Figure 1 Effects of long-term treatment with carvedilol (Carv), metoprolol (Met) and captopril (Cap) on collagen volume fraction in the noninfarcted area of the left ventricle (top) and the right ventricle (bottom) post-MI compared with untreated rats with MI taking vehicle (V) and sham-operated rats. Values are mean ± SE. *p < 0.05 versus untreated rats with MI. Rat groups are as in text. Numbers of animals in each group are as in Table 1.

Figure 2 Effects of long-term treatment with carvedilol (Carv), metoprolol (Met) and captopril (Cap) on hydroxyproline contents in the interventricular septum (top) and the right ventricle (bottom) post-MI compared with untreated rats with MI taking vehicle (V) and sham-operated rats. Values are mean ± SE. *p < 0.05 versus untreated rats with MI. Rat groups are as in text. Numbers of animals in each group are as in Table 1.
