Discussion

Retrospective cohort analysis reveals that major complications alter the mortality impact of acute kidney injury.

AKI after CABG predicted higher 30-day mortality and long-term adverse outcomes, but complications altered this association.
Of 2287 patients, 459 developed AKI, with 203 also facing major complications, showing the intertwining effects on mortality.
Cox regression analysis indicated that while AKI typically worsens outcomes, the presence of other major complications mediates its effects on mortality.
Findings suggest that addressing major complications could improve long-term cardiovascular health and reduce kidney dysfunction post-surgery.

Heitmann et al. (2025) studied this question.
