文题释义:
心力衰竭:
是指由于心脏的收缩功能和(或)舒张功能发生障碍,不能将静脉回心血量充分排出心脏,导致静脉系统血液淤积,动脉系统血液灌注不足,从而引起心脏循环障碍症候群,此种障碍症候群集中表现为肺淤血、腔静脉淤血。心力衰竭并不是一个独立的疾病,而是心脏疾病发展的终末阶段。缺血性心力衰竭由动脉粥样硬化、灌注量减少或心肌梗死引起,非缺血性心力衰竭由病毒感染、先天性或特发性疾病引起。无论什么原因引起的心力衰竭,充血性心力衰竭是最后的发展阶段,以心肌细胞坏死、炎症反应和瘢痕形成引起心肌收缩力下降为特点。
左心室射血分数:左心室收缩时并不能将左心室的血液全部射入动脉,左心室射血分数即每搏输出量占左心室舒张末期容积量的百分比。正常成人静息状态下,左心室舒张期的容积约为145 mL,博出量为60-80 mL,一般50%以上属于正常范围,人体安静时的射血分数为55%-65%。射血分数与心肌的收缩能力有关,心肌收缩能力越强,则每搏输出量越多,射血分数也越大。正常情况下左室射血分数为≥ 50%,若小于此值即为心功能不全。

 

摘要
背景:
骨髓干细胞(骨髓间充质干细胞、骨髓单个核细胞)已用于缺血性心力衰竭的临床治疗,但其安全性和有效性仍存在争议。
目的:运用Meta分析方法评价骨髓干细胞移植治疗缺血性心力衰竭的安全性和有效性。
方法:系统检索PubMed、Cochrane Library(2016年第10期)、Embase、CNKI、CBM、VIP、万方数据库中相关的临床随机对照试验。提取数据并行方法学质量评价后,运用RevMan5.3软件进行统计分析。  
结果与结论:①纳入8个临床随机对照试验,合计350例缺血性心力衰竭患者,其中干细胞治疗组191例,常规治疗组159例;②Meta分析结果显示:与常规疗法相比,骨髓干细胞移植能增加患者左心室射血分数[MD=4.68,95%CI(1.79,7.56),P < 0.01],但在降低左心室舒张末期容积[MD=-3.86,95%CI(-9.90,2.17),P =0.21]和左心室收缩末期容积[MD=-3.20,95%CI(-9.21,2.80),P =0.30]方面两者差异无显著性意义;③治疗过程中,两者不良事件发生率差异无显著性意义[RR=0.85,95%CI(0.25,2.89),P=0.79];④当前证据显示,骨髓干细胞移植治疗缺血性心力衰竭的安全性良好,并能增加患者左心室射血分数,但不能改善患者左心室重构。基于现有研究的缺陷,该结论仍需开展长期随访的高质量临床随机对照试验予以证实。

Abstract:

BACKGROUND: The bone marrow stem cells (BMSCs) transplantation has been used for the treatment of ischemic heart failure in clinic. But the efficacy and safety of BMSCs transplantation remains controversial.
OBJECTIVE: To systematically assess the efficacy and safety of BMSCs transplantation on ischemic heart failure through a Meta-analysis.
METHODS: PubMed, Cochrane Library (Issue 10, 2016), Embase, CNKI, CBM, VIP, WanFang were search for relevant randomized controlled trials (RCTs). After data extracting and quality assessing, Meta-analysis was performed using RevMan5.3 software.  
RESULTS AND CONCLUSION: A total of 8 RCTs involving 350 patients, 191 in the BMSCs group and 159 in the conventional therapy group, were included. Meta-analysis results showed that: compared with the conventional therapy, BMSCs transplantation could increase the left ventricular ejection fraction [MD=4.68, 95% CI (1.79, 7.56), P < 0.01]. But there was no significant difference in decreasing left ventricular end-diastolic volume [MD=-3.86, 95% CI (-9.90, 2.17), P=0.21] and left ventricular end-systolic volume [MD=-3.20, 95% CI (-9.21, 2.80), P=0.30]. And the incidence of adverse events was not significantly different [RR=0.85, 95% CI (0.25, 2.89), P=0.79] in the course of the treatment. Overall findings indicate that BMSCs transplantation for ischemic heart failure is safe and able to significantly increase patient’s left ventricular ejection fraction. However, BMSCs transplantation by intracoronary injection may have no effect on the left ventricular remodeling in ischemic heart failure patients. Due to the limitations of current studies, high-quality RCTs are needed to further verify our findings.
