Moreover, it is an important modifiable risk factor for progression to ESRD and its overall cardiovascular morbidity and mortality. Objective: to evaluate, prospectively, the role of Renin-Angiotensin-Aldosterone System blockade (RAAS) in HTN, resistant to 3 conventional antihypertensives, in patients on maintenance hemodialysis (MHD). Patients and methods: A total of 52 such patients were treated with Ramipril and 5 with Losartan after intolerable cough/shortness of breath following Ramipril-use. None of the patients had fluid depletion, renal artery stenosis and primary endocrinopathy. The study group was compared to a matched control group of MHD patients with normal blood pressure following 3 drugs-combination therapies. Results: All patients, with resistant HTN, had significant activation of RAAS system prior to treatment compared to inactive one in the control group. In those with resistant HTN, control of HTN, was established within 2 weeks of therapy and was associated with suppression of the RAAS. Such therapy was associated with minor side effects. Conclusion: Our study has shown that RAAS blockade is safe and effective in controlling such resistant HTN in MHD patients.展开更多
目的系统评价沙库巴曲缬沙坦(ARNI)对比肾素-血管紧张素-醛固酮系统(RAAS)抑制剂(ACEI/ARB)在治疗老年顽固性心力衰竭(RHF)患者的疗效和安全性。方法检索英文数据库(PubMed、Embase、Web of science、Conchrane Library)及中文数据库(...目的系统评价沙库巴曲缬沙坦(ARNI)对比肾素-血管紧张素-醛固酮系统(RAAS)抑制剂(ACEI/ARB)在治疗老年顽固性心力衰竭(RHF)患者的疗效和安全性。方法检索英文数据库(PubMed、Embase、Web of science、Conchrane Library)及中文数据库(知网、万方、维普、CBM)中已发表的随机对照试验(RCTs),采用Cochrane风险评估工具对文献质量进行评价,采用RevMan及Stata软件进行Meta分析。结果纳入10篇文献共1118例老年RHF患者。结果显示,应用ARNI组(研究组)氨基末端脑钠尿肽前体(NT-proBNP)(MD=-282.61,95%CI-344.56~-220.66,P<0.05)、左心室舒张末期内径(LVEDD)(MD=-3.48,95%CI-4.58~-2.39,P<0.05)低于应用ACEI/ARB组(对照组);左心室射血分数(LVEF)(MD=6.35,95%CI 4.65~8.06,P<0.05)、有效率(OR=2.449,95%CI 1.851~3.241,P<0.05)明显高于对照组。两组肾功能损害、头晕、高血钾比较无差异,低血压发生率低于对照组。结论与ACEI/ARB相比,ARNI可显著改善心室重构,进一步改善老年RHF患者心功能,并且安全性良好。展开更多
