Values are mean ± S.E. LVPWd, left ventricular posterior wall thickness at diastole; LVPWs, left ventricular posterior wall thickness at systolic; IVSd, Interventricular septum at diastolic; IVSs, Interventricular septum at systolic. *p < 0.05, **p < 0.01 siginificant difference vs MYC. #p < 0.05, ##p < 0.01 significant differentce from MOC.
