Are you an adult who has uncontrolled high blood pressure? This study will see whether an early notification system for health professionals can help manage patients’ high blood pressure, especially among those who have had a stroke or have an increased risk of stroke. To participate in this study, you must be between 18 and 85 years old and have high blood pressure that is not controlled by medicine and lifestyle changes.

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 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.
