摘要
目的系统评价适应性支持通气(ASV)对慢性心力衰竭(CHF)合并睡眠呼吸障碍疾病(SDB)患者心功能的长期疗效。方法检索1970年1月-2015年12月在PubMed、Cochrane、EMBASE和中国生物医学文献数据库、中文期刊文献数据库、万方数据库公开发表的临床对照研究。纳入标准为左心室射血分数≤55%、呼吸暂停低通气指数≥1s次/h、随访周期超过4周。经两名作者独立交叉进行数据提取,以改良Jadad量表进行质量评估,应用RevMan5.3软件进行Meta分析。结果纳入13项研究,共计503例,442例完成4周治疗,其中233例使用ASV治疗,216例为对照(其中7例为交叉对照)。与对照组比较,ASV治疗后,左心室射血分数明显增加[加权均数差(WMD)=3.72,95%CI:1.80—5.64,P〈0.011,呼吸暂停低通气指数明显降低(WMD=-18.63,95%CI:-26.19--11.08,P〈0.01),6分钟步行距离明显增加(WMD=28.72,95%CI:2.26-55.18,P=0.03),血浆N端脑钠肽前体降低(WMD=-744.03,95%CI:-1262.45--225.62,P〈0.05)。结论4N以上ASV可以改善慢性心力衰竭合并SDB患者的左心室射血分数、增加6分钟步行距离,降低呼吸暂停低通气指数,降低血浆N段脑钠肽前体水平。
Objective To evaluate the long-tern effect of adaptive servo ventilation (ASV) on patients with chronic heart failure (CHF) and sleep-disordered breathing (SDB). Methods The controlled clinical articles were searched included in PubMed, Cochrane, EMBASE and CBM, CJFD, WangFang Database from Jan. 1970 to Dec. 2015. Included standard: left ventricular ejection fraction (LVEF) 455%, apnea hypopnea index (AHI) ≥ 15/h, follow up period over 4 weeks. After quality assessment (modified Jadad score) and data extraction by two independent reviewers, mete analysis was performed with RevMan 5.3 software. Results Thirteen studies were recruited including 442 cases being followed over 4 weeks [ASV group 233 cases and control group 216 cases (corssover design 7)]. Compared to control group, LVEF increased [weighted mean difference (WMD)=3.72, 95%CI: 1.80- 5.64, P〈0.01] and AHI decreased significantly (WMD=-18.63, 95%CI: -26.19--11.08), the distance walked in 6 minutes increased (WMD=28.72, 95%CI: 2.26-55.18, P=0.03) and plasma N terminal brain natriuretic peptide precursor (NT-pro BNP) decreased significantly (WMD=-744.03, 95%CI: -1262.45--225.62, P〈0.05) in ASV group. Conclusion Over 4 weeks ASV may improve LVEF and AHI, increase 6-min walking distance and decrease NT-pro BNP in patients with CHF and SDB.
