Brief summary

Single or repeated application of autologous bone marrow-derived stem cells to treat chronic post-infarction heart failure

Detailed description

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.

Design outcomes

Primary

MeasureTime frameDescription
Mortality at 2 years after inclusion into the study2 years2-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)

Secondary

MeasureTime frameDescription
Morbidity at 2 and 5 years after inclusion into the study2 years and 5 yearsEfficacy endpoints: Comparison between the 2 treatment groups at 2-year and 5-year follow-up * Cardiac mortality, cardiovascular mortality * Rehospitalisation for heart failure * Ischemic cardiac events (STEMI, NSTEMI, ACS) * Coronary revascularisations (PCI / CABG) * Heart transplantation, Assist-device implantation * New resynchronization therapy, ICD implantation * NYHA-Status, NT-proBNP serum levels * Minnesota Living with Heart Failure Questionnaire Safety endpoints: bleeding events, all in-hospital events (during hospitalization for BMC therapy), life-threatening arrhythmias, new malignancies
