Popis: Background Transthoracic echocardiography (TTE) is the most commonly used method for measuring left ventricular ejection fraction (LVEF), but its reproducibility remains a matter of controversy. Speckle tracking echocardiography assesses myocardial deformation and left ventricular systolic function by measuring global longitudinal strain (GLS), which is more reproducible, but is not used routinely in hospital practice. Aim To investigate the feasibility of on-line two-dimensional GLS in predicting LVEF during routine echocardiographic practice. Methods The analysis involved 507 unselected consecutive patients undergoing TTE between August 2012 and November 2013. Echocardiograms were performed by a single sonographer. Echogenicity was noted as good, moderate or poor. Simple linear regression was used to assess the relationship between LVEF and GLS, overall and according to quality of echogenicity. Receiver operating curve (ROC) analysis was used to identify the threshold GLS that predicts LVEF ≤ 40%. Results Mean LVEF was 64 ± 11% and GLS was –18.0 ± 4.0%. A reasonable correlation was found between LVEF and GLS (r = –0.53; P
