The Role of Other Major Postoperative Complications in Determining Outcomes of Acute Kidney Injury After Coronary Artery Bypass Surgery
Main finding · MortalityResult — go to the resultHazard ratio 2.02 CI 1.10–3.70Authors' conclusion
AKI following CABG was not associated with short- and long-term mortality in the absence of major complications but predicted a higher risk of MACCE and postoperative chronic kidney disease.
Study context
- Population
- Consecutive patients undergoing isolated CABG at a single nationwide center, 2001–2020, excluding preoperative dialysis
- Participants
- 2,287 patients
- Exposure
- Acute kidney injury (AKI) vs No AKI
- AKIn = 459
- Outcome
- Short- and long-term mortality and MACCE
