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.

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.
