概括
大动脉狭窄 (AS) 在心力衰竭 (HF) 患者中很常见,甚至在轻微的情况下也会使结果恶化. 许多患有HF的严重AS患者没有及时接受大动脉置换,这表明有显著的治疗缺口.
科学领域:
- 心脏病学 心脏病学
- 心血管研究研究心血管研究
- 临床医学 临床医学
背景情况:
- 大动脉狭窄 (AS) 经常与心力衰竭 (HF) 一起存在.
- 整个高频谱的AS的患病率,预后影响和管理尚未完全理解.
- 了解这种关系对于改善患者治疗结果至关重要.
研究的目的:
- 为了调查AS在HF患者的患病率.
- 确定AS严重程度对HF患者预后结果的预后影响.
- 在HF的背景下评估AS的管理.
主要方法:
- 对22906名接受心声扫描的高风患者 (2010-2020年) 的回顾性队列研究.
- AS被分类为轻度,中度,低梯度 (LG) 或严重.
- 使用考克斯回归评估的结果,按HF亚型分层,并根据混因素进行调整. 主要终点:无事件生存率 (所有原因死亡率或AVR).
主要成果:
- 中度AS在5.5%,LGAS在2.5%,严重AS在6.5%的HF患者中.
- 增加AS严重程度与明显更糟糕的结果相关 (例如,严重AS HR 6.20).
- 这些关联在所有HF亚型中都是一致的;只有59.5%的严重AS患者在2年内获得AVR.
结论:
- AS在HF患者中普遍存在,并且与更糟糕的长期结果相关,即使在非严重的阶段.
- 在AS-HF患者中高死亡风险和不频繁的干预突显了治疗缺口.
- 需要进行前性试验,以评估HF中AS的早期干预策略.

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...

01:17Pathophysiology of Heart Failure
3.0K
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...

01:27Heart Failure I: Introduction
729
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...

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.

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...
