摘要 目的探讨经导管冠状动脉内注射自体骨髓干细胞(bone marrow stem cells,BMSc)对扩张型心肌病(dilated cardiomyopathy,DCM)治疗的有效性及安全性。方法选择2003年12月-2004年11月我科住院扩张型心肌病患者共8例,其中男5例,女3例,年龄47-72岁。冠状动脉造影排除冠心病后,经导管将已提取单个核细胞的自体BMCs悬液30ml分3次,每隔10分钟,经左冠状动脉注入。移植前及移植后1,2,4,8,16个月进行6分钟步行试验、用超声心动图检查:包括左心室收缩期末内径及舒张期末内径:左心室收缩期末容积和舒张期末容积,计算左心室射血分数、室间隔及左室前壁厚度。治疗前后同时常规使用其他治疗扩张型心肌病药物。结果在术中及术后近期,所有患者均无心功能恶化表现及其他不良反应。随访1个月,患者6分钟步行试验达(352±61)m,而术前仅(301±54)m,差异有统计学意义(P<0.05);左心室射血分数从术前(34.6±5.1)%升高到(42.8±4.7)%,差异有统计学意义。左心室收缩期末内径;左心室舒张期末内径、左心室收缩期末容积、舒张期末容积与术前相比无明显变化。随访1~18个月,患者自觉症状较前缓解,无明显并发症发生。结论经导管冠状动脉内注射自体BMCs治疗扩张型心肌病有一定的疗效,能被患者耐受。
