简要总结
Single or repeated application of autologous bone marrow-derived stem cells to treat chronic post-infarction heart failure
详细描述
Improve mortality and morbidity in patients with symptomatic chronic post-infarction heart failure under full dose conventional medical and device treatment including resynchronization therapy, by single versus repeated intracoronary infusion of autologous bone marrow-derived mononuclear cells.

结局指标
主要结局
Mortality at 2 years after inclusion into the study
时间窗: 2 years
2-year observed mortality is significantly lower in patients receiving 2 repeated intracoronary applications of autologous bone marrow-derived cells (t2c001) compared to patients receiving 1 intracoronary application of autologous bone marrow-derived cells (t2c001)
次要结局
- Morbidity at 2 and 5 years after inclusion into the study(2 years and 5 years)
