Hemodynamic data. Hemodynamic data of Sham, MI and MI rats treated with açaí extract (100 mg/kg) during 4 weeks. The analyzed parameters were (A) left ventricular systolic pressure, (B) left ventricular end diastolic pressure, (C) -dP/dt and (D) + dP/dt. Values are mean ± S.E.M. *P < 0.05 vs. Sham. # P < 0.05 vs. MI. n = 6 per group.
