Gut bacteria may foretell kidney danger after heart surgery
NCT ID NCT07738796
First seen Jul 31, 2026 · Last updated Jul 31, 2026
Summary
This study looks at whether the bacteria in your gut and the substances they produce can help predict a serious complication called acute kidney injury (AKI) after heart surgery. Researchers will collect stool and blood samples from about 180 adults before and after their operation to analyze these gut-related markers. The goal is to build a risk model that could identify high-risk patients early, potentially leading to preventive measures and better recovery.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- No drug or device is being tested. This observational study collects stool and blood samples to analyze gut bacteria and their byproducts.
- What this could lead to
- If successful, this could lead to a simple test that predicts which heart surgery patients are at risk for kidney injury, enabling earlier prevention and better outcomes.
- What could go wrong
- This is an early, observational study, so it cannot prove cause and effect. The model may not be accurate enough for widespread use, and findings may not apply to all patients.
