背景情况:
- 在心力衰竭 (HF) 中持续的拥堵与患者的不良结果有关.
- 生物阻抗分析 (BIA) 是一种非侵入性工具,用于评估急性HF的流体状况.
- 在HF门诊患者中检测亚临床拥堵的BIA的实用性仍未得到充分探索.
研究的目的:
- 调查心力衰竭与减少喷射率 (HFrEF) 的门诊患者中亚临床拥堵的患病率.
- 评估由BIA确定的亚临床拥堵与不良临床结果之间的关联.
- 探索BIA衍生流体状况标志物与已建立的HF生物标志物和患者特征的相关性.
主要方法:
- 一项前性,单中心研究招募了83名HFrEF门诊患者.
- 细分多频BIA评估了身体组成和细胞外水与全体水的比率 (ECW/TBW).
- 亚临床拥堵被定义为ECW/TBWz-score>2没有临床症状;主要结局是全因死亡或恶化HF.
主要成果:
- 57%的患者表现出亚临床拥堵,与年龄较大,女性性别和并发症有关.
- 较高的ECW/TBWz分数与较高的NT-proBNP水平和较低的肌肉质量相关.
- 亚临床和临床拥堵独立预测不良事件 (HR 9.4和17分别);ECW/TBW z-score和NT-proBNP具有相似的预测能力.
结论:
- 生物阻抗分析有效地识别了HFrEF门诊患者的亚临床拥堵,这是一个普遍的疾病.
- 通过BIA检测到的ECW/TBW比率升高与拥堵标志物相关,并预测不良结果.

39
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.

59
Heart failure (HF) manifests primarily as dyspnea, fatigue, and fluid retention, resulting in peripheral and pulmonary edema. Symptoms may vary depending on which ventricle is more affected, left or right.Left-Sided Heart FailureAlso known as left ventricular failure, this condition results from the left ventricle's inability to fill or eject sufficient blood into the systemic circulation. It leads to pulmonary congestion, which occurs when the left ventricle fails to eject blood effectively...

43
Heart failure can be classified in various ways, with the most common classifications based on physical activity limitations, disease progression, severity, and treatment strategies.The Functional Classification of Heart Failure divides patients into four categories based on physical activity limitation due to symptom burden.Class I: Patients in this class have cardiac disease but no physical activity limitations. Ordinary activities like walking, climbing stairs, or routine tasks do not cause...

01:27Heart Failure I: Introduction
77
Heart failure refers to a clinical syndrome caused by structural or functional cardiac disorders that prevent the heart from pumping an adequate amount of blood to meet the body's metabolic needs. This condition often arises from myocardial infarction or ischemia, leading to decreased cardiac output, reduced tissue perfusion, impaired gas exchange, fluid volume imbalance, and decreased functional ability.Heart failure can result from disruptions in the mechanisms that regulate cardiac output...

Diagnosing acute coronary syndrome or ACS begins with a thorough patient history. Notable symptoms include central, crushing chest pain radiating to the left arm, neck, jaw, or back, along with shortness of breath, sweating (diaphoresis), nausea, vomiting, dizziness, and palpitations.It is crucial to note any history of cardiac illnesses and assess risk factors, including age, gender, smoking, hypertension, diabetes, hyperlipidemia, and a sedentary lifestyle.During physical examination, vital...
