Cardiac surgery-associated acute kidney injury requiring haemofiltration: The immediate postoperative phase is critical to achieve equivalent long-term survival

Postoperative AKI requiring haemofiltration is associated with poor outcomes following cardiac surgery. However, in patients surviving the acute postoperative phase, there was no significant difference in long-term survival compared to those who did not require haemofiltration. These findings underscore the importance of early recognition and management of acute kidney injury after cardiac surgery whilst offering a more nuanced understanding of long-term prognosis.
