EA/EES ratio and diastolic elastance emerged as reliable predictors of exercise capacity. In the wake of these results the authors suggested the clinical validation of a new index of “total …

Apr 10, 2020 · While Ees represents the cardiac contractility, Ea expresses all the extracardiac forces opposing to ventricular ejection or arterial load. Therefore, the interaction between the …

Left ventricular ejection fraction (LVEF) and ventricular-arterial coupling (VAC) [VAC = Ea/Ees; Ea: effective arterial elastance; Ees: left ventricle (LV) elastance] are both dimensionless ratios …

Sep 17, 2021 · Ventricular‐arterial coupling predicts outcomes in patients with heart failure. The arterial elastance to end‐systolic elastance ratio (Ea/Ees) is a noninvasively assessed index …

RV-pulmonary arterial coupling (Ees/Ea) has considerable reserve, from normal values of 1.5-2 to <0.8, and has the ability to detect pending RV failure in patients with pulmonary hypertension. …

Oct 24, 2024 · The Ea/Ees ratio is a key metric in assessing this coupling, with significant implications for cardiac performance, particularly in conditions like heart failure. Maintaining an …

Oct 2, 2021 · Right ventricular (RV) intrinsic contractility and its response to afterload defined as pulmonary arterial (PA) elastance, is referred to as RV-PA coupling. RV contractility can be …

Mar 12, 2019 · Traditionally, VAC is assessed by the non-invasive measurement of the ratio of arterial (Ea) to ventricular end-systolic elastance (Ees). With disease progression, both Ea and …

Jan 1, 2024 · The gold standard measurement, end-systolic elastance/arterial elastance ratio (Ees/Ea), is derived from invasive pressure-volume loop, which is technically demanding, …

Jan 8, 2019 · Ventricular contractility is well characterized by end-systolic elastance (Ees), a load-independent measure of systolic function. Arterial afterload, on the other hand, can be thought …
