丹红注射液对急性心肌梗死PCI围手术期心功能和TIMI血流影响的Meta分析

目的:系统评价丹红注射液对急性心肌梗死(AMI)经皮冠状动脉介入治疗(PCI)围手术期心功能和心肌梗塞溶栓治疗(TIMI)血流分级的影响。方法:计算机检索CNKI,万方数据库,维普数据库,Pub Med,CBM,Web of Science,The Cochrane Library共7个数据库,全面采集在PCI围手术期应用丹红注射液治疗急性心梗的临床试验,采用Cochrane风险评价表进行文献质量评价,运用Revman 5.3软件进行Meta分析。结果:共纳入12个临床试验,包含1131例患者,其中丹红治疗组569例,对照组562例,结果显示在常规治疗的基础上加入丹红注射液治疗,患者的左室射血分数明显增高[均数差(MD)=6.62,95%可信区间(CI)(4.91,8.34),P<0.00001],TIMI分级3级患者明显增多[相对危险度(RR)=0.22,95%CI(0.12,0.41),P<0.00001],脑利钠肽水平明显降低[MD=-151.86,95%CI(-247.00,-56.72),P=0.002]。结论:丹红注射液可以提高急性心梗PCI围手术期心功能和增加TIMI血流的分级。

Outcomes of coronary artery bypass grafting in patients with heart failure with a midrange ejection fraction

BackgroundCoronary artery bypass grafting (CABG) improves survival in patients with heart failure and severely reduced left ventricular systolic function (LVEF). Limited data exist regarding adverse cardiovascular event rates after CABG in patients with heart failure with midrange ejection fraction (HFmrEF; LVEF > 40% and < 55%).MethodsWe analyzed data on isolated CABG patients from the Veterans Affairs national database (2010-2019). We stratified patients into control (normal LVEF and no heart failure), HFmrEF, and heart failure with reduced LVEF (HFrEF) groups. We compared all-cause mortality and heart failure hospitalization rates between groups with a Cox model and recurrent events analysis, respectively.ResultsIn 6533 veterans, HFmrEF and HFrEF was present in 1715 (26.3%) and 566 (8.6%) respectively; the control group had 4252 (65.1%) patients. HFrEF patients were more likely to have diabetes mellitus (59%), insulin therapy (36%), and previous myocardial infarction (31%). Anemia was more prevalent in patients with HFrEF (49%) as was a lower serum albumin (mean, 3.6 mg/dL). Compared with the control group, a higher risk of death was observed in the HFmrEF (hazard ratio [HR], 1.3 [1.2-1.5)] and HFrEF (HR, 1.5 [1.2-1.7]) groups. HFmrEF patients had the higher risk of myocardial infarction (subdistribution HR, 1.2 [1-1.6]; P = .04). Risk of heart failure hospitalization was higher in patients with HFmrEF (HR, 4.1 [3.5-4.7]) and patients with HFrEF (HR, 7.2 [6.2-8.5]).ConclusionsHeart failure with midrange ejection fraction negatively affects survival after CABG. These patients also experience higher rates myocardial infarction and heart failure hospitalization.     

八段锦干预心力衰竭患者疗效的Meta分析

目的:评估八段锦干预心力衰竭的疗效及安全性。方法:搜索中国知网数据库、中国生物医学文献数据库、万方数据库以及维普中文全文数据库；PubMed、Cochrane Library、web of science、EMBASE。检索时间为建库至2019年2月28日。对纳入的随机对照试验（RCT)用Cochrane手册进行偏倚风险评估，用Rev Man 5.3软件进行Meta分析。结果:纳入6篇文献，7个随机对照研究，共计543例心力衰竭患者。与对照组比较，观察组MLHFQ减少[MD=10.88,95%CI=（8.22，13.54）]，6分钟步行试验(6MWT)提高[MD=107.81,95%CI=（75.83，139.78）]，左心室射血分数(LVEF)提高[MD=3.62,95%CI=（2.04，5.19）]，B型利钠肽(BNP)降低[MD=73.32,95%CI=（45.12，101.53）]，临床疗效[OR=4.00,95%CI=（1.35，11.83）]，中医证候评分[OR=4.57,95%CI=（2.03，10.31）]。结论:八段锦可改善心力衰竭患者的心功能，用于稳定期的康复治疗。
