In the present study, the relation between improvement in the left ventricular ejection fraction (LVEF) and heart failure symptoms was evaluated in 100 patients with ischemic cardiomyopathy undergoing coronary revascularization. In patients with viable myocardium, the improvement in the LVEF after revascularization was accompanied by improvement in heart failure symptoms in most patients (80%); most viable patients (75%) without improvement in LVEF also showed an improvement in New York Heart Association functional class. Conversely, most nonviable patients failed to improve in LVEF or New York Heart Association class.
在本研究中，对100例接受冠状动脉血运重建的缺血性心肌病患者评估了左心室射血分数（LVEF）改善与心力衰竭症状之间的关系。在有存活心肌的患者中，血运重建后LVEF的改善在大多数患者（80%）中伴随着心力衰竭症状的改善；大多数LVEF无改善的存活患者（75%）纽约心脏协会功能分级也有改善。相反，大多数无存活心肌的患者LVEF或纽约心脏协会分级未能改善。
