Incremental Prognostic Value of Ventricular-Arterial Coupling over Ejection Fraction in Patients with Maintenance Hemodialysis

摘要

Background: Left ventricular ejection fraction (LVEF) is a predictor of adverse outcomes in hemodialysis patients. LVEF is, however, an integral parameter determined by contractility, loading condition, and coupling. We sought to determine whether these components would better predict adverse outcomes and have incremental prognostic value over a validated clinical score and EF.
