The NHLBI leads or sponsors studies for patients who have heart, lung, blood, or sleep related diseases or disorders. Find studies for diseases and conditions and see if you or a loved one is eligible.
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.
Are you an adult with mild heart failure and a left bundle branch block? This study will test whether a type of pacemaker called a cardiac resynchronization device can help the heart pump more blood in people who have mild heart failure (HF) and left bundle branch block. In the study, participants will have a cardiac resynchronization device implanted. This study is located in Bethesda, 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.
Do you have heart failure with reduced ejection fraction and thyroid problems?
This study will test whether hormone therapy with liothyronine is safe and effective for treating people who have heart failure with reduced ejection fraction and low triiothyronine (T3) syndrome. Low T3 syndrome is a type of thyroid hormone that helps control many functions of your body. To participate in this study, you must be at least 18 years old and diagnosed with heart failure with reduced ejection fraction. This study is located in Philadelphia, Pennsylvania.
Are you a professional caregiver for an adult who has serious heart failure?
This study is testing whether electronic educational resources, in addition to in-person training , help home aids be more knowledgeable and confident in caring for adults who have serious heart failure. To participate in this study, you must be between 18 and 75 years old, be employed at Visiting Nurse Service of New York's Partners in Care agency, and care for an adult who has heart failure. This study is located in New York, New York.
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.
Are you an adult with ischemic cardiomyopathy? This study is investigating ways to prevent sudden cardiac arrest in people with ischemic cardiomyopathy. Researchers in this study are also working to determine which patients could benefit from an implantable cardioverter defibrillator, a device that is connected to the heart that can detect and stop irregular heartbeats called arrythmias. To participate in this study, you must be 18 years old or older and have ischemic cardiomyopathy. This study takes place in Buffalo, New York.
