This early study tests a new device called the A-FLUX Reducer for people with chest pain caused by small heart vessel disease (microvascular dysfunction). The device is placed in a vein near the heart to improve blood flow and reduce symptoms. About 30 adults with persistent ches…

This observational study will follow up to 1,000 adults with conditions like fainting, rapid heartbeat, or low blood pressure who have had or will have a procedure that adjusts nerve signals to the heart. Researchers will track whether symptoms return within a year. The goal is t…
