Off-pump coronary artery bypass graft surgery results in
less neurocognitive impairment than the on-pump technique. Zamvar and
colleagues (p 1268) conducted a randomised controlled trial of 60 patients undergoing coronary artery bypass graft surgery for triple
vessel disease. They found that those assigned to the off-pump
technique were less likely to show major deterioration in scores for
neuropsychometric tests one week and 10 weeks after surgery.
