Summary

This study looks at whether doing a CT scan of the heart's arteries before the usual catheter procedure can lower the risk of death, heart attack, stroke, or hospital stays in people who have had bypass surgery. About 1000 participants will be randomly assigned to get the CT scan first or go straight to catheterization. The goal is to see if the CT-guided approach is safer and more effective.

What this could mean

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

Active substance: Computed Tomography Coronary Angiography (CTCA) scan
What this could lead to: If successful, this could make heart imaging safer and more effective for bypass patients, potentially reducing complications and hospital visits.
What could go wrong: This is a mid-stage trial with 1000 participants, so results may not apply to all patients. CTCA might not improve outcomes or could lead to extra testing.
