ROSA, Marcelo Pereira da  and  PORTAL, Vera Lúcia. Carotid stenosis and coronary artery bypass grafting. Rev. Assoc. Med. Bras. [online]. 2011, vol.57, n.3, pp.323-327. ISSN 0104-4230.

OBJECTIVE: To identify carotid stenosis (CS) prevalence and potential mortality predictors in individuals undergoing elective coronary artery bypass grafting (CABG). METHODS: Cohort study including 393 scheduled for CABG. All patients underwent a color Doppler ultrasound study of the carotid arteries prior to CABG and were assessed for morbidity and mortality over the hospitalization. CS was considered clinically relevant when if > 50%. Significance was set at p < 0.05. Logistic regression was used to define mortality independent predictors. RESULTS: CS prevalence was 17.4%. Following logistic regression analysis, CS > 50% (p = 0.001) and chronic renal failure (CRF) (p = 0.03) remained as mortality independent predictors. CONCLUSION: CS showed a high prevalence in the study sample and together with CRF was a mortality independent factor.
