H-Guard · In development
Detect earlier.
Protect the heart.
We’re developing a long-term implant to detect early biochemical signs of a heart attack — with the aim of enabling treatment before irreversible damage.

The sensing principle
Listening to the heart’s chemistry.
At the core of H-Guard is a ceramic sensing element being developed to convert local potassium differences into an electrical signal.
By comparing blood leaving the heart muscle with a reference inside the heart, we aim to recognise changes at their source and turn them into an actionable warning.
