Are you an African American woman at risk for diabetes? This study is testing whether using mobile health technology, such as smartphone apps and activity monitors, can help increase physical activity in African American women who are at risk for diabetes. To participate in this study, you must be an African American woman between 25 and 75 years old, have evidence of insulin resistance, and live in Prince George’s County, Maryland, or Ward 5, 7, or 8 in Washington, D.C.

Do you have a heart or blood vessel disease, such as peripheral artery disease? This study aims to collect data and samples from people who have a heart or blood vessel disease. This may include blood tests, ultrasound exams, and heart and lung tests. Family members and healthy people may also participate. The results may help researchers better understand PAD and other heart and blood vessel diseases. Participants must be at least 2 years old. Women who are pregnant may not take part in some study activities. This study is located in Bethesda, Maryland.

Are you at least 21 years old, and do you have heart failure? This study aims to better understand why heart failure can make it hard to exercise and perform daily activities. This complication is called exercise intolerance. Participants in the study will complete physical activities and then undergo magnetic resonance imaging (MRI) to look for changes in the chemicals the body uses for energy. To participate in this study, you must be at least 21 years old, diagnosed with heart failure, and be medically stable. This study is located in Baltimore, Maryland.
