Key result
Coronary artery bypass graft surgery was associated with new MR abnormalities in 26.7% of patients at 1 week, all of whom exhibited significant postoperative neuropsychological deficits.
Why the study?
Is there a concordance between structural brain changes on magnetic resonance imaging and neuropsychological deficits after coronary artery bypass graft (CABG) surgery?
Population
15 patients (11 male, mean age 59 years) having coronary artery bypass graft (CABG) surgery.
Comparison

New MRI changes after CABG may flag neuropsychological deficits; leaves open causal link and needs prospective confirmation.
Observational (n=15)
Is there a concordance between structural brain changes on magnetic resonance imaging and neuropsychological deficits after coronary artery bypass graft (CABG) surgery?
Absolute Event Rate: 26.7% vs 93.3%
Preliminary data suggest a promising concordance between new structural brain changes on MRI and postoperative neuropsychological deficits in memory and attention after CABG surgery.
Toner et al. (1994) conducted an observational in Coronary artery bypass graft (CABG) surgery (n=15). Coronary artery bypass graft (CABG) surgery vs. Pre-surgery baseline was evaluated on New MR abnormalities and neuropsychological deficit. Coronary artery bypass graft surgery was associated with new MR abnormalities in 26.7% of patients at 1 week, all of whom exhibited significant postoperative neuropsychological deficits.
