New heart stress test aims to diagnose blockages without radiation
NCT ID NCT00894179
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested a new stress echocardiography method using regadenoson and atropine to diagnose coronary artery disease. It involved 45 adults scheduled for cardiac catheterization. The goal was to see if this faster, radiation-free approach could accurately detect significant blockages compared to standard angiography.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- regadenoson and atropine
- What this could lead to
- If successful, this could provide a faster, safer, and radiation-free way to diagnose blocked heart arteries.
- What could go wrong
- The study was terminated early with only 45 participants, so results are limited and may not apply to everyone. The method may not be as accurate as standard tests.
