Do you have heart failure with reduced ejection fraction (HFrEF) and an implantable cardioverter defibrillator (ICD)? This study is testing the effectiveness of thyroid hormone therapy with a medicine called liothyronine (LT3) in individuals HFrEF. To participate in this study, you must be at least 18 years old and have Class I, II, or III heart failure. This study takes place in Philadelphia, Pennsylvania.

Are you an adult with mild heart failure (HF) and left bundle branch block (LBBB)? LBBB is a heart condition in which there is a delay or blockage of electrical signals to the left side of the heart. This study is exploring the use of a treatment called cardiac resynchronization therapy (CRT) in people with HF and LBBB. To have CRT, participants must be willing to have an implanted device, called a biventricular pacemaker, that helps the chambers of the heart work together to pump blood more efficiently. To participate in this study, you must be at least 18 years old. This study takes place in Rochester, Minnesota.

Are you an adult with pulmonary arterial hypertension (PAH) and currently taking vasodilators? This study is testing the efficacy of a new medicine called famotidine for people with PAH. Participants in this study must be between 18 and 80 years old and willing to take famotidine or a placebo for 6 months. This study takes place in Seattle, Washington.

Do you have heart failure and feel that your condition is harming your mental and physical well-being? This study is testing the use of an intervention called positive psychology–motivational interviewing (PP-MI). Researchers are exploring whether this 12-week intervention delivered by phone and text message can improve the physical and mental health of people with heart failure. To participate in this study, you must be at least 18 years old. This study takes place in Boston, Massachusetts.

Are you a current patient at Massachusetts General Hospital or Brigham and Women’s Hospital with clinical depression and heart failure or unstable chest pain (called angina)? This study is investigating whether 26 weeks of education and increased monitoring from healthcare managers improves psychiatric and heart symptoms better than self-managed care. This study takes place in Boston, Massachusetts.

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.

Have you experienced a cardiac event in the past 6 months? This study assesses the efficacy of combining center-based and remote- or home-based cardiac rehabilitation sessions. Many patients who require cardiac rehabilitation, including those with angina myocardial infarction, heart failure, heart valve disease, and coronary heart (artery) disease, do not complete the necessary amount of rehabilitation sessions when done in a center-based environment. Researchers are investigating whether a combination approach will help. To participate in this study, you must be between 18 and 85 years old. This study takes place in Detroit, Michigan.

Do you or your child have a platelet, bleeding, or white blood cell disorder? This study is looking at people who have platelet or other blood disorders. The researchers will use a blood sample to look for problems with platelets and a possible genetic cause in the participant’s DNA or RNA. To participate in this study, you must be a child or adult who either is healthy or has a platelet disorder, coagulation disorder, or white blood cell disorder. This study is located in New York, New York.

Does your infant have a low platelet count? This study is investigating the safety and efficacy of platelet transfusion as a treatment for infants with thrombocytopenia. Researchers are looking at the positive effects of platelet transfusion against the negative effects, such as the release of inflammatory molecules and the formation of blood clots. To participate in this study, your child must be younger than 6 months old and have a low platelet count (less than 100 × 109/L). This study takes place in Boston, Massachusetts.

Does your infant have a low platelet count? This study investigates immature platelet counts as a marker for bleeding risk in newborns with thrombocytopenia, compared with platelet counts alone. Immature platelets are the most recently produced platelets and may be a better marker of platelet production. To participate in this study, you must have a newborn who is less than 32 weeks’ gestational age, has a birth weight greater than 500 grams, and has a platelet count less than 100 × 109/L. This study takes place in multiple locations in the United States, the Netherlands, and Sweden.
