Neurocognitive Outcomes 3 Years After Coronary Artery Bypass Graft Surgery: A Controlled Study

We found a mild but nonsignificant trend toward late postoperative cognitive decline for all study groups with coronary artery disease, but no significant differences in the degree of late postoperative cognitive decline after on-pump compared with off-pump surgery. These findings suggest that previously reported late decline after bypass surgery is not specific to use of cardiopulmonary bypass.
