Sound waves vs X-Rays: which guides heart stents better?
NCT ID NCT07616024
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study compares two ways to guide stent placement during emergency treatment for a severe type of heart attack (STEMI). About 2,500 patients will be randomly assigned to receive either standard X-ray guidance or ultrasound guidance (IVUS) during the procedure. The goal is to see if ultrasound guidance leads to fewer future heart-related events like death, repeat procedures, or another heart attack.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
Intravascular ultrasound (IVUS) procedure
What this could lead to
If successful, this could show that using ultrasound during emergency heart attack stenting reduces the risk of future heart problems or death.
What could go wrong
This is a large trial but still early in testing. The ultrasound guidance may not provide a clear benefit over standard care, and the procedure carries typical risks of catheter use.
