Concentric LV remodeling explains why E/e′ is a reliable estimate of left atrial pressure in heart failure with normal LV ejection fraction. In a concentrically remodeled LV, .The Ea/Ees ratio, owing to its mathematical more dynamic behaviour, can be more sensitive than LVEF, being a valuable clinical tool in patients with heart failure (HF) with reduced EF, acute . Concentric LV remodeling explains why E/e′ is a reliable estimate of left atrial pressure in heart failure with normal LV ejection fraction. In a concentrically remodeled LV, early diastolic myocardial lengthening loads are low because of small LV cavity size and thick LV walls.The Ea/Ees ratio, owing to its mathematical more dynamic behaviour, can be more sensitive than LVEF, being a valuable clinical tool in patients with heart failure (HF) with reduced EF, acute unstable haemodynamic situations, where Ees and Ea variations are disproportionate.
As an index of LV afterload, the effective arterial elastance (LV-Ea) was calculated using the quotient of LV end-systolic pressure (ESP) and LV-SV from baseline measurements. Ventriculo-arterial coupling was assessed as Ees/Ea.
Current Doppler echocardiography guidelines recommend using early to late diastolic transmitral flow velocity (E/A) to assess diastolic function, and E to early diastolic mitral annular tissue velocity (E/e') to estimate LV filling pressures.Oct 2020 - Present 4 years 1 month.

This analysis shows that both a surrogate of left ventricular delay (Q∗LV) as well as interventricular delay (RV-LV) can be measured from the same intracardiac electrograms. This demonstrates the potential for automation of these measures in CRT devices.
There are several processes that cause acute left ventricular (LV) systolic heart failure including arrhythmias, valvular disease, acute coronary syndrome, progression of chronic heart failure, and myocarditis. Current Doppler echocardiography guidelines recommend using early to late diastolic transmitral flow velocity (E/A) to assess diastolic function, and E to early diastolic mitral annular tissue velocity (E/e') to estimate LV filling pressures.Objective: Effective arterial elastance (Ea), integrating the pulsatile component of left ventricular (LV) afterload, is an estimate of aortic input impedance. We evaluated relationships of Ea with left ventricular anatomy and function in essential hypertension.
Stroke work (SW) is the area within the LV pressure-volume loop for one cardiac cycle, while the potential energy (PE) is the area sub served by the Ea and LV end-systolic volume (ESV).
