| Abstract: | 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. |
