Overview

LA strain by STE may better estimate filling pressures than E/Em in advanced HF; hypothesis-generating, needs prospective validation.

Key Points

  • To evaluate the diagnostic accuracy of left atrial longitudinal deformation assessed by speckle tracking echocardiography compared to standard E/Em ratio for estimating left ventricular filling pressures in advanced systolic heart failure.
  • Evaluated patients with advanced systolic heart failure undergoing diagnostic cardiac assessments.
  • Measured left atrial longitudinal strain via speckle tracking echocardiography (STE) alongside conventional E/Em ratios.
  • Compared echocardiographic parameters directly against invasively measured pulmonary capillary wedge pressure (PCWP).
  • Standard E/Em ratio correlated poorly with invasively measured left ventricular filling pressures in advanced systolic heart failure.
  • Left atrial longitudinal strain measured by STE correlated well with PCWP, providing superior noninvasive estimation of filling pressures.
