Left Atrial Reservoir Function and Outcome in Heart Failure With Reduced Ejection Fraction The Importance of Atrial Strain by Speckle Tracking Echocardiography

摘要

BACKGROUND: Left atrial (LA) volume is a marker of cardiac remodeling and prognosis in heart failure (HF) with reduced ejection fraction (EF), but LA function is rarely measured or characterized. We investigated determinants and prognostic impact of LA reservoir function in patients with HF with reduced EF.
