Postoperative cognitive dysfunction, frequent in cardiac surgeries, leads to major consequences. The physiopathological processes involved in this condition are still not completely elucidated, though its multifactor character is known. Besides pre-operative factors such as age and education, some intra-operative factors are of extreme importance. However, according to a vast literature on the subject, these factors are not sufficient to totality clarify the etiology of all cases, thus suggesting a genetic basis for this neurological sequel. In this review article, we briefly assess the factors involved in this cognitive dysfunction and discuss pharmacotherapy in the prevention of this event.Descriptors: Coronary artery bypass surgery.

ResumoDisfunção cognitiva pós-operatória é situação freqüente em cirurgias cardíacas, o que pode levar a conseqüências imensuráveis para os indivíduos acometidos. Os processos fisiopatológicos envolvidos nessa condição ainda não se encontram totalmente elucidados, apresentando um caráter multifatorial. Além de fatores pré-operatórios, como idade e escolaridade, alguns fatores intra-operatórios também são de extrema importância. Entretanto, conforme ampla literatura sobre o tema, esses fatores não são capazes de esclarecer etiologicamente a totalidade dos casos, remetendo a uma base genética para essa seqüela neurológica. Nessa revisão, avaliamos fatores envolvidos na disfunção cognitiva e a terapia farmacoprotetora empregada em sua prevenção.Descritores: Revascularização miocárdica. Circulação extracorpórea.
