Treatment for chronic myocardial infarction
A method of treating chronic post-myocardial infarction including helical needle transendocardial delivery of autologous bone marrow (ABM) mononuclear cells around regions of hypo or akinesia in chronic post-myocardial infarction (MI) patients. The treatment is safe and improves ejection fraction (EF).
1. A method of treating chronic myocardial infarction comprising:
identifying a patient with chronic myocardial infarction with areas of chronic myocardial infarct within the patient's myocardium;
harvesting autologous bone marrow cells from the patient;
concentrating cells from the autologous bone marrow to form a therapeutic preparation of mononuclear cells comprising CD-34 positive cells and CD-133 positive cells;
injecting the therapeutic preparation, at a level of 30,000,000 to 264,000,000 of the concentrated mononuclear cells into the myocardium of the patient proximate an area of chronic infarcted tissue resulting from chronic myocardial infarct, where said injecting is accomplished transendocardially.
2. The method of claim 1 further comprising the step of:
concentrating the cells from the autologous bone marrow to form a therapeutic preparation of the cells, said therapeutic preparation comprising at least 40% CD-34 positive cells, CD-90 positive cells, or CD-133 positive cells or a combination thereof.
3. The method of claim 1 further comprising the step of:
isolating the cells from the autologous bone marrow to form a therapeutic preparation of the cells, said therapeutic preparation comprising at least 40% CD-34 positive cells.
4. The method of claim 1 further comprising the step of:
isolating the cells from the autologous bone marrow to form a therapeutic preparation of the cells, said therapeutic preparation comprising at least 40% CD-133 positive cells.
5. A method of treating chronic myocardial infarction comprising:
identifying a patient with chronic myocardial infarction with areas of chronic myocardial infarct within the patient's myocardium;
harvesting autologous bone marrow cells from the patient;
concentrating cells selected from the group comprising CD-34 positive cells and CD-133 positive cells from the autologous bone marrow cells, and suspending said concentrated cells in solution to form a therapeutic preparation;
injecting the therapeutic preparation into the myocardium of the patient proximate areas of chronic myocardial infarct, where said injecting is accomplished transendocardially.
6. The method of claim 5 further comprising the step of:
concentrating the cells from the autologous bone marrow to form a therapeutic preparation of the cells, said therapeutic preparation comprising at least 40% CD-34 positive cells, CD-90 positive cells, or CD-133 positive cells or a combination thereof.
7. The method of claim 5 further comprising the step of:
concentrating the cells from the autologous bone marrow to form a therapeutic preparation of the cells, said therapeutic preparation comprising at least 40% CD-34 positive cells.
8. The method of claim 5 further comprising the step of:
isolating the cells from the autologous bone marrow to form a therapeutic preparation, said therapeutic preparation of the cells comprising at least 40% CD-133 positive cells.
9. The method of claim 5 further comprising the step of:
concentrating the cells to form a therapeutic preparation, said therapeutic preparation with concentration of CD-34 positive cells, CD-133 positive cells or a combination thereof in the range of 10 8 concentrated cells/ml of solution to 1.2×10 8 concentrated cells/ml of solution.
