概括
在急性不补偿性心力衰竭 (ADHF) 中,体积过载与功能下降和透析风险增加有关. 然而,在随访期间,波动的体积过载与功能变化无关.
科学领域:
- 心脏病学 心脏病学
- 腎臟病學 (nephrology) 是一種醫學專業.
- 临界护理医学 临界护理医学
背景情况:
- 据估计的球过率 (eGFR) 显示,功能下降是急性不补偿性心力衰竭 (ADHF) 中不良结果的显著预测因素.
- 之前关于体积过载作为ADHF患者EGFR下降的危险因素的研究已经产生了不一致的结果.
研究的目的:
- 研究通过中央静脉压 (CVP) 和肺毛细血管压 (PCWP) 评估的体积过载与ADHF成年患者的功能之间的关联.
- 确定体积过载是否预测了基线eGFR,医院eGFR斜率,以及需要透析.
主要方法:
- 在2015年至2021年期间,对753名成人患者进行了回顾性观察性研究,这些患者患有ADHF,需要右心导管治疗.
- 统计模型,包括限制立方线,线性混合模型和Cox比例危险回归,用于分析CVP,PCWP和脏结果 (eGFR,透析启动) 之间的关系.
- 进行了敏感性分析,将死亡视为启动透析的竞争风险.
主要成果:
- 较高的CVP和PCWP显着与较低的基线eGFR和住院期间eGFR的更急剧下降有关.
- 增加的CVP和PCWP与需要透析的风险增加有关,平均随访时间为33个月 (CVP的调整HR为1.49;PCWP为1.30).
- CVP和PCWP的变化与eGFR或透析风险的同时变化无关.
结论:
- 在ADHF患者中,体积过载明显与基线功能受损,eGFR下降加速,以及启动透析的可能性更高有关.
- 在随访期间,体积过载波动的程度并不能预测EGFR或透析风险的后续变化.

01:22Heart Failure Drugs: Diuretics
505
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...

Medical Management of Acute Decompensated Heart Failure (ADHF)The primary goals of therapy for patients hospitalized with acute decompensated heart failure (ADHF) include:Relieving symptomsOptimizing volume statusSupporting oxygenation and ventilationMaintaining cardiac output (CO) and end-organ perfusionIdentifying and addressing the cause of ADHFPreventing complicationsProviding patient education on factors precipitating HF exacerbationPlanning for dischargeOngoing monitoring and assessment...

59
Systolic Heart Failure and Compensatory MechanismsSystolic heart failure (also termed HFrEF, Heart Failure with Reduced Ejection Fraction) is the most prevalent type of heart filure. It results in a decreased volume of blood being pumped from the ventricle. The aortic arch and carotid sinuses have baroreceptors that detect reduced blood pressure, triggering the sympathetic nervous system (SNS) to release epinephrine and norepinephrine. Initially, this response aims to boost heart rate and...

Acute Kidney Injury (AKI) requires a collaborative healthcare approach to restore renal function and prevent complications. Essential management strategies involve monitoring fluid and electrolyte balance, adjusting medications, initiating dialysis when necessary, and providing nutritional support.Fluid and Electrolyte ManagementFluid Monitoring: Regularly monitoring body weight, central venous pressure, and urine output helps detect fluid imbalances early. Patient intake and output are...

Additional therapies for treating patients with heart failure (HF) may include procedural interventions, supplemental oxygen, the management of sleep disorders, and nutritional therapy.Procedural InterventionsImplantable Cardioverter-Defibrillator: For patients at risk of life-threatening arrhythmias due to severe left ventricular dysfunction, an Implantable Cardioverter-Defibrillator (ICD) can detect and terminate these arrhythmias, preventing sudden cardiac death and improving survival rates.

Nursing management is essential for preventing complications, maintaining stability, and improving patients' quality of life in chronic kidney disease (CKD). By using a structured approach, nurses help slow CKD progression and support effective patient care.1. Comprehensive patient assessmentEffective management begins with nurses reviewing the patient’s medical history, and identifying key risk factors like diabetes, hypertension, and nephrotoxic drug use. Nurses assess signs of...
