Poststress left ventricular ejection fraction is an independent predictor of major cardiac events in patients with coronary artery disease and impaired left ventricular function
Aim. The aim of this study was to investigate the prognostic value of myocardial perfusion and function SPECT imaging in patients with coronary artery disease (CAD) and poor left ventricular (LV) function. Methods. We studied 261 patients (231 men, age 66 10 years) with CAD and a resting IV ejection fraction (LVEF) Results. During a median follow-up of 31 months, 52 patients (20%) died (35 cardiac deaths), 50 (19%) developed a MACE and 69 (20%) a MACE-HF. In a clinical model, diabetes and angina status were the only predictors of MACE (chi(2) = 19.3; P
