LVDD, mm	5.59 ± 0.32	6.44 ± 0.16	6.07 ± 0.11
STh, mm	1.52 ± 0.03*	1.85 ± 0.03*	1.71 ± 0.02*
LVPWTh, mm	1.55 ± 0.02*	1.92 ± 0.06*	1.70 ± 0.03*
ES, %	60.76 ± 0.89	60.87 ± 0.46	61.39 ± 1.34
MVS, %	30.60 ± 1.51	30.53 ± 0.96	30.66 ± 0.77
LVMI
mg/g	1.39 ± 0.09*	2.61 ± 0.12*	2.04 ± 0.05*
mg/mm	12.79 ± 1.05*	21.43 ± 1.15*	17.81 ± 0.39*

Values are means ± SE; n, no. of rats. SHR, spontaneously hypertensive rats; LVDD, left ventricular diastolic diameter; STh, septum thickness; LVPWTh, left ventricular posterior wall thickness; ES, endocardial shortening; MVS, midwall ventricular shortening; LVMI, left ventricular mass index.

^*P < 0.05 vs. all others groups.
