This study is an exploratory clinical study to observe the safety and efficacy of the Intravenous Infusion of Umbilical Cord Mesenchymal Stem Cells in the heart failure patients with reduced ejection fraction. The study was a 12 months single center, randomized, double-blind, placebo-controlled trial that included 12 weeks of treatment, and 9 months of follow-up.


The study was a 12-month single center, randomized, double-blind, placebo-controlled trial that included 12 weeks of treatment, and 9 months of follow-up.We plan to recruit 40 subjectswhich were divided into experimental group and control group. The volunteers of the experimental group will be given peripheral intravenously infusion a dose of 1.0*10^6/kg human umbilical cord mesenchymal stem cell (HUC-MSC) respectively at 0,6,12 week. The control group will be given the same dose of 1 percent human serum albumin injection. Then centralization visit was conducted at 0,7 day, 6,12 week, 6 and 12 month. The primary end points include cardiac function improvement and adverse events.
