Clinical Trials

Has your doctor recommended right heart cardiac catheterization for you? This study is investigating new magnetic resonance imaging (MRI) techniques that use a guidewire to help position a heart catheter within the heart. MRI fluoroscopy shows pictures of the heart so that doctors can watch while they work. Using the guidewire during MRI may improve the procedure of heart catheterization. To participate in this study, you must be at least 18 years old, and your doctor must have recommended right heart catheterization for you. This study is located in Bethesda, Maryland.

Are you an adult who does not have high blood pressure and is interested in research? This study will investigate how the brain regulates the body’s response to stress and how infection with HIV or pre-hypertension affects regulation. Your heart and brain activity will be measured while you are at rest, during a mentally stressful task, and while you feel angry. The study will also test whether a breathing exercise improves regulation. People with and without HIV and pre-hypertension will be included. To participate in this study, you must be between 21 and 65 years old and not have high blood pressure. This study is located in Miami, Florida.

The study team will conduct a cluster randomized control trial in up to 22 NYU primary care practices to assess the effectiveness and implementation of the multicomponent intervention on medication adherence and blood pressure control for patients who are non-adherent to antihypertensive medications.

The goal of this project is to develop and pilot test a research protocol to assess the influence of a health information behavior enhanced intervention on self-management, blood pressure control, and brain activity in African American women with hypertension. This work will identify characteristics of African American women that are associated with improved self-management and decreased blood pressure, and subsequent reduction of risk of heart disease and premature death. The results of this project will have direct impact in informing interventions to improve blood pressure control, by advancing our knowledge of brain activity associated with behavior change in African American women with hypertension in the metro-Detroit area, and ultimately everywhere.

The study aims to determine the minimally effective dose combination(s) of frequency and duration needed to provide cardiometabolic benefit during an 8-hour experimentation period.

Recent evidence supports lymphatic regulation of tissue sodium handling, however fundamental gaps persist in knowledge regarding the role of lymphatics in human diseases of sodium dysregulation. The goal of this work is to apply novel, noninvasive imaging tools to measure relationships between lymphatic function and tissue sodium in patients with well-characterized lymphedema. Findings are intended to inform mechanisms of lymphatic clearance of tissue sodium, and provide novel imaging biomarkers of lymphedema progression and treatment response.

The purpose of this study is to learn more about the effects of abdominal compression and the medication midodrine, two interventions used for the treatment of orthostatic hypotension (low blood pressure on standing), on hemodynamic markers of cardiovascular risk. The study will be conducted at the Vanderbilt University Medical Center and consists of a screening and 2 testing days, one with abdominal compression and one with midodrine. The total length of the study will be about 5 days.

The purpose of this research is to learn about how salt in the diet influences blood pressure in young adults who were born prematurely.

The overall goal of this study is to identify and rigorously evaluate strategies for implementing and sustaining team-based home blood pressure monitoring (TB-HBPM) within primary care.
