Stem cells transplantation after acute myocardial infarction (AMI) has been claimed to restore cardiac function. However, this therapy is still restricted to experimental studies and clinical trials. Early un-blinded studies suggested a benefit from stem cell therapy following AMI. More recent blinded randomized trials have produced mixed results and, notably, the last largest pan-European clinical trial showed the inconclusive results. Furthermore, mechanisms of potential benefit remain uncertain. This review analytically evaluates 34 blinded and un-blinded clinical trials comprising 3142 patients and is aimed to: (1) identify the pros and cons of stem cell therapy up to a 6-month follow-up after AMI comparing benefit or no effectiveness reported in clinical trials; (2) provide useful information for planning future clinical programs of cardiac stem cell therapy.
急性心肌梗死(AMI)后进行干细胞移植据称可以恢复心脏功能。然而,这种治疗方法仍然局限于实验研究和临床试验。早期非盲研究表明 AMI 后干细胞治疗有益。最近的盲法随机试验得出了混合的结果,值得注意的是,最后一项最大的泛欧临床研究显示出不确定的结果。此外,潜在益处的机制仍不确定。本综述分析评估了 34 项盲法和非盲法临床试验,共纳入 3142 例患者,旨在:(1)在 AMI 后 6 个月的随访中,确定临床试验报告的获益或无效果,从而分析干细胞治疗的优缺点;(2)为规划未来的心脏干细胞治疗临床项目提供有用的信息。
