摘　　要：目的观察经冠状动脉自体骨髓单个核细胞(mononuclearbonemarrowcell,MBMC)移植治疗缺血性心力衰竭(IHF)的可行性、效果、安全性及不良反应。方法2002年12月至2004年3月,41例缺血性心力衰竭患者入选此前瞻性研究,分为两组。(1)细胞移植组:14例经梗死相关冠状动脉超选择性移植,于气囊充盈下高压注入2mLMBMC(2×106/mL),重复注入6～8次,平均共计(3.28±0.44)×107MBMC;13例经冠状动脉选择性移植,气囊未充盈下高压注入移植细胞,细胞数与上相同。(2)对照常规治疗组:共14例,除细胞移植外其他治疗均相同。结果27例细胞移植患者手术均安全,2例于细胞注入后15～30min感发冷,30min后好转;2例细胞注入时出现短暂自限性室性早搏,术后48h持续心电监测未出现新的心律失常;随访3个月时,细胞移植组心力衰竭症状明显好转,射血分数(EF)和心搏量(SV)增加,左心室收缩末期容积(LVESV)减少,正电子发射体层摄影(PET)心肌代谢显像示代谢活力心肌增加(23.94±7.28)%(P=0.015);术后第3天、第7天脑钠素(BNP)水平较术前明显下降,心钠素(ANP)水平在术后第7天明显上升;随访6个月1例心力衰竭加重再度住院,无一例死亡。对照组心功能恶化,再入院率71.4%,2例死亡。结论自体骨髓单个核细胞经冠状动脉移植修复心肌对改善心功能是安全有效的。Objective To investigate the possibility, effect and safety of intracoronary autnlngous moronuclear bone marrow cell （MBMC） transplantation in patients with ischemia heart failure （IHF）. Methods 41 patients with H-IF were enrolled in this prospective nonrandomized study. 14 patients were transplanted with autologous MBMC via a balloon catheter placed into the infarct-related artery during balloon dilatation by highpressure infusion, which was performed 6-8 times for 2 minutes each. 13 patients were transplanted via selective the infarct-related arteries by highpressure infusion. Results There were no major periproedural complications. Two patients had limited premature ventricular contractions during cell infusion forseveral seconds. Two patients felt cold after 15-30 minutes infusing cell and got better several minutes later. There were no new onset of arrhythmias found on 48 h ECG monitoring. After 3 months of follow up, the symptoms and cardiac function were significantly improved in the transplantation group. FDG-PET analysis revealed a significant increase in myocardial metabolism （23.94 ± 7.28 ）% （ P = 0.015 ）. Plasma BNP lever decreased signiilcatly at 3 days and 7 days after transplantation than before transplantation （ P 〈 0.05 ） . However, ANP increased after cell transplantation （ P 〈0.05）. In the control group, cardiac function became worse and the rehospitalization rate was 71.4%. Two patients died of pump failure at 6-month follow up. No patient died and only one patient was readmitted for lower extremities edema in the transplantation group. Conclusion Intracoronary transplantation of autologus MBMC is safe and effective.
