To identify carotid stenosis (CS) prevalence and potential mortality predictors in individuals undergoing elective coronary artery bypass grafting (CABG).
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.
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.
CS showed a high prevalence in the study sample and together with CRF was a mortality independent factor.
确定择期冠状动脉旁路移植术（CABG）患者的颈动脉狭窄（CS）患病率及潜在的死亡预测因素。
队列研究纳入393例计划行CABG的患者。所有患者在CABG术前均接受颈动脉彩色多普勒超声检查，并在住院期间评估其发病率和死亡率。当CS>50%时被认为具有临床相关性。显著性设定为p<0.05。采用逻辑回归确定独立的死亡预测因素。
CS患病率为17.4%。经过逻辑回归分析，CS>50%（p=0.001）和慢性肾衰竭（CRF）（p=0.03）仍是独立的死亡预测因素。
CS在研究样本中患病率较高，且与CRF共同构成独立的死亡因素。
