Values are means ± SEM. Anaemia represents in utero anaemia. LVSP, left ventricle systolic pressure, dP/dtmax and dP/dtmin, maximum and minimum derivative of pressure with respect to time respectively. No differences were observed at baseline, the end of ischaemia and during the 2-h reperfusion in each group (one-way anova), or between groups (repeated measures).
Not significant by anova but P < 0.05, compared to the control by unpaired t-test.
