Figure 4 Left ventricular (LV) remodeling and function were improved in rats with myocardial infarction (MI) given a caspase inhibitor (MI + CI, n = 12) for four weeks compared with vehicle (dimethyl sulfoxide) treated (MI + DMSO, n = 9) rats or MI rats without any pump (untreated MI, n = 15). Left ventricular remodeling still remained worse than in sham-operated animals (n = 17).
