XXXX and driving performance after coronary artery bypass surgery.

@entity1 @entity73 @entity149
OBJECTIVE: @entity149 is common after cardiac surgery but few studies have examined the relationship between postoperative neuropsychological test performance and everyday behavior. The influence of postoperative @entity73 on car driving has previously not been investigated. The purpose of this study was to evaluate neurocognitive function and driving performance after coronary artery bypass grafting (CABG). METHODS: Twenty-seven @entity1 who underwent coronary artery bypass grafting with standard cardiopulmonary bypass technique and 20 @entity1 scheduled for percutaneous coronary intervention (PCI) under local anesthesia (control group) were enrolled in this prospective study conducted from April 1999 to September 2000. Complete data were obtained in 23 and 19 @entity1 , respectively. The @entity1 underwent neuropsychological examination with a test battery including 12 tests, a standardized on-road driving test and a test in an advanced driving simulator before and 4-6 weeks after intervention. RESULTS: More @entity1 in the coronary artery bypass grafting group (n=11, 48%) than in the percutaneous coronary intervention group (n=2, 10%) showed a @entity73 after intervention (P=0.01). In the on-road driving test, @entity1 who underwent coronary artery bypass grafting deteriorated after surgery in the cognitive demanding parts like traffic behavior (P=0.01) and attention (P=0.04). @entity1 who underwent percutaneous intervention deteriorated in maneuvering of the vehicle (P=0.04). No deterioration was detected in the simulator in any of the groups after intervention. @entity1 with a @entity73 after intervention also tended to drop in the on-road driving scores to a larger extent than did @entity1 without a @entity73 . CONCLUSION: This study indicates that cognitive functions important for safe driving may be influenced after cardiac surgery.
