左心功能衰竭患者冠状动脉搭桥术后早期效果的预测

Predictors of early outcome after coronary artery bypass in patients with left ventricular failure

目的探讨心功能衰竭患者行冠状动脉搭桥术后生存率的预测指标。方法研究334例连续实施单纯搭桥术患者资料。将患者分为正常组(n=283,左心室射血分数≥40%)和心功能衰竭组(n=51,左心室射血分数<40%)。两组进行对比分析。结果多因素分析显示,LESVI是惟一独立存在的依据左室功能评估生存率的指标量(P<0.001)。结论LVESVI是预测心功能衰竭患者搭桥术后生存率的最重要指标。

Objective To explore the prognostic factors in patients with severe myocardial dysfunction. Methods We investigated the data of 334 consecutive patients who underwent isolated coronary artery bypass grafting （CABG）. The patients were divided into normal cardiac function group（n=283, left ventricular ejection fraction ≥40%） and the left ventricular failure group （n=51, left ventricular ejection fraction〈40%）.Results On multivariate analysis, LVESVI was the only independent left ventricular function parameter that can predict survival （P〈0.001）. Conclusion LVESVI is the most important predictor of survival after coronary artery bypass surgery in patients with severe myocardial dysfunction.
