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).
The changes of cardiac function, renal function, echocardiographic left ventricular ejection fraction(LVEF), left ventricular fractionshortening(LVFS) before and after treatment were compared.
