Clinical research for treatment of angina with autologous bone marrow mononuclear cell transplantation

Abstract

Objective To evaluate the safety and efficacy of transplantation of autologous bone marrow mononuclear cell (BMMNC) for angina.Methods Fifteen patients who had suffered from unstable angina were selected to receive intraeoronary transplantation immediately following percutaneous coronary intervention (PCI) with BMMNC (BMMNC group).Sixteen patients who had suffered from unstable angina only received treatment of regular medicine and PCI (non-BMMNC group).Two-D echocardiography,singlephoton emission computed tomography (SPECT) imaging and Holter monitoring electrocardiogram were checked up before and 6 months after the procedure.The complications of myocardial infarction,arrhythmia etc,efficacy for angina were evaluated during the procedure and 3,6 months after the procedure.Results The intracoronary injection of BMMNC did not result in myocardial infarction and arrhythmia during the transplantation.Efficacy parameters including nitroglycerine usage per week,exercise time 3 months after the procedure showed that BMMNC group were better than non-BMMNC group (P <0.05).Efficacy parameters including angina frequency per week,nitroglycerine usage per week,exercise time,and Canadian Cardiovascular Society class 6 months after the procedure showed that BMMNC group were better than nonBMMNC group[(12.6 ± 9.3) times/week vs.(18.0 ± 16.3) times/week,(-4.1 ± 14.7) mg/week vs.(4.8 ± 37.9)mg/week,(2.5±1.3)min vs.(2.0 ± 2.1) min, (-1.4 ± 1.0) grades vs.(-0.8 ± 1.7) grades](P＜0.05).Conclusion Intracoronary transplantation of autologous BMMNC is safe and efficient for angina.
