Brief Summary

Coronary artery bypass surgery is associated with postoperative cognitive decline, which has largely been attributed to the use of the heart lung machine. We hypothesized that long-term cognitive outcome may improve by avoiding the heart lung machine. The objective of the present study is to compare the effect of coronary bypass surgery with and without heart lung machine on cognitive and clinical outcome, five years after surgery.
