Beskrivelse
Inclusion Criteria:
- 1. Age no less than 18 years old;
- 2. Patients who underwent cardiovascular surgeries at Fuwai Hospital in Beijing from 2015 to 2025 and at Fuwai Hospitals in Central China, Yunnan and Shenzhen from 2022 to 2025;
- 3. At least one blood creatinine test should be conducted within 48 hours after the operation, and at least two blood creatinine tests should be conducted within one week after the operation.
Exclusion Criteria:
- 1. Lack of preoperative baseline creatinine;
- 2. Patients who developed AKI before surgery or whose AKI did not recover: The definition of AKI follows the KDIGO 2012 guideline;

Foranstaltningsbeskrivelse |
Tidsramme |
|---|---|---|
|
The occurrence of CSA-AKI
Tidsramme: 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

Tidsramme |
|---|---|---|
|
The occurrence of severe CSA-AKI(i.e. AKI stage 2 or 3)
Tidsramme: 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
Tidsramme: 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
Tidsramme: 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
Tidsramme: 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
Tidsramme: 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
