概括
末期病 (ESKD) 患者的动脉静脉 (AVF) 导致心脏重塑,特别是在右心室. 流体过载和高的左心室填充压力与这种重塑有关,而不是AVF流本身.
科学领域:
- 心脏病学 心脏病学
- 腎臟病學 (nephrology) 是一種醫學.
- 血管外科 血管外科
背景情况:
- 动脉静脉 (AVF) 在末期病 (ESKD) 患者的血液透析中至关重要.
- AVF可以导致心脏重塑,增加心力衰竭和心血管死亡的风险.
- 了解AVF创建后的心脏变化对于患者管理至关重要.
研究的目的:
- 评估ESKD患者在AVF形成后的心脏重塑.
- 为了确定与心脏重塑相关的参数.
- 评估AVF流对心脏结构和功能的影响.
主要方法:
- 这是一项前性,单中心研究,涉及20名ESKD患者.
- 在AVF创建之前和之后进行的2D和3D回声心电图.
- 测量AVF流量,评估心室体积 (LVEDVi,RVEDVi) 和静脉功能 (纵向应变,3D喷射分数).
主要成果:
- 在AVF创建后观察到显著的双心膜扩张 (p < 0.05).
- 右心室显示出最明显的重塑.
- 右心室重塑独立地与体积过载和左心室填充压力升高有关 (p = 0.003,p = 0.030).
结论:

01:25Hemodialysis I: Introduction
290
Hemodialysis (HD) is a medical treatment that artificially removes waste products, excess fluids, and toxins from the blood when the kidneys are no longer able to perform these functions effectively. In this process, blood is filtered through a semipermeable membrane, allowing for the selective removal of waste while preserving necessary components like blood cells and proteins. Hemodialysis is typically performed in patients with end-stage renal disease (ESRD) or severe kidney...

Right Heart Catheterization: An OverviewRight heart catheterization is an invasive diagnostic procedure that measures right-sided cardiac and pulmonary artery pressures, calculates cardiac output, and identifies intracardiac shunts. It provides detailed hemodynamic data essential for diagnosing and managing various cardiovascular conditions, such as pulmonary hypertension.Access SitesCommon access sites for right heart catheterization include the internal jugular vein in the neck region, the...
