Brief Summary:
The aim of our prospective randomised study is to assess the efficacy of the retrograde application of non-selected bone marrow autologous cells concentrate (BMAC) in patients with heart failure with reduced ejection fraction of left ventricle (HFREF) of ischemic aetiology. The evaluated preparation is concentrated BMAC, obtained using Harvest SmartPReP2 technology.

Condition or disease Intervention/treatment Phase
Heart Failure Drug: BMAC Phase 2

Detailed Description:

Our assumption is that non-selected BMAC administrations will lead to improvements in the left ventricular ejection fraction (LV EF), the left ventricular end-systolic and end-diastolic diameters and volumes (measured with magnetic resonance imaging) compared to standard heart failure therapy.

Furthermore, it will be associated with improved exercise tolerance in the six-minute corridor walk test and an improvement in the life quality of patients without increasing the incidence of severe ventricular arrythmias.
