摘要:

背景:干细胞移植到受损的心脏组织,可以大量分化为心肌细胞,这项研究为缺血性心脏病治疗带来新的希望。
目的:探讨干细胞移植治疗缺血性心脏病的可行性与安全性。
方法:分析干细胞移植治疗缺血性心脏病安全性和可行性的多种试验方法。REPAIR-AMI试验是一项分析急性心肌梗死后即刻冠脉内移植骨髓祖细胞治疗效果的随机双盲、安慰剂对照的多中心研究;MAGIC Cell-3-DES试验是评价粒细胞集落刺激因子动员的干细胞疗法的安全性和冠脉内注射动员的外周血干细胞对急性心肌梗死和陈旧性心肌梗死的效果;BOOST试验是心肌梗死后经冠脉移植自体骨髓细胞的随机对照研究。PROTECT-CAD试验是一项随机、对照的直接将干细胞注入心肌治疗慢性缺血性心肌病的临床试验。
结果与结论:干细胞移植可以改善左心室的收缩功能和舒张功能以及冠脉血流储备,相关研究也得到验证。对于干细胞移植治疗缺血性心脏病,可以增加左室射血分数,临床事件较少,在药物洗脱支架治疗的基础上,干细胞治疗并不增加再狭窄风险。干细胞移植治疗缺血性心脏病安全可行,未来还需要进行大样本、长时间的大规模多中心的随机对照研究,来进一步评价其疗效和风险。

Abstract:

BACKGROUND: The stem cells transplanted into the damaged heart tissues can differentiate into cardiomyocytes, which bring new hope for the research of ischemic heart disease.
OBJECTIVE: To explore the feasibility and safety of stem cell transplantation for the treatment of ischemic heart disease.
METHODS: Various experimental methods to the feasibility and safety of stem cell transplantation for the treatment of ischemic heart disease were analyzed. REPAIR-AMI experiment was a randomized and double-blind and placebo-controlled multi-center study that used to analyze the therapeutic effect of intracoronary transplantation of bone marrow progenitor cells immediately after acute myocardial infarction. MAGIC Cell-3-DES experiment was used to evaluate the safety of granulocyte colony-stimulating factor mobilized stem cell therapy and the effect of intracoronary injection of mobilized peripheral blood stem cells on the treatment of acute myocardial infarction and old myocardial infarction. BOOST experiment was the randomized controlled study on autologous bone marrow cell transplantation through coronary vein after myocardial infarction. PROTECT-CAD experiment was the randomized controlled clinical trial about the direct injection of stem cells into the myocardial for the treatment of ischemic heart disease.
RESUTLS AND CONCLUSION: Stem cell transplantation may improve the left ventricular systolic function and left ventricular diastolic function as well as the coronary flow reserve, and the related studies have been confirmed. Stem cell transplantation for the treatment of ischemic heart disease can increase the left ventricular jection fraction. As the less clinical accident, stem cell therapy cannot increase the risk of restenosis based on the treatment of drug-eluting stents. It is safe and feasible of stem cell transplantation for the treatment of ischemic heart disease. Large sample, long scale and multi-center randomized controlled studies are needed to further evaluate the effect and risk of stem cell transplantation.
