Read our Coronary Artery Disease research guide →This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
When you have a heart attack, doctors often find partially blocked arteries in addition to the main blockage that caused it. This trial is testing a new strategy for deciding which of these smaller blockages need treatment. Instead of using a functional blood flow test (FFR), doctors in this study will use advanced imaging called OCT (optical coherence tomography) — a special camera that looks inside your artery — to see if the blockage has features that make it risky, and then decide whether to place a stent to open it up.
Right now, doctors aren't sure whether functional blood flow testing or advanced imaging is the better way to decide if these smaller blockages should be treated during a heart attack. Recent research suggests that the imaging approach may be better at finding blockages that are truly dangerous and likely to cause problems, so this trial is testing whether using this imaging-guided approach actually prevents future heart attacks and saves lives.
You will undergo advanced imaging (OCT) of your heart arteries to look for signs of dangerous blockages. Based on what the imaging shows, your doctor will decide whether to place a stent in these blockages or simply monitor them. You will be randomly assigned to either the imaging-guided approach or the standard blood flow testing approach. You will need to take blood-thinning medications as prescribed and return for follow-up visits to monitor your heart health over time.
