  • Research summary

    Patients undergoing cardiac surgery have a high risk of acute kidney injury (AKI), and patients who develop AKI after cardiac surgery have an increased risk of dying or developing chronic kidney disease and becoming dialysis dependent.
    At present, there are limited ways of determining the individual risk of AKI in patients scheduled for cardiac surgery. We believe that patients with reduced kidney function reserve have a higher risk of kidney disease during surgery. A preliminary small study in Vicenza, Italy showed that it was possible to measure kidney function reserve by giving patients a high protein meal and measuring kidney function before and after. In this study, patients who had limited kidney reserve had a higher risk of developing acute kidney injury after surgery.

    We would like to repeat this study to find out whether the assessment of kidney function reserve after a protein drink helps identifying those patients who are at highest risk of acute kidney injury and chronic kidney disease after cardiac surgery. If confirmed, high risk patients can be recognised earlier and hopefully acute kidney injury can be prevented.
