Could a simple chest strap replace invasive heart tests?
NCT ID NCT07453017
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests whether a non-invasive device called electrical impedance tomography (EIT) can accurately diagnose pulmonary hypertension, a serious lung condition. Currently, diagnosis requires an invasive procedure called right heart catheterization. Researchers will compare EIT readings to catheterization results in 120 patients to see if EIT can serve as a safer, bedside screening tool.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- Electrical Impedance Tomography (EIT)
- What this could lead to
- If successful, EIT could become a safe, non-invasive screening tool for pulmonary hypertension, reducing the need for invasive catheterization and enabling earlier diagnosis.
- What could go wrong
- This is an early diagnostic study, not a treatment trial. EIT may not be accurate enough to replace catheterization, and results may not apply to all patients with pulmonary hypertension.
