Patients with mild renal dysfunction had a higher incidence of postoperative acute kidney injury (AKI), at 26.1%, compared to 18.7% in normal renal function patients.
The study analyzed data from 1,097 patients over the medium term, with no significant difference in perioperative mortality at 1.3% for both groups.
Propensity score matching was used to balance patient differences in the cohort study design from two hospitals over two and a half years.
While renal dysfunction increased postoperative AKI risk, no difference was observed in long-term outcomes like all-cause mortality and major adverse cardiac events.

Cohort study evaluates increasing risk of AKI in CABG patients with mild renal dysfunction, suggesting careful monitoring is needed.

Wang et al. (2025) studied this question.
