Clinical Trial Summary

This study will evaluate the efficacy and safety of "Therapeutic Use of Autologous-Primed Autologous Peripheral Blood Stem Cell Treatment for Myocardial Regeneration in Acute Myocardial Infarction".

Description:

Patients diagnosed with acute myocardial infarction will receive percutaneous coronary intervention to the culprit coronary artery according to standard procedures. For peripheral blood stem cell mobilization, Granulocyte colony-stimulating factor (G-CSF) and erythropoietin (EPO) will be injected for a total of 4 days, followed by collection of mobilized peripheral blood stem cell (mobPBSC) via apheresis. In ex-vivo setting, mobPBSC will be primed with angiopoietin 1 (Ang1) for 1 hour. A total of 2 X109 Ang1 primed mobPBSC will be injected to the culprit artery.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Left ventricular systolic function	Left ventricular ejection fraction measured by echocardiography (measured in percent)	12 months after treatment
Secondary	Regional wall motion score index	Regional wall motion score index measured by echocardiography. The score is scaled from 1.0 to 4.0. Using a standard transthoracic echocardiography sequence, each one of the 16 myocardial segments are assigned a score from 1 to 4. The scores for 16 segments are scaled as normokinesia (1 point) or hypokinesia (2 points) or akinesia (3 points) or dyskinesia (4 points). A score of 1.0 is considered normokinetic, and a score of 3.0 correlated as akinetic.	12 months after treatment
Secondary	B-natriuretic peptide level	Laboratory test which is measured in picograms per milliliter (pg/ml).	12 months after treatment
Secondary	6-minute walk test	6-minute walk test is measured in meters.	12 months after treatment
Secondary	All-cause death	Rate of patients with a mortality event due to any cause	12 months after treatment
Secondary	Target lesion Revascularization	Rate of patients who received additional revascularization for the target lesion (the coronary lesion that was treated at the index procedure)	12 months after treatment
Secondary	Readmssion	Rate of patients who were readmitted due to any cause	12 months after treatment
Secondary	Cardiovascular death	Rate of patients with a mortality event due to cardiovascular cause	12 months after treatment
Secondary	non-Target lesion Revascularization	Rate of patients who received additional revascularization for a non-target lesion (the coronary lesion that was NOT treated at the index procedure)	12 months after treatment
