Brief summary
Phase I-II Clinical Trial-Safety and efficacy of umbilical cord derived mesenchymal stem cells (UC-MSCs) in patients with chronic heart ischemia cohort and perspective study.
Detailed description
Phase I-II Clinical Trial-Safety and efficacy of umbilical-cord-derived mesenchymal stem cell (UC-MSC) in patients with chronic heart ischemia cohort and prospective study. Forty patients will be selected and divided into two groups according to patients' willingness to stem cell treatment. The patients who are willing to receive stem cell transplantation will receive UC-MSCs by coronary injection. The patients in control group will not receive any intervention. Every patient will maintain their standard treatment of chronic heart ischemia, with maximum tolerated dosage without side effects. The day of infusion will be considered day zero. From that moment, followup will be divided into 0-1,1-3, 3-6, and 6-12 months. Clinical results will be analyzed after completion of 12 months of followup.
Interventions
Human umbilical cord MSCs are transplanted by intracoronary infusion(1×10\^7)

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Number and nature of adverse events | Within the first year after intracoronary infusion | Evidence for new clinical/biological abnormalities. |
| Incidence of major adverse coronary events (MACE) | Within the first year after intracoronary infusion | Major adverse coronary events (MACE) were defined as cardiac death, non-fatal myocardial infarction, or rehospitalization for acute coronary syndrome and for congestive heart failure. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Exercise Time and Level | Post cell transplantation: 1, 3, 6, 12 months | Exercise time and level as assessed via six minute walk test. |
| Quantify myocardium perfusion measured by SPECT | Post cell transplantation: 6, 12 months | The efficacy of UC-MSC treatment was quantified by the differences between the two groups and from baseline to 6 and 12 months in perfusion images, as measured by SPECT. |
| Assessment of heart function by left ventricular ejection fraction | Post cell transplantation: 1, 3, 6,12 months | Change in left ventricular ejection fraction was assessed with echocardiography after cell implantation. |
| Clinical Improvement in NYHA Classification | 1 year | The NYHA scale ranges from 1 (best)Mild- no limitation of physical activity due to heart failure to 4 (worst) Severe-Unable to carry out any physical activity without discomfort due to heart failure. |
