Mechano-energetics variables as functions of afterload. Work (A and B), total oxygen consumption (VO2; C and D) and total efficiency (ε Total ; E and F ) as functions of afterload for representative (A, C and E) STZ (filled circles) and SHAM (open circles) working hearts, and for the averages of n = 16 STZ or n = 17 SHAM working hearts (B, D and F). The variability of the relations in B, D and F is quantified in Figures 5 and 6 and Tables 2 and 3.
