Figure 4 The peak early diastolic left ventricular (LV) filling rate (E) and peak lengthening rate of the LV anteroposterior dimension (EAP) and septolateral dimension (ESL) were closely related to the peak early diastolic left atrial (LA) to LV pressure gradient during the development of heart failure (HF). In contrast, the peak long-axis lengthening rate (EM) progressively declined, despite the increase in the LA to LV pressure gradient during the development of HF.
