Metabolic markers to predict kidney injury after heart surgery
Part of Kidney & urinary, Women’s health & pregnancy clinical trials.
This study looks at how your body's metabolism (energy use) can predict if you'll get kidney damage after heart surgery. It aims to help doctors identify high-risk patients earlier so they can prevent or treat kidney problems sooner.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are scheduled for heart surgery that is not an emergency.
- Your surgery must be either with a heart-lung machine plus one kidney risk factor, or without a heart-lung machine (like simple bypass) plus two kidney risk factors.
- Kidney risk factors include being 70 or older, having diabetes on medication, mild-to-moderate kidney disease (eGFR 30–60), a history of protein in urine, heart failure, weak heart pumping (LVEF 40% or less), prior open-heart surgery, or certain complex surgeries.
- You must not have very poor kidney function (eGFR under 30 or on dialysis).
- You must not have acute kidney injury at the time of enrollment (except a brief one from contrast dye).
- You must not have had a kidney transplant, urinary blockage, advanced heart failure, HIV, blood cancer, or a life expectancy under 1 year.
