Primary Outcome Measures

Name	Time	Method
Main Objective: To perform at clinical double-blind placebo-controlled CSCC_ASC<br>multicentre study in heart failure patients to investigate the<br>regenerative capacity of the CSCC_ASC treatment.;Secondary Objective: Improvement in cardiac function and clinical symptoms;Primary end point(s): The primary endpoint is change in left ventricle end-systolic volume<br>(LVESV) at 6 months follow-up between CSCC_ASC and placebo patients;Timepoint(s) of evaluation of this end point: 6 months after treatment
