Data presented as means (SD).
LVSP and LVEDP = left ventricular end-systolic and end-diastolic pressure, respectively; +dP/dt and −dP/dt = maximal rate of pressure development and decline, respectively;
P ≤ 0.05,
P ≤ 0.01 vs. MI rats;
P ≤ 0.05,
P ≤ 0.01 vs. Sham operated rats; ANOVA with Student-Newman-Keuls’ Multiple Comparison Test.
