Abstract:
BACKGROUND: Transplantation of the human umbilical cord blood mononuclear cells (HUCBCs) have received increasing attention, as a promising candidate for the cellular transplantation, but the majority of the existing studies are basic research.OBJECTIVE: To report a patient of extensive anterior-wall acute myocardial infarction with cardiogenic shock and severe heart failure, after treatment of HUCBCs transplantation. METHODS: A 73-year-old female patient with cardiogenic shock and severe heart failure after extensive anterior-wall acute myocardial infarction was treated with percutaneous coronary intervention (three scaffolds implantation) and medications, and she still appeared the symptoms of congestive heart failure, such as severe recurrent dyspnea. 2.4 × 108 HUCBCs (50 mL cell suspension) was injected into the infarcted myocardium through the left anterior descending artery by using coronary micro-guide catheter.RESULTS AND CONCLUSION: The patient reported profound clinical benefit including improvement of heart-failure-associated symptoms after the transplantation. Notably the patient did not experience the cell transplant-related side effects during 4 months of follow-up. The ejection fraction increased from 22% before the transplantation to 53% at 21 days after the transplantation. The B-type natriuretic peptide decreased from 1 730 ng/L before the transplantation, 854 ng/L after the transplantation to 264 ng/L at 21 days after the transplantation. The patient did not appear the symptoms of congestive heart failure, including dyspnea, chest distress and hypodynamia, she returned to daily activity at 4 months of follow-ups. Experimental findings indicate that the HUCBCs transplantation is an effective and safe means for patients cardiogenic shock and severe heart failure after acute myocardial infarction.
