NCT ID: NCT02124109 Completed - Clinical trials for Rheumatic Heart Disease

The Genetic Basis of Acquired Heart Disease in Africa

Start date: April 3, 2014
Study type: Observational

Background: - An acquired heart disease is one that a person gets after they are born. Two of these are rheumatic heart disease (RHD) and endomyocardial fibrosis (EMF). They are found more commonly in people who live in Africa than in other places in the world. Researchers want to learn more about these diseases. They especially want to know what role genes and other factors play in them. Objective: - To identify genetic risk factors for RHD and EMF in sub-Saharan Africa. Eligibility: - Children and adults with RHD or EMF. - Healthy volunteers over age 10. Design: - Participants will come from existing study groups in Uganda and Nigeria. - Participants may be required to provide a sample of their DNA. They will do this with either a blood or saliva sample or a swab of the mouth. - Collected samples will be labeled with a code and sent to a lab in the United States for analysis. Remaining portions of participants samples will be stored for an unlimited period of time. They may be used in future studies. - Some genetic and health information from participants might be placed into one or more scientific databases. - Participant names and identifying information will be kept private. But there is a small chance someone could trace them from their genetic information.

NCT ID: NCT01160471 Completed - MRI Clinical Trials

Noninvasive Imaging of Heart Failure: A Pilot Study

Start date: July 1, 2010
Study type: Observational

Background: - Heart failure is a common cardiovascular disorder whose incidence increases with age, affecting up to 10% of people older than 65 years of age. As the population ages, the prevalence and cost of heart failure will continue to rise. Researchers are interested in using noninvasive imaging methods to better understand the symptoms and effects of heart failure. Objectives: - To conduct a noninvasive comparative imaging study of individuals with heart failure. Eligibility: - Individuals at least 18 years of age who have been diagnosed with heart failure (with at least mild symptoms and slight limitations on physical activity). Design: - This study will last approximately 2 years and will require four visits to the National Institutes of Health Clinical Center, with one screening visit and three study visits. - Participants will be screened with a full medical history and physical examination, as well as blood and urine samples. - Participants will have the following tests during each study visit: - Physical examination - Blood and urine samples - Cardiac magnetic resonance imaging - Cardiac computerized tomography to study the blood vessels in and leading to the heart - Echocardiogram to evaluate heart function - Electrocardiogram to measure heart electrical activity - The three study visits will take place 1 year apart. Participants will also receive follow-up phone calls 6 months after the first and second visits. - No treatment will be provided as part of this protocol.

NCT ID: NCT00483951 Terminated - Clinical trials for Myocardial Infarction

Cardiovascular Disease Screening

Start date: January 28, 2008
Phase: N/A
Study type: Interventional

This study will evaluate volunteers 18 years of age and older to see if they qualify for one of NHLBI s research studies. Tests include the following: - General medical evaluation, which may include blood tests, chest x-ray, electrocardiogram (ECG) and echocardiogram (heart ultrasound). - Other tests as appropriate, such as magnetic resonance imaging (MRI), cardiac computed tomography (CT scan of the heart), nuclear stress test and echocardiography stress test. - X-ray contrast studies of the heart and blood vessels. (These may be excluded in patients with kidney risk factors.)
