Prediction of changes in left ventricular ejection fraction after off-pump coronary artery bypass grafting surgery by myocardial perfusion single-photon emission computed tomography

ABSTRACT

Introduction: Left ventricular ejection fraction [LVEF] is considered to be the single most important prognostic factor in patients with previous myocardial infarction. LVEF is not improved in all patients after coronary artery bypass grafting [CABG]. This study aimed to assess the possibility of prediction of LVEF changes after CABG using myocardial perfusion gated signle photon emission computed tomography [GSPECT]
