Condition: Heart Disease / High Blood Pressure
Investigator: Ajay Kirtane, MD, SM
Status: Currently Recruiting
We are doing this study to evaluate the real-world use of the Paradise Ultrasound Renal Denervation System indicated for patients who are unable to lower their blood pressure with lifestyle changes and medication. This is an FDA approved device. Involvement in the study is expected to last approximately 60 months. Patients will be asked to collect blood…
Condition: Nutrition
Investigator: Joshua Cook, MD, PhD
Status: Currently Recruiting
We are conducting a research study on the effect of high insulin levels on the buildup of excessive liver fat ("fatty liver disease") in people at risk for type 2 diabetes. We are seeking adult volunteers, ages 18-65, who have obesity with a body mass index of 30-45, and have been diagnosed with, or are at risk for, prediabetes and metabolic…

Investigator: Jacquelyn Taylor, PhD, MSN, BSN
Status: Currently Recruiting
Race-Based Stress Reduction and Resilience Program for African-American Women. Join this important research study to examine the effectiveness of an eight-week stress reduction program for older African-American women. To learn more contact 347-978-2871 or son_RiSEstudy@cumc.columbia.edu. Study Requirements: African-American female between 50-75 years old,…
Condition: Heart Disease / High Blood Pressure
Investigator: Daichi Shimbo, MD
Status: Currently Recruiting
The measurement of blood pressure used to determine if a person has high blood pressure (also known as hypertension) and whether their blood pressure is controlled while taking medications that lower blood pressure. For many people, blood pressure levels are different when measured in a provider's office versus during normal daily activities outside of…
Condition: Valve Disease / Tricuspid Valve Disease
Investigator: Susheel Kodali, MD
Status: Currently Recruiting
The goal of this early feasibility study is to gain initial insight into the basic safety and performance of transluminal (through the blood vessels) implantation of the PASCAL System's implant (composed of man-made materials). We are trying to evaluate the safety and performance of the PASCAL System with Optimal Medical Therapy (OMT) (also known as…
TTVR Early Feasibility Study in Patients with Symptomatic Severe Tricuspid Regurgitation - Medtronic
Condition: Valve Disease / Tricuspid Valve Disease
Investigator: Susheel Kodali, MD
Status: Currently Recruiting
This is a research study for patients who have Tricuspid Regurgitation (TR), a condition that occurs when the three leaflets of the heart's tricuspid valve do not close properly causing blood to leak backward with each heartbeat. Since some of the blood leaks backward, the heart has to pump more blood with each beat to push the same amount of blood…
Condition: Heart Disease / High Blood Pressure
Investigator: Steven Shea, MD
Status: Closed
We are working with researchers at Columbia University to test whether text messaging can be used effectively to help people with hypertension to control their blood pressure. If you are between the ages of 18 and 85 years and have a cell phone, you may be eligible to participate in this study. The study would involve a telephone call that would last about…
Condition: Valve Disease / Tricuspid Valve Disease
Investigator: Susheel Kodali, MD
Status: Closed
The Edwards Cardioband Tricuspid Valve Reconstruction FIT valve repair system is a prospective, single arm, multi-center study to evaluate the safety and performance of the Cardioband Tricuspid System. The Edwards Cardioband Tricuspid Valve Reconstruction System is intended for patients with tricuspid regurgitation deemed to be potential candidates for…

Condition: Nutrition
Investigator: Lena Mamykina, PhD
Status: Closed
We are conducting an academic study to understand how people solve problems related to health. In the study, participants will be presented with a hypothetical problem related to diabetes self-management and asked to use an online health application to explore information and propose a solution. We invite all participants between 18 and 65 years old, who…
Condition: Heart Disease / High Blood Pressure
Investigator: Daichi Shimbo, MD
Status: Closed
We are conducting a research study in adults to test whether blood pressure (BP) measured in a clinic setting without a technician present is comparable to blood pressure levels while awake outside of the clinic on an Ambulatory Blood Pressure Monitoring (ABPM) device. We will also test whether asleep blood pressure can be accurately determined using a home…
Condition: Valve Disease / Tricuspid Valve Disease
Investigator: Susheel Kodali, MD
Status: Closed

Since some of the blood leaks backward, the heart has to pump more blood with each beat to push the same amount of blood forward.…
Condition: Nutrition
Investigator: Lena Mamykina, PhD
Status: Closed
Seeking participants for a study about how individuals prefer to receive nutrition recommendations to support health management and preferences for visualizing health data. Participants will be invited to complete a 60-minute session to answer questionnaires and evaluate different styles of nutrition recommendations. Alternatively, they will complete one 60…

Condition: Heart Disease / High Blood Pressure
Investigator: Nour Makarem, PhD
Status: Closed
We are currently looking for men and non-pregnant women aged 40 years and above to participate in an at-home study on sleep and activity patterns in relation to blood pressure and blood glucose. Participants should not have critical/severe illness and should not be on dialysis or have a pacemaker or other implanted medical device. You must be willing to…
Condition: Heart Disease / High Blood Pressure
Investigator: Ajay Kirtane, MD, SM
Status: Closed
RADIANCE II is a randomized, double-blind, sham-controlled, single cohort study designed todemonstrate the effectiveness (how well it works) and safety of the Paradise Renal Denervation System in hypertensive subjects (subjects with high blood pressure).
Condition: Heart Disease / High Blood Pressure
Investigator: Ajay Kirtane, MD, SM
Status: Closed
The study has been designed to demonstrate the efficacy and safety of the Paradise Renal Denervation System when treating patients with high blood pressure known as hypertension. When blood pressure is persistently elevated and pushes against the walls of the artery over a long period of time it is known to cause Hypertension. The Paradise Renal Denervation…
Condition: Heart Disease / High Blood Pressure
Investigator: Ajay Kirtane, MD, SM
