In this study, 63% of patients with a substantial amount of viable myocardium showed an increased left ventricular ejection fraction (LVEF) 12 ± 3 months after coronary artery bypass grafting. In 93% of these patients, increased LVEF persisted at 4.5 ± 1 years of follow-up. Conversely, in nonviable patients, LVEF did not increase at 12 ± 3 months or at follow-up of 4.5 ± 1 years.
