  1. E es (Emax), end-systolic elastance (slope of the end-systolic relationship); Preload recruitable stroke work; dP/dt max: Maximum rate of LV pressure change during systole; dP/dt min: Minimum rate of LV pressure change during systole; EDPVR: End diastolic pressure volume relationship. Continuous data are presented as mean with 95% confidential intervals (95% CI) or as median with interquartile ranges (IQR 25-75).
