TITLE:
摘要: 目的:系统评价左卡尼汀治疗心力衰竭的疗效,为临床提供循证参考。方法:计算机检索Cochrane图书馆、PubMed、Medline、中国期刊全文数据库、万方数据库,收集左卡尼汀治疗心力衰竭疗效的随机对照试验(RCT),提取资料并评价质量后,采用Rev Man 5.1统计软件进行Meta分析。结果:共纳入42项RCT,合计3 494例患者。Meta分析结果显示,左卡尼汀可以显著提高有效率[OR=4.07,95%CI(3.16,5.25),P<0.001]、升高左室射血分数(LVEF)[MD=4.49,95%CI(3.49,5.49),P<0.001]、降低脑钠肽(BNP)水平[MD=-130.17,95%CI(-193.81,-66.52),P<0.001]、增加6分钟步行距离[MD=46.12,95%CI(35.72,56.51),P<0.001],差异均有统计学意义。结论:左卡尼汀治疗心力衰竭疗效较好, 可以显著升高患者的LVEF,降低BNP水平,增加6分钟步行距离。
ABSTRACT: OBJECTIVE: To systematically review the efficacy of L-carnitine in the treatment of heart failure, and provide evidence-based reference for clinical treatment. METHODS: Retrieved from Cochrane Library, PubMed, Medline,CJFD and Wanfang Database,  randomized controlled trials (RCT) about the efficacy of L-carnitine in the treatment of heart failure were collected. Meta-analysis was performed by using Rev Man 5.1 software after data extraction and quality evaluation. RESULTS: Totally 42 RCTs were enrolled, involving 3 494 patients. Results of Meta-analysis showed, L-carnitine can significantly improve the effective rate [OR=4.07,95%CI(3.16,5.25),P<0.001], increase left ventricular ejection fraction (LVEF) [MD=4.49,95%CI(3.49,5.49),P<0.001], decrease brain natriuretic peptide (BNP) levels [MD=-130.17,95%CI(-193.81,-66.52),P<0.001] and improve walking distance in 6 minutes [MD=46.12,95%CI(35.72,56.51),P<0.001], the differences were statistically significant. CONCLUSIONS: L-carnitine has good efficacy in the treatment of heart failure, it can significantly improve LVEF, decrease BNP level and increase walking distance in 6 minutes.
