目前，患者心脏病发作（为心脏供血的动脉阻塞）后的标准疗法是利用一个小球囊直接扩张冠状动脉，即初始血管成形术，然后使用支架再通被阻塞的血管；这两种方法的结合可以使相关死亡率下降33%。最近，已有研究测试了作为血管成形术辅助疗法的骨髓干细胞/祖细胞，在预防心脏病导致的心肌受损方面的效果。分析2007年的首个随机对照试验发现，通过对心脏功能替代指标进行测量，这种新疗法比常规疗法可能有所改进。然而，我们仍需要进一步的试验来证实，当这种新疗法在大规模应用于人群时，患者心脏功能的短期改变能否转变为长期改善，以及此疗法会不会产生不良反应。到目前为止，本系统评价纳入了13个临床试验，研究对象不到1000名患者。
