Figure 1. Schematic of group-averaged end-systolic pressure–volume relationship (ESPVR), where ESP=Ees(ESV−V0) (V0 is volume intercept). Figure 1. Schematic of group-averaged end-systolic pressure–volume relationship (ESPVR), where ESP=Ees(ESV−V0) (V0 is volume intercept). Solid lines represent the mean ESPVR; dotted lines, 95% CI for each group. For comparison of Ees (slope) between groups, *P<0.05 vs CON. Carolyn S.P. Lam et al.
