Left ventricular pressure measurements. Box-and-whisker plots indicate median value, box at 25th/75th percentile, and whiskers are max/min values; dots represent values from individual animals. a Max P, maximum developed LV pressure; first derivative of LV pressure curve during systole (b) + dP/dt, and diastole (c) –dP/dt; (d) Tau, exponential decay time constant in diastole. Statistical analysis by one-way ANOVA with Tukey post hoc multi-group analysis; p-values between groups are indicated
