. Participants must be between 13 and 40 years old. The study is taking place at sickle cell and transplant centers in California, Georgia, Illinois, Massachusetts, and Wisconsin.

Do you have heart disease? This study is looking to improve the quality of heart CT scans by using new methods to create the images. You may be able to participate in the study if you are 18 years old or older, have heart disease, and have been told by your doctor that you need a CT scan. This study is taking place at the National Institutes of Health Clinical Center in Bethesda, Maryland.

Are you 75 years old or older and interested in participating in a clinical trial where researchers are studying whether statins, which are often used to treat high cholesterol, can help improve heart and brain health. To participate, you cannot have cardiovascular disease or dementia. The study is taking place at locations in Alabama, Arizona, Arkansas, California, Connecticut, Florida, Georgia, Illinois, Indiana, Iowa, Kansas, Kentucky, Louisiana, Maine, Maryland, Massachusetts, Michigan, Minnesota, Mississippi, Missouri, Nebraska, Nevada, New York, North Carolina, Ohio, Pennsylvania, Rhode Island, South Carolina, Tennessee, Texas, Utah, Virginia, West Virginia, Wisconsin, and Puerto Rico.

Do you have a child with hypoplastic left heart syndrome (HLHS)? This study is assessing the safety and efficacy of Lomecel-B™ in treating HLHS. Lomecel-B contains human mesenchymal stem cells (MSCs), special cells in the body that are able to change into other types of cells, such as heart, blood, and muscle cells. Lomecel-B uses MSCs from bone marrow of unrelated young healthy donors. These are called "allogeneic", and do not require donor matching to the patient. To participate in the trial, the child must be less than 1 year old and require stage II palliation for all types of HLHS. This study is in multiple locations. Participants will be randomized to receive either an injection of Lomecel-B in the heart or no injection during their Stage II operation. They will be monitored for safety and one year later, heart function will be measured using cardiac MRI, echocardiogram, blood studies, growth, and scales of quality of life and heart failure.

Are you an adult female with LAM? If so, you may be able to participate in this clinical study where researchers are observing patients who are taking or have taken a certain kind of medication, mammalian target of rapamycin (mTOR), to treat lymphangioleiomyomatosis, also known as LAM. You must be at least 18 years old to take part. The study is taking place at locations in California, Colorado, Florida, Georgia, Illinois, Massachusetts, Michigan, Minnesota, Missouri, New York, Ohio, Oregon, Pennsylvania, South Carolina, Tennessee, Texas, Utah, and Washington.

This trial will compare time from randomization to failure of treatment or death from any cause of IST versus URD BMT when used as initial therapy to treat Severe Aplastic Anemia.

Are you at least 18 years old and have been told by your doctor that you need a procedure called transcatheter aortic valve replacement? This study will test a new device designed specifically for use during a procedure called transcatheter aortic valve replacement. Researchers want to make transcatheter aortic valve replacement safer. To be in the study, you must be at least 18 and need a transcatheter aortic valve replacement. The study will take place in locations in California, Georgia, Massachusetts, New York, Virginia, Washington, and Washington, D.C.

Are you an adult with atrial fibrillation? In this study, researchers are comparing a continuous direct oral anticoagulation (DOAC) use versus time-limited (1 month) DOAC guided by an AF-sensing Smart Watch (AFSW) for persons with atrial fibrillation and a moderate risk of stroke. Participants must be between the ages of 22 and 85 and have a history of atrial fibrillation. The study is taking place at locations in California, Colorado, Florida, Georgia, Illinois, Indiana, Iowa, Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, New Jersey, New Mexico, New York, North Carolina, Ohio, Oklahoma, Pennsylvania, South Carolina, Texas, Virginia, Wisconsin, and Washington, D.C.

Do you have mitral valve disease? This clinical trial is testing different types of images taken of the heart to learn more about mitral valve disease and the best ways to treat it. You must be 60 years old to participate. The study is enrolling patients in locations in Arkansas, California, Georgia, Indiana, Louisiana, Maine, Maryland, Massachusetts, Michigan, Missouri, New York, North Carolina, Ohio, Pennsylvania, and Quebec City, Canada.
