Summary of cardiac hemodynamic data.

Data are means±1SD (n = 8 per group); CO, coronary occlusion; REP, reperfusion. HR: heart rate (beats/min); LVPS (mmHg): LV systolic pressure; MAP (mmHg): mean arterial pressure; RPP (beats/min X mmHg/1000): rate-pressure product; LV dP/dt+, dP/dt− (mmHg/s): index of LV function during ventricular contraction, relaxation; p value using ANOVA with degree of freedom, df: 15,111. Multiple comparisons between experimental groups and within interventions were performed using ANOVA with the Student’s-Newman-Keuls multiple range test; means with similar letters are not statistically different.
