摘要

Moderate to severe impairment in Left ventricular ejection fraction (LVEF) has been shown to predict major adverse cardiac events (MACE). However LVEF is an estimate of LV contractility and does not provide information about regional wall abnormalities or the presence of myocardial scar. Recently
