背景:射血分数降低的心力衰竭(HFrEF)是全球普遍存在的心血管疾病,对医疗保健和社会构成重大负担。左心室重塑是HFrEF发生和进展的主要病理,导致发病率和死亡率增加。葛根,一种传统的中草药和食物,在中国通常用于治疗HFrEF。越来越多的证据表明,葛根可以有效逆转HFrEF患者的左心室重塑。这项荟萃分析旨在评估葛根对HFrEF患者左心室重塑的影响。
方法:八个电子数据库,包括PubMed,EMBASE,Clinicaltrials.gov,科克伦图书馆,万方,CNKI,CQVIP,从开始到2023年6月,对CBM进行了文献搜索。包括所有使用葛根治疗HFrEF的随机对照试验(RCT)。Cochrane偏差风险工具用于RCT方法学评估,而ReviewManager5.4.1用于分析数据。
结果:确定了19个RCT,共有1,911名患者(男性1,077名,女性834名)。Meta分析表明,葛根与常规药物(CM)联合用药在提高左心室射血分数方面优于单纯CM(LVEF;MD=6.46,95%CI,4.88至8.04,P<0.00001)。左心室舒张末期内径减小(LVEDD;MD=-4.78,95%CI,-6.55至-3.01,P<0.00001),左心室收缩末期直径(LVESD;MD=-3.98,95%CI,-5.98至-1.99,P<0.00001)和N末端脑钠肽前体(NT-proBNP;MD=-126.16,95%CI,-185.30至-67.03,P<0.0001)。此外,联合用药提高临床有效率(RR=3.42,95%CI,2.54~4.59,P<0.00001),6分钟步行试验(6-MWT;MD=65.54,95%CI,41.77~89.31,P<0.00001),中医证候积分疗效(RR=3.03,95%CI,1.57~5.83,P=0.0009)。关于安全,不良事件无差异(RR=0.59,95%CI,0.22~1.54,P=0.28).
结论:在HFrEF患者中使用葛根联合常规药物在改善心功能和逆转左心室重构方面优于单纯常规药物。此外,联合用药没有增加药物不良事件.鉴于某些限制,未来需要更多的审慎和高质量的临床试验来验证结论。
BACKGROUND: Heart failure with reduced ejection fraction (HFrEF) is a prevalent cardiovascular disease globally, posing a significant burden on healthcare and society. Left ventricular remodelling is the primary pathology responsible for HFrEF development and progression, leading to increased morbidity and mortality.
Pueraria, a traditional Chinese herbal medicine and food, is commonly used in China to treat HFrEF. Accumulating evidence suggests that
pueraria can effectively reverse left ventricular remodelling in HFrEF patients. This meta-analysis aims to assess the impact of
pueraria on left ventricular remodelling in HFrEF patients.
METHODS: Eight electronic databases, including PubMed, EMBASE, Clinicaltrials.gov, Cochrane Library, Wanfang, CNKI, CQVIP, and CBM were searched for literature from inception to June 2023. All randomized controlled trials (RCTs) using
pueraria in the treatment of HFrEF were included. The Cochrane Risk of Bias tool was utilized for RCTs\' methodological evaluation, while
Review Manager 5.4.1 was used to analyze the data.
RESULTS: Nineteen RCTs with a total of 1,911 patients (1,077 males and 834 females) were identified. Meta-analysis indicated that combination medication of pueraria and conventional medicine (CM) was superior to the CM alone in raising left ventricular ejection fraction (LVEF; MD = 6.46, 95% CI, 4.88 to 8.04, P < 0.00001), and decreasing left ventricular end-diastolic diameter (LVEDD; MD = -4.78, 95% CI, -6.55 to -3.01, P < 0.00001), left ventricular end-Systolic diameter (LVESD; MD = -3.98, 95% CI, -5.98 to -1.99, P < 0.00001) and N-terminal pro-brain natriuretic peptide (NT-proBNP; MD = -126.16, 95% CI, -185.30 to -67.03, P < 0.0001). Besides, combination medication improved clinical efficacy rate (RR = 3.42, 95% CI, 2.54 to 4.59, P < 0.00001), 6-min walk test (6-MWT; MD = 65.54, 95% CI, 41.77 to 89.31, P < 0.00001), and TCM syndrome score efficacy (RR = 3.03, 95% CI, 1.57 to 5.83, P = 0.0009). Regarding safety, no difference was observed for adverse events (RR = 0.59, 95% CI, 0.22 to 1.54, P = 0.28).
CONCLUSIONS: The use of pueraria combined with conventional medicine in HFrEF patients has superiority over conventional medicine alone in ameliorating cardiac function and reversing left ventricular remodeling. Moreover, combination medication has no increase in adverse drug events. Given some limitations, more prudence and high-quality clinical trials are needed in the future to verify the conclusions.
