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.

Does your developing baby have a heart defect? Have you had a stillborn baby? This study tests a new technology to measure fetal heart activity and find possible problems early. These problems include fetal arrhythmia and conduction disorders such as Brugada syndrome. To participate in this study, you must be at least 18 years old and pregnant, and have one of five high-risk complications of pregnancy: a fetus with a major congenital heart defect, hydrops, or gastroschisis; a previous unexplained stillbirth; or twins who share a placenta. This study is located in Madison and Milwaukee, Wisconsin.

Have you been diagnosed with orthostatic intolerance? This study aims to find out how the body’s regulation of basic functions, such as heart rate and blood pressure, is altered in people who have orthostatic intolerance. This condition, which has an unknown cause, is characterized by a racing heartbeat, dizziness, lightheadedness, and other symptoms that occur when a person stands up. To participate in this study, you must be between 18 and 80 years old and have orthostatic intolerance. This study is located in Nashville, Tennessee.

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.
