Feasibility of assessing cardiac systolic function using longitudinal fractional shortening calculated by two-dimensional speckle tracking echocardiography.


BACKGROUND The left ventricular longitudinal fractional shortening (LVLFS) evaluated by the speckle tracking method reflects the longitudinal contraction of left ventricle (LV). We aimed to evaluate the accuracy of LVLFS as an index of LV systolic function. METHODS Two hundred thirty-three patients with or without heart failure (HF) were divided into four… (More)
