Key result
Coronary artery bypass grafting is associated with short-term neuropsychological deficits similar to those seen in noncardiac surgery, though some cognitive deficits and depression may persist.
Why the study?
Does coronary artery bypass grafting cause specific short- and long-term neuropsychiatric consequences compared to noncardiac surgery?

Neuropsychological deficits after CABG are common but may not be specific to the procedure, as they are similarly seen in noncardiac surgery patients.
CABG neuropsychological deficits may not be procedure-specific; leaves open whether targeted prevention differs from noncardiac surgery.
This paper reviews findings regarding short- and long-term neuropsychiatric consequences of coronary artery bypass grafting (CABG) and noncardiac surgery. Stroke is one of the potentially most serious complications of CABG; studies have identified some demographic and medical risk factors. Short-term neuropsychological deficits are common after CABG, but have been similarly documented in noncardiac surgery patients, and may therefore not be specific to this procedure. Neuropsychological deficits in some cognitive areas may persist over time. Patients with depression before surgery are likely to have persistent depression afterwards. Also, depression does not account for the cognitive decline after CABG. Conflicting findings, and the possible methodological limitations of current published studies, are presented and discussed.

Reichenberg et al. (2007) conducted a review in Coronary artery bypass grafting and noncardiac surgery. Coronary artery bypass grafting (CABG) vs. Noncardiac surgery was evaluated on Short- and long-term neuropsychiatric consequences. Coronary artery bypass grafting is associated with short-term neuropsychological deficits similar to those seen in noncardiac surgery, though some cognitive deficits and depression may persist.
