**Figure 5.** **Hemodynamics assessment of left ventricular function.** (**A**) Representative recordings of left ventricular (LV) pressure and pressure change rate (dp/dt). (**B**) LV systolic pressure. (**C**) LV end-diastolic pressure. (**D**) Maximum increasing rate of LV pressure (dp/dt max). (**E**) Maximum descending rate of the LV pressure (dp/dt min). (**F**) LV contractility index (dp/dt max divided by the pressure at the time of dp/dt max). (**G**) Exponential time constant of relaxation (Tau). ^{*}*P* < 0.05 compared with the sham group. ^{#}*P* < 0.05 compared with the prior time point in the MI group. *n* = 6–10 at various time point.
