Am: peak velocities of left ventricular myocardium at late diastole; Day 0: Before initiation of medication; Day 7: 7 days after the initiation of medication; Day 28: 28 days after the initiation of medication; Day 56: 56 days after the initiation of medication; Day 84: 84 days after the initiation of medication; Em: peak velocities of left ventricular myocardium at early diastole; IVS: interventricular septal; LVFW, left ventricular free wall; Sm: peak velocities of left ventricular myocardium at systole. Data are expressed as medians (range). * and ** Indicate significant difference compared to Day 0 values at P<0.05 and P<0.01, respectively.
