RVDD: right ventricular diastolic diameter; LVEDD = left ventricular end diastolic diameter; LVESD = left ventricular end sistolic diameter; IVS = interventricular septum at end diastole; LVT: diastolic left ventricular posterior wall thickness; LA: diastolic diameter of the left atrium; EJ: ejection fraction; LVMI: left ventricular mass index. *means p< 0.05 as compared with C (Control), I (Phase I) or II (Phase II) using ANOVA followed by Bonferroni post test.
