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 a ventricular arrhythmia?
This study aims to evaluate the safety and effectiveness of low-energy shocks for the treatment of ventricular tachycardia and ventricular fibrillation. This approach will be tested during a catheter ablation or placement of an implantable cardioverter defibrillator (ICD). To participate in this study, you must be between 18 and 75 years old. This study is located in Minneapolis, Minnesota, and Austin, Texas.
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.
Have you been diagnosed with LAM? This study is trying to understand the genes and proteins that are responsible for causing lung damage in patients with LAM. To participate in this study, you must be between 16 and 99 years old and diagnosed with LAM. This study is located in Bethesda, Maryland.
Are you an adult female who has been diagnosed with LAM? This study is examining which delivery method of albuterol—inhaled or nebulizer—is better at improving lung function in adult women who have LAM. This study is located in Bethesda, Maryland.
Do you have LAM and would be willing to help research? This study aims to identify the right dose of sirolimus to treat people who have LAM. To participate in this study, you must be female, between 18 and 90 years old, and diagnosed with LAM. This study is located in Bethesda, Maryland.
Are you an adult woman who would like to help develop methods to prevent the worsening of LAM?
This study aims to discover whether earlier and longer treatment with a lower dose of sirolimus can help prevent LAM from getting worse over time. To participate in this study, you must be female, be at least 18 years old, and have been diagnosed with LAM. This study is located in Atlanta, Georgia; Boston, Massachusetts; Chicago, Illinois; Cincinnati, Ohio; Denver, Colorado; Nashville, Tennessee; Palo Alto, California; Philadelphia, Pennsylvania; and Seattle, Washington.
Do you or someone in your family have a lymphatic disorder such as LAM? This study is looking at the relationship between lymphatic disorders and gene variations found in the lungs, blood, and other parts of the body. Researchers hope this will improve our understanding of these types of disorders and how genetic factors affect them. Participants must be between 2 and 90 years old and either have a lymphatic disorder or be a relative of someone who does. This study is located at the NIH Clinical Center in Bethesda, Maryland.
Do you have tuberous sclerosis and want to help researchers better understand the disease? This study is investigating what causes multiple skin tumors to develop in people with tuberous sclerosis. To participate in the study, you must be at least 18 years old. This study is located at the NIH Clinical Center in Bethesda, Maryland.
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.
