Design:
This was a prospective, descriptive study.
Setting:
The study took place in cardiovascular units at a large urban metropolitan, midwestern tertiary care hospital.
Sample:
Fifty-four patients undergoing off-pump coronary artery bypass surgery were included.
Outcome Measures:
Outcome measures were neurocognition preoperatively at baseline (within 72 hours of surgery) and postoperatively (at least 72 hours after surgery but before discharge).
Results:
In neurocognitive tests of cognition (memory, language, and attention) there was an improvement in the cognitive composite from the preoperative baseline to the postoperative follow-up (P < .001). However, in tests of motor function (motor speed and information processing speed) there was a decline in the motor composite (P = .006).
Conclusions:
After off-pump coronary artery bypass surgery, patients had an overall improvement in tests of memory, language, and attention (cognitive composite), but a decline in tests of motor speed and information processing speed (motor composite).
