Bone marrow stem cell transplantation for improving heart function of patients with acute myocardial infarction:a systematic review / 中国组织工程研究

ABSTRACT

BACKGROUND:Although increasing studies have shown that autologous bone marrow stem celltransplantation can treat myocardial infarction, but there is a lack of large-scale multi-center randomized control ed trials to il ustrate the therapeutic effectiveness of autologous bone marrow stem celltreatment for myocardial infarction. OBJECTIVE:To systematical y evaluate the improvement of heart function in patients with myocardial infarction undergoing autologous bone marrow stem celltransplantation. METHODS:Cochrane Central Register of Control ed Trials (Central), MEDLINE, EMbase, PEDro (www.pedro.org.au), OpenSIGLE, National Technical Information Service (NTIS), CNKI, VIP database (VlP), Wanfang Data and Chinese biomedical literature database (CBM) were searched for the randomized control ed trials addressing bone marrow stem celltransplantation for heart function in patients with myocardial infarction. The bibliographies of the included studies were also searched. The time span was from database establishment to November 2012. The extracted data were analyzed by RevMan5.1. RESULTS AND CONCLUSION:A total of 14 randomized control ed trials were included. Results from the meta-analysis showed that the ejection fraction and cardiac output of patients undergoing bone marrow stem celltransplantation was significantly different from those of patients without celltransplantation (WMD=5.23, 95%CI (0.73, 9.72), P<0.01;WMD=1.69, 95%CI (1.23, 2.16), P<0.000 01). Current evidence has demonstrated that bone marrow stem celltransplantation can remarkably improve the ejection fraction and cardiac output of myocardial infarction patients, which can be clinical y recommended for improvement of heart function. Due to the limitations of the included studies, more large-sample, multi-center high-quality randomized control ed trials are required to further verify the therapeutic methods and effectiveness.
