title: [Cognitive functions in elderly high-risk patients after off-pump coronary artery bypass grafting versus conventional bypass grafting - a randomised study - Secondary publication].
abstract: It has been suggested that the risk of cerebral dysfunction is less with off-pump coronary artery bypass grafting (OPCAB) than with conventional coronary artery bypass grafting (CCAB). The study is a part of the Best Bypass Surgery Trial. A total of 120 elderly patients underwent psychometric testing with a neuropsychological test battery before as well as 3 months after surgery. Cognitive dysfunction was identified in 7.4% of the patients in the OPCAB group and 9.8% in the CCAB group. We found no significant difference after either OPCAB or CCAB.
