Relationship between left ventricular end-systolic elastance (Ees) and standard left ventricular ejection fraction (LVEF) calculation, Ea-adjusted LVEF and peripheral Ea-adjusted LVEF. Linear regression analysis for left ventricular end-systolic elastance (Ees) and standard LVEF, LVEF corrected to effective arterial elastance (Ea = left ventricular end-systolic pressure/left ventricular stroke volume) and peripheral Ea-adjusted LVEF (Eaperiph = radial mean arterial pressure/stroke volume). Colors inside circles represent different interventions: red, afterload; green: preload; blue: contractility
