Summary

This study looked at using a special wire that measures blood pressure inside heart arteries (called FFR) to help doctors decide which blockages to treat with stents. It included 438 people with two or more blockages in the same artery. The study was stopped early, so the results are not complete, but the goal was to see if FFR guidance reduces heart-related deaths, heart attacks, or the need for repeat procedures.

What this could mean

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

Active substance: Fractional flow reserve (FFR) measurement during stent placement
What this could lead to: If successful, this could show that FFR guidance helps doctors decide which blockages to treat, potentially reducing heart attacks and repeat procedures.
What could go wrong: The study was terminated early, so results are limited. It was observational, not a randomized trial, so it cannot prove cause and effect.
