Periodo de tiempo |

|
The occurrence of CSA-AKI
Periodo de tiempo: The assessment will be conducted from the end of the surgery until the 7th day after the operation
|
CSA-AKI is defined as: an increase of ≥26.5 µmol/L in serum creatinine (SCr) within 48 hours after cardiovascular surgery compared with the baseline, or an increase of ≥ 50% of the baseline value within 7 days after surgery.
|
The assessment will be conducted from the end of the surgery until the 7th day after the operation

|
The occurrence of severe CSA-AKI(i.e. AKI stage 2 or 3)
Periodo de tiempo: The assessment will be conducted from the end of the surgery until the 7th day after the operation
|
Acute kidney injury at stage 2 or stage 3 as defined by the KDIGO 2012 guidelines.AKI stage 2 is defined as:meet any of the following conditions:
AKI stage 3 is defined as: meeting any of the following conditions:
|
The assessment will be conducted from the end of the surgery until the 7th day after the operation
|
|
The occurrence of persistent acute kidney injury
Periodo de tiempo: 48 hours after the diagnosis of acute kidney injury
|
Persistent acute kidney injury is defined as acute kidney injury that persists for more than 48 hours after its initial diagnosis, based on serum creatinine and/or urine output according to KDIGO criteria.
|
48 hours after the diagnosis of acute kidney injury
|
|
Renal replacement therapy or in-hospital death
Periodo de tiempo: From the end of cardiac surgery until the date of first occurrence of renal replacement therapy or in-hospital death, whichever came first, assessed up to 1 year after cardiac surgery.
|
Receiving any form of renal replacement therapy (such as continuous renal replacement therapy, intermittent hemodialysis, etc.) or any in-hospital death caused by any reason.
|
From the end of cardiac surgery until the date of first occurrence of renal replacement therapy or in-hospital death, whichever came first, assessed up to 1 year after cardiac surgery.
|
|
CSA-AKI as defined by the AKIN standard
Periodo de tiempo: From the preoperative period to 48 hours after the operation
|
CSA-AKI as defined by AKIN: that is, the increase of serum creatinine within 48 hours is >26.5umol/L or > 50% of the baseline;
|
From the preoperative period to 48 hours after the operation
|
|
New CKD or progression of existing CKD
Periodo de tiempo: From the preoperative baseline assessment through 1 year after cardiac surgery
|
Chronic kidney disease (CKD) is defined according to the KDIGO 2024 guidelines.
CKD progression is defined as: an estimated decrease in glomerular filtration rate (eGFR) from baseline of more than 25%, or an average annual eGFR decrease rate of more than 5 ml/min/1.73m²
|
From the preoperative baseline assessment through 1 year after cardiac surgery
