Non-invasive evaluation of end systolic left ventricular elastane according to pressure-volume curve modelling during ejection in arterial hypertension

Objective: Non invasive methods have been proposed to assess end systolic left ventricular (LV) elastance (Ees), but clinical application remains complex. The aim of the present study was to 1) estimate Ees according to modeling of LV pressure-volume (P-V) curve during ejection and validate our method with existing published LV P-V loop data 2) test clinical applicability to detect a difference in Ees between normotensive and hypertensive subjects.
