Clinical Trials and Studies

Are you an adult with postural tachycardia syndrome (POTS)? This study is investigating whether an antibody-mediated autoimmune reaction lead to the dizziness and other symptoms of POTS. The study will also test whether vagal stimulation improves POTS symptoms. This study takes place in Oklahoma City, Oklahoma.

Are you an adult with cardiomyopathy who is eligible for a left ventricular assist device (LVAD)? This study is investigating whether a ventricular arrhythmia (VTA) ablation at the same time that an LVAD is implanted lowers the risk of VTA after surgery. This study is located in Rochester, New York.

Are you at least 12 weeks pregnant? This study is recruiting women with healthy pregnancies and women who have experienced an abnormal fetal heart rate or rhythm. Researchers are evaluating fetal magnetocardiography as a new tool to improve the study of fetal heart rate and rhythm. This study is located in Madison, Wisconsin.

Are you at least 55 years old and fully insured by Blue Cross Blue Shield of Louisiana, and do you want to improve your blood pressure? This study is testing a health coaching approach to help people with high blood pressure take their medicine correctly and on time. To participate in this study, you must have high blood pressure that is not well-controlled by medicine. This study takes place in New Orleans, Louisiana.

Do you have low blood pressure due to primary autonomic failure or multiple system atrophy? Autonomic failure is caused by problems with a part of the nervous system called the autonomic nervous system. People with these conditions can suffer debilitating low blood pressure upon standing. This study is testing the use of compression garments to improve blood pressure in people with these conditions. To participate in this study, you must be between 40 and 80 years old and have low blood pressure when standing. This study takes place in Nashville, Tennessee.

Are you older than 40 and have a history of peripheral artery disease (PAD)? This study will examine whether the drug rivaroxaban improves symptoms associated with peripheral artery disease (PAD). To participate in this study, you must be at least 40 years old and have a history of PAD. This study takes place in Nashville, Tennessee.

Has your child been treated for an asthma attack with an oral corticosteroid medicine in the last 12 months? A study team will recruit 60 teens and young adults (between 12 and 21 years old) with persistent asthma who are at high risk for future exacerbation. This study examines the contribution of interleukin 1 beta (IL-1β), a protein that is involved in the inflammatory response, in asthma flare-ups. This study takes place in Chapel Hill, North Carolina.

Are you an adult with asthma, and do you want to help researchers understand how asthma may affect the brain health? This study is examining whether long-term asthma complications are associated with brain structure, function, or cognitive function. In people with asthma, allergens can induce airway inflammation, which activates several cell types that could negatively affect the brain over time. Results from this study may shed light on whether there is a connection between brain health and asthma. To participate in this study, you must be between 18 and 50 years old. This study takes place in Madison, Wisconsin.

Are you an adult with severe asthma who plans to have bronchial thermoplasty treatment? This study is using a new imaging technique, called optical coherence tomography, to examine the airways in people with asthma before and after a treatment called bronchial thermoplasty. This treatment is minimally invasive and reduces asthma symptoms by using heat to shrink smooth muscle within the lungs. To participate in this survey, you must be between 18 and 60 years old. This study takes place in Boston, Massachusetts.

Are you an adult with asthma who is being treated with therapeutic proteins or is interested in trying this treatment? This study investigates the use of a treatment using therapeutic proteins in people with asthma and seeks to determine whether its use can lower inflammation in patients. To participate in this study, you must be between 18 and 80 years old. This study takes place in San Francisco, California.
