Polydatin attenuates diabetes-induced left ventricular dysfunction. Echocardiography was performed on control or diabetic rats treated with either polydatin (90 mg/kg/day) or vehicle for 8 weeks. Panel (a) Left ventricular end diastolic diameter (LVEDD); (b) Left ventricular posterior wall thickness (LVPWD); (c) The ratio of E/A; (d) Left ventricular shortening fraction (LVFS); (e) Left ventricular ejection fraction (LVEF). Data were expressed as means ± SEM (n = 7). *P < 0.05, **P < 0.01 versus Con; #P < 0.05, ##P < 0.01versus DM
