IVST (mm)	0.62 ± 0.06	0.59 ± 0.06
LVPWT (mm)	0.62 ± 0.16	0.51 ± 0.10*
LVIDd (mm)	3.99 ± 0.24	5.10 ± 0.38**

The echocardiographic parameters of 3-month old male αMHC/miR-143/145TG (L9) mice are shown. Unpaired t-tests were used (n = 8 ~ 9. *p < 0.05 vs. NTG, **p < 0.01 vs. NTG). The data are presented as the means ± standard deviation (SD). BW: body weight, HW: heart weight, IVST: interventricular septal thickness, LVPWT: left ventricular posterior wall thickness, LVIDd: left ventricular internal dimension at diastole, LVIDs: left ventricular internal dimension at systole, %LVFS: percentage of left ventricular fractional shortening.
