Stem cell therapy for cardiovascular disorders - our clinical experience

Area of Science:

• Cardiology
• Regenerative Medicine
• Stem Cell Therapy

Background:

• Limited treatment options exist for end-stage heart failure due to cardiomyopathy.
• Autologous bone marrow stem cells offer a potential therapeutic approach.
• Stem cells may replace damaged cells, stimulate local growth via paracrine effects, and recruit other stem cells.

Purpose of the Study:

• To evaluate the efficacy of autologous bone marrow-derived stem cells in patients with end-stage heart failure.
• To assess functional improvement and quality of life following stem cell transplantation.

Main Methods:

• A study involving 13 patients with cardiomyopathy (ischemic dysfunction, dilated cardiomyopathy, pulmonary hypertension).
• Patients received isolated and expanded CD34+ cells from bone marrow.
• Stem cells were administered via intracoronary injection, direct myocardial injection, or intrapulmonary delivery.

Main Results:

• All patients demonstrated functional improvement in myocardial function.
• Non-invasive investigations confirmed enhanced cardiac function.
• Patients reported an improved quality of life.
• Follow-up ranged from 6 months to 2 years.

Conclusions:

• Bone marrow-derived stem cells show encouraging results in treating cardiomyopathy.
• Further studies are warranted to confirm these findings and explore long-term outcomes.
