研究人员注意到：负荷总分和左心室增大程度可以提供更加准确的预后信息，但是射血分数对本模型没有贡献。
Summed stress scores and left ventricular enlargement provided incremental prognostic information, the researchers note, but including left ventricular ejection fraction did not improve the model.
目的研究冠状动脉旁路移植术(CABG)前左心室射血分数(EF)和左心室缩短分数(FS)对术后室性心律失常(VA)预测的准确性。
Objective To evaluate the accuracy of left ventricular ejection fraction (ef) and fractional shortening (FS) for predicting ventricular arrhythmias (va) after coronary artery bypass grafting (CABG).
