Popis: | Background . Changes in memory and cognition frequently follow cardiac operations. We hypothesized that patients with the apolipoprotein E-ϵ4 allele are genetically predisposed to cognitive dysfunction after cardiac operations. Methods . The apolipoprotein E-ϵ4 allele was evaluated as a predictor variable for postoperative cognitive dysfunction in 65 patients undergoing cardiac bypass grafting at Duke University Medical Center. The primary outcome measure was performance on a cognitive battery administered preoperatively and at 6 weeks postoperatively. Results . In a multivariable logistic regression analysis including apolipoprotein E-ϵ4, preoperative score, age, and years of education, a significant association was found between apolipoprotein E-ϵ4 and change in cognitive test score in measures of short-term memory at 6 weeks postoperatively. Patients with lower educational levels were more likely to show a decline in cognitive function associated with the apolipoprotein E-ϵ4 allele. Conclusions . This study suggests that apolipoprotein E genotype is related to cognitive dysfunction after cardiopulmonary bypass. Cardiac surgical patients may be susceptible to deterioration after physiologic stress as a result of impaired genetically determined neuronal mechanisms of maintenance and repair. |
