Summary

This study will follow 5,000 adults undergoing heart surgery to develop a way to predict acute kidney injury (AKI) early. Researchers will collect blood and urine samples along with clinical data to build a warning model. The goal is to identify high-risk patients sooner and improve their outcomes. This is an observational study, meaning no new treatments are being tested.

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 lead to a tool that helps doctors identify patients at high risk for kidney injury after heart surgery, allowing for earlier and more personalized care.
What could go wrong
This is an observational study, not a treatment trial. It will not test any new drug or intervention, so it cannot directly improve outcomes. The model may also not be accurate enough for widespread use.
