概括
在接受TAVR的严重大动脉狭窄患者中,流体过载显著增加了风险. 与单独的临床判断相比,生物阻抗光谱导向解压改善了结果和生活质量.
科学领域:
- 心脏病学 心脏病学
- 医疗器械 医疗器械
- 临床试验 临床试验
背景情况:
- 流体过载 (FO) 对严重大动脉狭窄症 (AS) 患者构成重大风险,增加了心力衰竭和门更换后死亡的可能性.
- 生物阻抗光谱 (BIS) 为量化流体过载提供了一个客观的方法.
研究的目的:
- 调查BIS指导的脱血是否能改善AS患者的预后和生活质量,FO患者接受过导管大动脉置换 (TAVR).
主要方法:
- 一项随机对照试验,涉及232名重症AS患者,计划接受TAVR.
- 患有FO的患者 (n=111) 被随机分配到BIS引导的脱血或TAVR后单独进行临床判断.
- 还包括了121名没有FO的患者的对照组. 主要终点:心力衰竭住院和/或12个月内全因死亡的复合结果.
主要成果:
- 与非BIS指导的组相比,BIS指导的脱塞组显示主要终点的发生率明显较低 (12.7%vs32.1%).
- 在BIS指导组的结果与euvolemic对照组相似.
- 由BIS指导的减压导致生活质量得到了更大的改善,这是堪萨斯城心肌病问卷测量的结果.
结论:
- 定量BIS导向的脱塞和强化TAVR后管理改善了FO重症AS患者的治疗结果和生活质量.
- 这种方法优于仅以临床判断为指导的解堵.

350
Heart failure and kidney perfusion are interconnected in a complex way. Reduced renal perfusion and venous congestion are two significant factors that contribute to renal dysfunction in heart failure. The kidneys, primarily responsible for fluid balance in the body, are adversely affected due to compromised cardiac output and increased venous pressure. In response to reduced renal perfusion, the kidneys activate neurohumoral mechanisms to restore balance. However, these mechanisms can be...

01:26Heart Failure Drugs: Inhibitors of Renin-Angiotensin System

The activation of the sympathetic nervous system and the renin-angiotensin-aldosterone system (RAAS) contributes to cardiac remodeling, and inhibiting the RAAS is a pharmacological target in heart failure management. As a result, neurohumoral modulation is a crucial treatment principle for managing heart failure. This approach involves using medications like ACE inhibitors (ACEIs), angiotensin receptor blockers (ARBs), β-blockers, mineralocorticoid receptor antagonists (MRAs), and neutral...
