Table 2. Left ventricular function in vitro evaluated by isolated heart study. C: control group; A: açai group; D: doxorubicin group; DA: doxorubicin + açai group; V₀: initial balloon volume; +dP/dt: maximum left ventricular pressure development rate; -dP/dt: maximum left ventricular pressure decrease rate; SP_max: maximum systolic pressure. Values are expressed as the mean ± standard deviation; p value: two-way ANOVA; pi: p value for doxorubicin vs acai interaction; ^#variable was normalized to statistical analysis
