Oliveira and colleagues retrospectively analyzed outcomes for 1,628 patients who underwent on-pump coronary artery bypass grafting at a single center in Brazil over a six-year period. They divided patients into quartiles based on their preoperative creatinine levels, finding a higher mortality rate in the highest creatinine quartile than in the lowest two quartiles. Additionally, variance of more than 0.4 mg/dL between the creatinine level measured at admission and the highest level measured in the intensive care unit was associated with a greater risk of death for patients in all quartiles.
