Aims: Load dependence is an important source of variation in left ventricular (LV) deformation. This impacts on the precision of information obtained from serial measurements. However, it is clinically important to distinguish actual myocardial dysfunction from changes associated with altered loading conditions. We sought to investigate the association of changes of loading parameters with changes in LV longitudinal (GLS) and circumferential (GCS) strains. Methods and results: Baseline and a 12-month follow-up 2D echocardiograms were performed in 191 Stage A heart failure patients with uncomplicated hypertension. These patients underwent simultaneous measurement of conventional and central b..
