      Breaking up Prolonged Sedentary Behavior to Improve Cardiometabolic Health
      Recruiting
                          New York
        Are you a healthy adult who wants to join a study about less sitting? You might qualify for this research. Researchers are testing if walking breaks can improve cardiovascular health, like blood pressure and glucose (sugar) levels. To join, you must be 18 years old and have no long-term health issues or not be taking medications for blood pressure or diabetes. Participants will have to go to the study site for a 9-hour visit and walk on a treadmill during the day. The study is taking place in New York City, New York.

                          New York
        Do you have high blood pressure? In this clinical trial, researchers are studying different ways to improve home blood pressure monitoring. You may be able to participate if you are between 18 and 85 years old and diagnosed with high blood pressure. Participants will work closely with clinicians or other healthcare providers to schedule appointments, coordinate care, measure blood pressure, answer your questions, and treat your high blood pressure. The study is taking place in Rochester, New York.

    Pathophysiology of Orthostatic Intolerance
      Recruiting
                          Tennessee
        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.

    Hemodynamic Mechanisms of Abdominal Compression in the Treatment of Orthostatic Hypotension in Autonomic Failure
      Recruiting
                          Tennessee
        Do you have low blood pressure due to primary autonomic failure from a medical condition such as Parkinson disease, multiple system atrophy, or pure autonomic failure? Autonomic failure is caused by problems with a part of the nervous system called the autonomic nervous system. People with this condition can suffer debilitating low blood pressure upon standing. This study is testing the use of compression garments compared with a medicine called midodrine to improve blood pressure. To participate in this study, you must be between 18 and 80 years old and have low blood pressure when standing. This study takes place in Nashville, Tennessee.
