New magnetic heart scanner could speed up ER heart attack diagnosis
NCT ID NCT06095557
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested a portable, unshielded magnetocardiography (MCG) device in the emergency department to see if it could reliably detect heart attacks. 124 patients with symptoms of acute coronary syndrome participated. The main goal was to see if the device could collect usable data in a busy ER setting, with a secondary aim of distinguishing high-risk from low-risk patients.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- magnetocardiography (MCG) device
- What this could lead to
- If successful, this device could help emergency doctors quickly identify patients having a heart attack, potentially speeding up treatment.
- What could go wrong
- This is a small, early feasibility study focused on whether the device works in a busy ER, not on whether it improves patient outcomes. It may not be accurate enough for real-world use.
