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.

This study evaluates a home-based blood pressure monitoring (HBPM) program that provides longitudinal health education, empathic guidance, monitoring, and adaptable patient-centered coaching to rural individuals. Participants in this study will be randomized to receive (1) HBPM with the intervention; or (2) the control, consisting of HBPM and a smartphone with a general health application (WebMD).

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.

This study aims to learn about the effects of continuous positive airway pressure (CPAP) on people with autonomic failure and high blood pressure when lying down (supine hypertension) to determine if it can be used to treat their high blood pressure during the night. CPAP (a widely used treatment for sleep apnea) involves using a machine that blows air into a tube connected to a mask covering the nose, or nose and mouth, to apply a low air pressure in the airways.

This research is being done to learn if a smartphone app with and without a just in time adaptive intervention (JITAI) can help patients with hypertension manage their sodium intake and improve their blood pressure.

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

The purpose of this study is to find out why patients with chronic kidney disease (CKD) have poor exercise capacity and to explore what causes an increase in blood pressure during exercise.
