Clinical Trials

Do you have coronary heart disease or are you healthy and would like to participate in research? This study is comparing how well two types of magnetic resonance imaging (MRI) scanners can detect different types of heart diseases, such as coronary heart disease, heart failure, congenital heart disease, and heart valve disease. The new type of MRI scanner in this study uses less energy than a traditional scanner and may be suitable for people who have metal devices in their bodies. This study is located in Bethesda, Maryland.

Are you interested in helping researchers understand what causes heart failure? The study is using a technique called magnetic resonance spectroscopy (MRS) during a cardiac magnetic resonance imaging (MRI) scan to determine whether energy metabolism is disrupted in heart failure and whether this contributes to poor heart function. To participate in this study, you must be at least 18 years old and either be healthy or have coronary artery disease, dilated cardiomyopathy, or left ventricular hypertrophy. The study is located in Baltimore, Maryland.

Are you at least 21 years old, and do you have heart failure? This study aims to better understand why heart failure can make it hard to exercise and perform daily activities. This complication is called exercise intolerance. Participants in the study will complete physical activities and then undergo magnetic resonance imaging (MRI) to look for changes in the chemicals the body uses for energy. To participate in this study, you must be at least 21 years old, diagnosed with heart failure, and be medically stable. This study is located in Baltimore, Maryland.

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.

Are you an adult with ischemic or non-ischemic cardiomyopathy? This observational study will group and follow patients at a higher risk for sudden cardiac death (SCD) who receive an implantable cardioverter defibrillator (ICD) pulse generator replacement as a prevention measure. The study hypothesizes that abnormalities of the heart, some of which are genetically determined, can be used to identify patients at high risk of SCD. To participate in this study, you must be between 18 and 85 years old and have ischemic or non-ischemic cardiomyopathy. You must also be getting your initial ICD implant for primary prevention or a programmed generator replacement if the ICD was originally implanted for SCD primary prevention. The study takes place in Baltimore, Maryland; Richmond, Virginia; and Washington, DC.

Are you able to have a magnetic resonance imaging (MRI) scan and want to help people with heart failure? This study is developing new methods for imaging the heart and blood vessels using MRI to improve how healthcare providers diagnose people with heart failure. This study takes place in Maryland and Washington, DC.

Do you have coronary artery disease, dilated cardiomyopathy, or left ventricular hypertrophy or want to help people with those conditions? This study is using a magnetic resonance imaging (MRI) scanner to measure heart metabolism, which provides the chemical energy that is needed for the heart to function normally. Researchers want to determine whether energy metabolism is reduced in heart failure and whether that contributes to the poor heart function. This study takes place in Baltimore, Maryland.

Do you have heart failure with preserved ejection fraction (HFPEF)? This study is testing the efficacy of a diuretic medicine called spironolactone that stops your body from absorbing too much salt and keeps your potassium levels from dropping too low. Participants of this study must be between 50 and 99 years old and already taking diuretic medicine. This study takes place in multiple locations across the United States and Sweden.
