Summary

This study looks at whether a pre-surgery test called FFR can predict how well arterial bypass grafts work six months after coronary artery bypass grafting (CABG). About 120 patients with multi-vessel heart disease will have an FFR test during their diagnostic angiogram. Six months after surgery, they get another angiogram to check graft function. The goal is to see if FFR values match graft health, which could guide future bypass decisions.

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
What this could lead to: If successful, this could help surgeons decide which arteries to bypass, potentially improving long-term graft function.
What could go wrong: This is an observational study, not a treatment trial. It only measures correlation, not outcomes. Results may not change practice directly.
