For patients with impaired renal function, performing CABG off-pump rather than on-pump appears to improve outcomes, a retrospective study showed. Across the range of renal function, off-pump CABG was associated with a slightly lower rate of in-hospital death or the need for renal replacement therapy compared with on-pump CABG (1.8% versus 2%), according to Lakhmir Chawla, MD, of George Washington University Medical Center, and colleagues.
