(A) Echocardiographically determined left ventricular (LV) fractional shortening (FS) during the time course of experiment. (B) Invasively determined index of LV contractility (index dP/dtmax) at the end of the experiment. Statistical significance in comparison with ‘*’ the initial values within each group (paired t-test, P<0.05), ‘c’ control, ‘d’ daunorubicin and ‘x’ DEX+DAU groups (ANOVA, P<0.05).
