Almost three-quarters of all heart failure patients who are older than 65 have heart failure
with preserved ejection fraction (HFpEF). The proportion and hospitalization rate of patients …

THE left atrium (LA) serves three major roles that exert a profound effect on left ventricular
(LV) filling and overall cardiovascular performance. The LA is a contractile chamber that …

Background The authors hypothesized that in patients with heart failure with normal left
ventricular (LV) ejection fraction (HFNEF), the same fibrotic processes that affect the …

Objectives The aim of this study was to assess the effect of congestion and decongestive
therapy on left atrial (LA) mechanics and to determine the relationship between LA …

Changes in diastolic indexes during normal aging, including reduced early filling velocity
(E), lengthened E deceleration time (DT), augmented late filling (A), and prolonged …

Background Decreased function of the left atrium (LA) is a useful prognostic indicator in
dogs with myxomatous mitral valve disease (MMVD). In humans, LA strain is a novel severity …

Background Data regarding the contribution of left atrial (LA) dysfunction to the occurrence
of heart failure in patients with severe aortic stenosis (AS) are scarce. The aim of this study …

Aims To assess LA diastolic and systolic function and atrial dyssynchrony in patients with
heart failure with preserved ejection fraction (HFpEF) and to examine whether LA …

Background Left atrial reservoir strain (LARS) is a novel imaging biomarker of left ventricular
diastolic dysfunction. This study aimed to examine the prognostic implications of LARS in …

OBJECTIVES The objective of this study was to examine the hypothesis that a positive
inotropic agent improves left ventricular (LV) filling during left atrial (LA) contraction in the …
