Clinical Trials

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 stable angina and myocardial bridging but not obstructive coronary artery disease (CAD)? This study aims to help improve treatments for people that have angina in the absence of obstructive CAD. Angina without CAD affects millions of people but remains underdiagnosed and treatments are lacking. To participate in this study, you must be between 18 and 80 years old. This study takes place in Stanford, California.

Are you scheduled for open-heart surgery for your aortic valve? This study aims to look at changes in inflammation and gene activity while surgery patients are on a heart-lung bypass machine. To participate in this study, you must be at least 20 years old and be scheduled for aortic valve surgery, either with or without coronary artery bypass grafting (CABG). This study is located in Boston, Massachusetts.

Did you develop atrial fibrillation after coronary artery bypass graft (CABG) surgery? Did you develop atrial fibrillation after a coronary artery bypass grafting (CABG) surgery? This study is looking at how well oral anticoagulation medicines work to prevent complications, such as blood clots and heart attack, for patients who experience post-operative atrial fibrillation (POAF). This study is in multiple locations around the country.

Do you or your child have dyslipidemia? This study is exploring how different diagnostic tests can help us understand how lipid disorders, including high blood cholesterol and high blood triglycerides, affect the body. Information from this study may help improve the way lipid disorders are diagnosed or treated in the future. Participants must be at least 2 years old. This study is located in Bethesda, Maryland.

Do you or your child have obesity and high blood cholesterol or triglycerides? This study is testing the use of a statin in young people to see whether early treatment of high blood cholesterol can affect the risk of developing plaque in blood vessels. Participants in this study must be age 10-17, have a body mass index (BMI) in the obese range, be fluent in English, and not be pregnant.

Do you or your child have dyslipidemia? This study is exploring how different diagnostic tests can help us understand how lipid disorders, including high blood cholesterol and high blood triglycerides, affect the body. Information from this study may help improve the way lipid disorders are diagnosed or treated in the future. Participants in this study must be at least 2 years old. The study is being conducted in Bethesda, Maryland.

Are you an adult who is healthy or has problems with the level of cholesterol or other lipids in the blood? This study is gathering information on the risk factors for very high or very low levels of lipids, or fats, in the blood. Researchers will collect participants’ demographic information, medical history, and blood samples. To participate in this study, you must be at least 18 years old. This study takes place in Dallas, Texas.

Do you or a loved one have pneumonia? This study will test whether combining two medicines to reduce inflammation of the airway and to keep it open may help prevent respiratory failure in people who have pneumonia. To participate in this study, you must be at least 18 years old and have severe pneumonia with low blood oxygen levels.

Do you have symptoms of a lung disease (such as long-term wet cough, bronchiectasis, or recurrent pneumonia) with no genetic diagnosis? This study aims to develop new ways to diagnose primary ciliary dyskinesia (PCD) or primary immune deficiency (PID), two conditions that can have similar symptoms. Researchers will combine information from genetic testing, lung imaging, and lung function tests to diagnose and tell the difference between these two conditions. Participants in this study must be 5 to 45 years old and must have symptoms of a serious lung disease but no diagnosis. This study is taking place at multiple locations in the United States and in Canada, including the NIH Clinical Center in Bethesda, Maryland.
