Summary

This study looks at whether a special imaging technique called Quantitative Flow Reserve (QFR) can help predict how well a blood vessel graft will work after coronary artery bypass surgery. Researchers will follow 110 patients for one year after surgery to check if the grafts stay open and if patients have fewer heart problems. The goal is to see if QFR can guide surgeons to choose the best vessels for grafting.

What this could mean

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

What this could lead to: If successful, this could show that using QFR before surgery helps doctors choose better graft vessels, potentially reducing heart complications after bypass surgery.
What could go wrong: This is an observational study, not a treatment trial. It cannot prove cause and effect, and results may not apply to all patients. The sample size is small.
