Absence of Cognitive Decline One Year After Coronary Bypass Surgery: Comparison to Nonsurgical and Healthy Controls

2011 ACCF/AHA Guideline for Coronary Artery Bypass Graft Surgery

“…884 Studies with appropriate comparison groups have demonstrated that most patients do not suffer cognitive decline after CABG. 885,886 For those who do, the postoperative cognitive changes are generally mild, and for most patients, they resolve within 3 months of surgery. 887 Long-term cognitive decline after CABG has been reported, 888,889 but other studies have shown that a similar degree of late cognitive decline occurs in comparison groups of demographically similar patients with CAD but without surgery, suggesting that the late decline is not related to the use of CPB.…”

Secondary Prevention After Coronary Artery Bypass Graft Surgery

“…375,376 Studies with appropriate comparison groups (including nonsurgical and healthy control subjects) have demonstrated that most patients do not suffer cognitive decline as a result of CABG. 377,378 For those who do, the postoperative cognitive changes are usually mild and generally resolve within 3 months of surgery. 379 Longterm cognitive decline after CABG has been reported, 380,381 but studies have shown that similar late cognitive decline occurs even among patients with CAD who do not undergo surgery, supporting that the decline is not related to the operation or the use of cardiopulmonary bypass.…”

Impacto do declínio cognitivo pós‐operatório na qualidade de vida: estudo prospectivo

“…33,39,40 Três meses após a cirurgia, uma melhoria significativa da qualidade de vida em pacientes sem DCPO foi demonstrada por um aumento em quase todos os escores dos domínios do SF-36; porém, entre os doentes com DCPO, nenhuma melhoria foi observada em qualquer dos escores do SF-36. Essa limitação na melhoria da qualidade também foi demonstrada em pacientes com DCPO por uma dependência mais significativa em P-ADL três meses após a cirurgia, em comparação com os pacientes sem DCPO.…”
