Data presented as means (SD).

N = number of animals; Body Wt1 =  body weight before surgery; Body wt2  =  body weight at terminal study; Heart Wt  =  heart weight; HW/BWt2 ratio  =  Heart Wt/Body wt2 ratio; LV Wt  =  left ventricular weight; *, p<0.05, **, p<0.01 vs. Sham operated rats; †, p<0.05 vs. MI; ANOVA with Bonferroni's Multiple Comparison Test.
