Assessment of ventricular remodeling by echocardiography (A) and LVW/BW ratio. A. Echocardiographic parameters at 1, 3, and 5 weeks after MI (n = 5) and sham groups (n = 5) under isoflurane anesthesia. A progressive increase in LVPWd was seen in MI group compared with sham, but there were no significant differences in LVIDd, %FS, or %Vcf between the two groups. * p < 0.05 vs. sham, # p < 0.05 vs. baseline. MI: myocardial infarction, SH: sham. B. LVW/BW ratio (mg/g) was significantly higher in MI group (n = 5) than in sham group (n = 5) (MI: 5.11 ± 0.32, sham 3.60 ± 0.35; p < 0.05), supporting the echocardiographic finding of LV hypertrophy in MI group. * p < 0.05 vs. sham.
