概括
在血液透析 (HD) 期间,末期病 (ESKD) 患者的心率变化 (HRV) 的增加与和控制不佳有关. 这表明电解质失衡可能导致心脏自主功能障碍.
科学领域:
- 腎臟病學 (nephrology) 是一種醫學.
- 心脏病学 心脏病学
- 生物医学工程 生物医学工程
背景情况:
- 自主功能障碍是末期病 (ESKD) 患者已知的并发症.
- 从心电图 (ECG) 记录中分析心率变化 (HRV),有助于诊断自主功能障碍.
- 关于使用实时ECG和HRV来预测ESKD患者血液透析 (HD) 效率的数据有限.
研究的目的:
- 研究ESKD患者在HD期间HRV和电解质水平之间的关联.
- 在现实环境中探索HRV对高清效率的预测价值.
主要方法:
- 持续的实时心电图监测在50名ESKD患者身上进行,这些患者在HD治疗期间进行了持续的心电图监测.
- 从心电图记录分析HRV,测量HD前后的电解质水平 (K+,P+).
- 基于HD前后的电解质水平进行了HRV的比较.
主要成果:
- 在低 (K+) 水平 (<0.5 mEq/L) 和较小的酸盐 (P+) 水平变化 (<2 mEq/L) 的患者中观察到更高的时间和频率域HRV.
- 相反,较高的K+水平 (≥0.5mEq/L) 和较大的P+水平变化 (≥2mEq/L) 与较低的HRV相关.
- 电解质变化较低的患者表现出较高的节律失常事件发生率,尽管平均心率没有显著差异.
结论:
- 在ESKD患者的HD期间HRV升高与控制不良的和酸盐水平独立相关.
- 实时监测始终显示出这种关联,表明在HD期间电解质变化不足可能导致心脏自主功能障碍.

Renal failure occurs when the kidneys lose their ability to filter waste products from the blood effectively. It can be classified into two types: acute renal failure (ARF) and chronic renal failure (CRF).
Acute kidney injury develops suddenly and can be caused by pre-renal causes (e.g., hypovolemia, shock), intrinsic renal causes (e.g., acute tubular necrosis), or post-renal causes (e.g., urinary obstruction). In contrast, chronic renal failure progresses gradually over time and is often...

Heart Failure Drugs: Diuretics
370
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...

Factors Affecting Renal Clearance: Renal Impairment
91
Renal dysfunction significantly impairs the renal clearance of drugs, leading to potential complications in drug therapy. Renal failure, which can be caused by various factors, poses a significant challenge in the elimination of drugs from the body.
One condition associated with renal failure is uremia. Uremia is characterized by impaired glomerular filtration and fluid accumulation in the body. This condition hinders the renal clearance of drugs, resulting in drug accumulation and potential...

Pathophysiology of Heart Failure
1.6K
Heart failure (HF) is a progressive syndrome involving ventricles that leads to inadequate cardiac output. It can be classified based on location and output or ejection fraction. Ejection fraction (EF) is an essential measurement in the diagnosis and surveillance of HF. Reduced EF corresponds to systolic heart failure (HFrEF). However, HF with preserved ejection fraction (HFpEF) is becoming increasingly prevalent. Also known as diastolic HF, this form of HF is related to aging. The...
