Summary

This completed study tested whether a special ultrasound scan (IVUS) of plaque buildup in heart arteries can accurately diagnose reduced blood flow (functional myocardial ischemia). Researchers enrolled 105 adults with coronary artery disease and compared IVUS results to the standard FFR test. The goal was to see if IVUS plaque measurements could reliably identify blockages that need treatment.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

What this could lead to: If successful, this could provide a new, less invasive way to diagnose which heart artery blockages are serious enough to need treatment.
What could go wrong: This is a small, single-site study with only 105 participants. The results may not apply to all patients, and the method needs more testing before it can be widely used.
