Outcome Measures

Primary Outcomes (1)

  • compare the 12 month change in left ventricular mass

    The primary analysis to compare the 12 month change in left ventricular mass between the two treatment arms will be performed by a one-sided two-sample t test at a significance level of 0.025.

    12 month

Secondary Outcomes (6)

  • Change in Quality of Life

    baseline, 12 month

  • safety of EGCG

    12 month

  • change in cardiac biomarkers

    Baseline, 12 Month

  • improvement of hematological remission

    Baseline, 12 Month

  • Organ response in affected organs other than heart

    Baseline, 12 Month

  • +1 more secondary outcomes
