(A) Schematic overview of experimental procedure of Langendorff model. (B) Serial injections of buffer, dobutamine, and IPA with intermittent washing steps in the Langendorff mouse model show dose-depended effects of IPA on left ventricle developed pressure (LVdp). Dobutamine (1 mg/ml, 1:256) was administered as positive control. (C) Percentage difference of LVdp in relation to baseline/wash between buffer, IPA, and wash. All data were shown as mean ± SD with N = 7/group. *p < 0.05, **p < 0.01, and ***p < 0.001 by 1-way ANOVA.
