Summary

This trial tested a device called Barostim neo that stimulates nerves to help control blood pressure in people with advanced heart failure. Over 1,000 participants received either the device or standard medical care. The goal was to see if the device could reduce heart-related deaths and hospital stays, and improve quality of life.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: BAROSTIM NEO System (a device that activates baroreflex to regulate blood pressure)
What this could lead to: If successful, this device could offer a new way to manage advanced heart failure, reducing hospital stays and improving daily function.
What could go wrong: This is a completed trial, but results are not yet widely available. The device requires surgical implantation, which carries risks like infection or nerve injury. It may not work for everyone.
