Data presented as means (SD).
N, total number of rats (both preps); Body Wt1, body weight before surgery; Body wt2, body weight at terminal study. Heart Wt, heart weight; Hw/BWt2, heart wt-to-body wt2 ratio; *, p < 0.05, **, p < 0.01 vs. Sham rats; ‡, p < 0.01 vs. MI rats; ANOVA with Student-Newman-Keuls’ or Dunnett T3’s (Heart Wt and Hw/BWt2) Multiple Comparison Test.
