Left atrial energy loss as a novel predictor of mortality and cardiovascular events in chronic kidney disease patients with preserved ejection fraction.

ABSTRACT:

Background

Patients with chronic kidney disease (CKD) have an increased risk of cardiovascular adverse events and abnormal intracardiac blood flow, which are commonly underestimated when evaluated by traditional echocardiographic parameters. Energy loss (EL), a novel Vector Flow Mapping (VFM) -based parameter, enables early hemodynamic assessment of cardiac dysfunction. This study sought to explore whether EL of left atrial has prognostic value for cardiovascular risk in CKD patients with preserved ejection fraction.

Methods

A total of 137 prospectively recruited patients with CKD in stages 3-5 and normal left ventricular ejection fraction (LVEF) (67% male, mean age 50.74 ± 13.23 years) underwent measurement of left atrial energy loss (LAEL) within three cardiac cycles, usin
