Primary
| Measure | Time frame |
|---|---|
| Main Objective: The primary objective of this trial is to investigate the efficacy of Angiotensin-II vs. standard of care on the biomarkers [TIMP-2]*[IGFBP7] in high-risk patients undergoing cardiac surgery.;Secondary Objective: • occurrence of AKI within 72h after cardiac surgery • occurrence of moderate and severe AKI within 72h after cardiac surgery • amount of volume application • transient (<72h) and persistent (<72h) AKI • fluid status • dose and duration of vasopressor use • creatinine clearance on day one after cardiac surgery • free-days through day 28 of vasoactive medications and mechanical ventilation • renal recovery at day 90 • 30-day, 60-day and 90-day mortality • length of ICU stay • length of hospital stay • use and duration of renal replacement therapy within hospital stay • use of RRT at days 30, 60, 90 • MAKE90 • Effect of ACEi/ARBs use on the AT II effect • Correlation between the severity of hyperreninemia and the AT II effect;Primary end point(s): • kidney damage after cardiac surgery identified by the difference between [TIMP-2]*[IGFBP7] levels 12h after randomization and [TIMP-2]*[IGFBP7] levels at randomization;Timepoint(s) of evaluation of this end point: 12 h after start of intervention | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): • occurrence of AKI within 72h after cardiac surgery (according to the KDIGO criteria) • occurrence of moderate and severe AKI within 72h after cardiac surgery (according to the KDIGO stage 2 and 3) • amount of volume application • transient (<72h) and persistent (<72h) AKI • fluid status • dose and duration of vasopressor use • creatinine clearance on day one after cardiac surgery • free-days through day 28 of vasoactive medications and mechanical ventilation • renal recovery at day 90 (renal recovery is defined as serum creatinine levels < 0.5 mg/dl higher than baseline serum creatinine (creatinine level before surgery) • 30-day, 60-day and 90-day mortality • length of ICU stay • length of hospital stay • use and duration of renal replacement therapy within hospital stay • use of RRT at days 30, 60, 90 • MAKE90 (major adverse kidney events consisting of mortality, dialysis dependency, persistent renal dysfunction (defined as serum creatinine = 2x compared to baseline value) at day 90 • Effect of ACEi/ARBs use on the AT II effect • Correlation between the severity of hyperreninemia and the AT II effect ;Timepoint(s) of evaluation of this end point: 72 hours after cardiac surgery 30 days after cardiac surgery 60 days after cardiac surgery 90 days after cardiac surgery | — |
