New wireless catheter could spot hidden heart disease in chest pain patients
NCT ID NCT07453381
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests a new wireless pressure microcatheter to diagnose coronary microvascular dysfunction (CMD) in people with chest pain but no major artery blockages. Researchers will compare the device's measurements to heart MRI scans in 114 participants. If accurate, it could offer a simpler way to detect this often-missed condition.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
multi-sensor wireless pressure microcatheter
What this could lead to
If successful, this could provide a more accurate and less invasive way to diagnose coronary microvascular dysfunction, helping doctors identify the cause of chest pain in patients with clear arteries.
What could go wrong
This is an early-stage study with only 114 participants, and the device's accuracy is being compared to an imaging reference. It may not prove superior or widely applicable.
