New heart scan could spare patients from invasive artery checks
NCT ID NCT05940285
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study is testing whether a special heart scan (dynamic SPECT) can accurately detect remaining blockages in heart arteries after a heart attack, compared to the current standard invasive procedure (FFR). Sixty adults with multiple blocked arteries will receive both tests one month after their heart attack. The goal is to see if the non-invasive scan can reliably replace the invasive one, making follow-up safer and more comfortable.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
Dynamic 99mTc-Tetrofosmin CZT-SPECT (a radioactive tracer used in a heart scan)
What this could lead to
If successful, this could allow doctors to use a simple, non-invasive scan instead of a risky invasive procedure to check for remaining blockages after a heart attack.
What could go wrong
This is a small pilot study with only 60 participants, so results may not apply to everyone. The new scan might not be accurate enough to replace the invasive test in all cases.
