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.
This trial is testing a new method called Vessel-FFR, which calculates how severe a heart blockage is using regular imaging photos taken during a routine heart procedure. Instead of requiring an extra wire and medication to measure pressure inside your vessel, this new technique analyzes the images your doctor already takes to figure out if your blockage needs treatment.
Currently, doctors use an invasive pressure wire test to determine if heart blockages need treatment, but this requires extra time, medication that can cause side effects, and additional steps during the procedure. The new imaging method aims to give doctors the same information without these extra steps, making the procedure simpler and safer for patients.

If you join this trial, you will undergo a heart imaging procedure where doctors will use either the new imaging method or the standard pressure-wire test to evaluate your blockages and determine if treatment is needed. The study will then track your health outcomes over time to see how well each method guides treatment decisions. Your participation helps doctors understand whether this simpler imaging approach works as well as the standard procedure.
