Summary

This study compares two ways to guide stent placement during a heart attack: standard angiography (X-ray) versus a more detailed imaging method called optical coherence tomography (OCT). The goal is to see if OCT leads to fewer future heart problems, like repeat blockages or heart-related death. The trial will enroll 1,500 adults with a specific type of heart attack (STEMI) who are treated within 12 hours of symptoms.

What this could mean

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

Active substance
Optical coherence tomography (OCT) imaging guidance
What this could lead to
If successful, this could show that using OCT during heart attack treatment reduces the risk of future heart problems or the need for repeat procedures.
What could go wrong
This is a large trial but still early in testing a procedure, not a drug. The benefit may be small or not apply to all patients. Risks include those of the standard procedure itself.
