Figure 2. The effects of treatment with 10 µM KB-R7943 or 10 µM MDL28170 on the recovery of heart function after the 3-min Ca²⁺ depletion treatment.

A. Representative left ventricular pressure tracing in the hearts subjected to the 3-min Ca²⁺ depletion treatment in the presence or absence of KB-R7943. B. Group results on the recovery of LVDP at the end of perfusion. C. Group results on LVEDP at the end of perfusion. Each bar represents the mean±SEM, n = 6. ^## P<0.01 vs. the control, **P<0.01 vs. with CaD3, ^† P<0.01 vs. MDL+CaD3. Please refer to Figure 1 for the abbreviations.
