摘要

摘要: 目的:了解重组人脑利钠肽(rhBNP)对急性心肌梗死(AMI)后急性失代偿性心力衰竭(HF)患者循环内分泌激素及左室功能的影响,并评判其临床疗效和安全性。方法:AMI并发急性失代偿性HF患者58例,随机分为rhBNP组26例和硝酸异山梨酯组32例,在标准抗缺血、抗HF治疗的基础上,持续静脉应用rhBNP或硝酸异山梨酯48h,分别于治疗前和治疗后6h、24h及72h,检测血浆肾素活性(PRA)、血管紧张素Ⅱ(AngⅡ)和醛固酮(ALD)浓度;治疗前及治疗后72h测定血BNP、超声心动图测定左室舒张末期内径(LVDd)及左室射血分数(LVEF);同时比较30d内主要不良心脏事件(MACE)的发生情况。结果:与硝酸异山梨酯组比较,rhBNP组血浆PRA、AngⅡ、ALD治疗6h后即降低(均P<0.05),72h时仍保持较低水平(均P<0.01);治疗后72hBNP下降(P<0.01),LVDd及LVEF明显改善(P<0.05,P<0.01),30dMACE事件发生率rhBNP组显著低于硝酸异山梨酯组(P<0.05)。结论:rhBNP对AMI伴HF患者的血浆肾素、AngⅡ和ALD水平有快速而持续的抑制作用,可以显著改善左室功能,同时降低30d内MACE事件发生率。

Abstract: Objective:To investigate the clinical efficacy of recombinant human brain natriuretic peptide(rhBNP) on endocrine hormone and left ventricular function of acute decompensated heart failure(ADHF) patients resulted from acute myocardial infarcfion(AMI). Method:Fifty-eight patients with AMI-ADHF were randomly divided into rhBNP group(n=26) and isosorbide mononitrate group(n=32).They were all received standard anti-ischemic and anti-heart failure treatment.We detected plasma renin activity(PRA),angiotensin Ⅱ(Ang Ⅱ) and aldosterone(ALD) concentration before treatment and after 6,24 and 72 hours.Blood BNP,left ventricular end-diastolic diameter(LVDd) and left ventricular ejection fraction(LVEF) were determined before treatment and after 72 hours.All patients were followed up for l month to record the main adverse cardiac event(MACE). Result:Compared with isosorbide mononitrate group,plasma PRA,AngⅡ,ALD were significantly decreased at 6 h(P<0.05),and still remained the lower level at 72 h.Blood BNP was decreased(P<0.05),LVDd and LVEF were improved significantly(P<0.05,P<0.01) at 72 h.MACE were lower in rhBNP group within 30 days than those of isosorbide mononitrate group(P<0.05). Conclusion:In patients with AMI-ADHF,rhBNP can inhibit plasma renin,AngⅡ and ALD,significantly improve left ventricular function and reduce the rate of the MACE within 30 days.
