Why the study?
Does coronary artery bypass grafting affect cognitive performance in patients surviving the perioperative period without stroke?
Does coronary artery bypass grafting affect cognitive performance in patients surviving the perioperative period without stroke?
Long-term follow-up after CABG in patients without perioperative stroke shows no decline in cognitive performance, potentially aided by good vascular risk factor control.
Answers are grounded in this paper and cite their sources.
May support cognitive safety of CABG without perioperative stroke; leaves open confirmation in larger controlled studies.
The authors studied 52 of an initial cohort of 91 patients who underwent coronary artery bypass grafting and survived the perioperative period without stroke or other comorbidities, after a median follow-up of 55 months. Baseline data of the followed patients were comparable to those lost for follow-up. No patient showed a decline in neuropsychological test performance as compared to baseline. Vascular risk factor control was good in all patients, possibly contributing to the favorable outcome.
