About this trial
The goal of this prospective observational study is to define a risk profile for cardiovascular surgery associated acute kidney injury (AKI), using clinical patient characteristics, operation parameters as well as blood and urine laboratory values.
The main question it aims to answer is:
• Does a combination of the factors mentioned above better predict patient outcome than classical factors used to date in clinical practice?
Participants of this study are adults aged 18 and above who are scheduled for elective heart or main artery surgery, and who have given written informed consent.
