Clinical Trials

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

Do you take medicine for high blood pressure or high blood cholesterol? This study will test a program that asks pharmacists to reach out to patients who have high blood pressure, high blood cholesterol, or diabetes and help them stick to their plans for taking and refilling their medicines as prescribed. To participate in this study, you must be between 18 and 75 years old. The study location is in Bloomington, Minnesota.

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.

Are you living with HIV and high blood cholesterol or high blood pressure? This study is evaluating a nurse-led reminder system to help people who have HIV stay on track with their heart medicines. Participants will have four visits with a nurse, who will help them manage their medicine schedule with telephone reminders. To participate in this study, you must be at least 18 years old; have HIV, high blood cholesterol, or high blood pressure or be taking medicines to manage these conditions; and have access to a telephone. This study is located in Cleveland, Ohio, and Durham, North Carolina.

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.

Has your doctor recommended right heart cardiac catheterization for you? This study is investigating new magnetic resonance imaging (MRI) techniques that use a guidewire to help position a heart catheter within the heart. MRI fluoroscopy shows pictures of the heart so that doctors can watch while they work. Using the guidewire during MRI may improve the procedure of heart catheterization. To participate in this study, you must be at least 18 years old, and your doctor must have recommended right heart catheterization for you. This study is located in Bethesda, Maryland.

Are you a Minnesota resident with hypertrophic cardiomyopathy? This study aims to find out how common it is for people with hypertrophic cardiomyopathy to also have sleep apnea. Hypertrophic cardiomyopathy is a disease that causes the heart muscle to thicken. Participants will also wear a heart rhythm monitor to help researchers learn whether sleep apnea is linked to arrhythmia. The study seeks healthy volunteers as well as participants in the Hypertrophic Cardiomyopathy Registry. To participate in this study, you must not have had a catheter ablation procedure to treat atrial fibrillation, had surgery to replace your heart valves, or been treated for sleep apnea. The study is located in Rochester, Minnesota.

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.

Have you been diagnosed with peripartum cardiomyopathy and are within 5 months of your due date? This study is evaluating the effectiveness of a medicine called bromocriptine to treat peripartum cardiomyopathy, or weakness of the heart muscle that occurs during or shortly after pregnancy. To participate in this study, you must be at least 18 years old, diagnosed with peripartum cardiomyopathy, and within 5 months of your delivery date. This study takes place in Pittsburgh, Pennsylvania.
