Clinical Trials

Do you have heart failure that is well controlled through medication and attending regular appointments with your healthcare provider? This clinical trial is testing a dietary supplement taken by mouth twice a day for five days to see if it can help patients with heart failure. You must be at least 18 years old to participate. The study is taking place in New Haven, Connecticut.

Do you have heart failure? In this clinical trial, researchers are using images of the heart and blood tests to learn more about Black and Hispanic patients with heart failure. You may be able to participate if you are at least 60 years old; of Black, Hispanic, or Caribbean origin; and have been diagnosed with heart failure. The study is taking place in locations in Connecticut, Massachusetts, and New York.

Are you an adult with heart failure and an implanted CardioMEMS pulmonary artery pressure (PAP) monitor? This study is investigating whether psychological stress can make the symptoms of heart failure worse. Participants of this study will have their blood pressure monitored and their blood drawn after undergoing mental stress in a controlled setting, within a laboratory. To participate in this study, you must be at least 18 years old. This study takes place in New Haven, Connecticut.

Do you have heart failure and need treatment with intravenous (IV) diuretics? This study is exploring the use of chloride supplementation in people with heart failure who require treatment with IV diuretics, which are used to help rid your body of excess water and salt. To participate in this study, you must have heart failure with signs of volume overload (rales, edema, elevated jugular venous pressure [JVP], or weight gain of at least 5 pounds) requiring treatment with IV diuretics. This study takes place in New Haven, Connecticut.

This study evaluates a sensor-controlled digital game (SCDG) to motivate self-management behaviors of weight monitoring and physical activity in adults with heart failure (HF). Half of the participants will receive the SCDG app and weight monitoring and physical activity sensors and the other half will receive only the weight monitoring and physical activity sensors.

The overall objective of research is to test, adapt, refine and validate the HEMOTAG® system to be used outside the usual medical care environments to reduce hospital readmissions.

Are you a Hispanic father with a child between 5 and 11 years old? If so, would you be interested in learning how to prevent obesity for you and your child? Researchers are studying whether a father-child together program helps Hispanic dads and their children learn and use healthy behaviors to prevent obesity. You may be able to join if you are 65 or younger and have a child who is between 5 and 11 years old. Stepfathers, grandfathers, uncles, or older brothers may be able to join as well. The study is taking place in Houston, Texas.

Do you want to help find new treatments for heart failure with preserved ejection fraction? This study is testing whether a medicine called spironolactone can help treat heart failure with preserved ejection fraction when paired with the standard treatment. Spironolactone helps to remove excess water and sodium from the body. To participate in this study, you must be between 50 and 99 years old and diagnosed with heart failure with preserved ejection fraction.

Does your child have higher triglyceride levels but normal cholesterol levels? This study is testing whether a protein supplement called carnitine can help prevent blood vessel stiffness in teenagers who have metabolic syndrome or other risk factors for heart and blood vessel diseases. Participants in this study must be between 13 and 19 years old and have moderate to high blood triglyceride levels but normal blood cholesterol levels. This study takes place in Houston, Texas.

Are you an adult who has overweight or obesity and would be interested in a weight-loss study? This study is testing whether a medicine called phentermine is safe and effective for treating obesity over a long period. This study has multiple locations in the United States.
