Prognostic implications of ventricular strain in heart failure with preserved ejection fraction: a 2D speckle-tracking echocardiography study
Two-dimensional speckle-tracking echocardiography (2D-STE) has been widely used to assess subclinical myocardial dysfunction, primarily focusing on left ventricular (LV) longitudinal systolic function in heart failure with preserved ejection fraction (HFpEF). However, data remains limited on the prognostic value...
