Cognitive Outcomes After On- Versus Off-Pump Coronary Artery Bypass Surgery

At baseline, lower cognitive function, older age, lower education, and ethnicity other than white were predictive of cognitive decline after CABG. Patients in both groups demonstrated low frequencies of cognitive impairment on individual tests at baseline and follow- up, and few patients in either group were classified as impaired at 1-year follow-up on individual tests. In general, the Randomized On versus Off Bypass study documented that neither on-pump nor off-pump CABG adversely impacts long-term brain function.
