Summary

This study is testing a new type of MRI, called hyperpolarized 13C MRI, to see if it can better identify which patients with heart disease will benefit from bypass surgery. The technique measures how the heart produces energy by tracking two simple molecules. Researchers will compare the results in healthy people and patients before and after surgery. If it works, this could help doctors make more precise treatment decisions.

What this could mean

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

Active substance: Hyperpolarized 13C MRI (imaging technique using a special contrast agent, pyruvate)
What this could lead to: If successful, this could lead to a more accurate way to select patients for bypass surgery, improving outcomes and avoiding unnecessary procedures.
What could go wrong: This is a small, early feasibility study with only 30 participants. The new MRI method may not prove better than existing scans, and results may not apply to all patients.
