概括
心力衰竭患者的突然心脏死亡 (SCD) 风险可能不会像人们普遍认为的那样下降. 这篇评论质疑SCD的感知下降,并主张在高压治疗中继续使用可植入心脏转换器除器.
科学领域:
- 心脏病学
- 心脏衰竭的研究
- 突发心脏病死亡研究
背景情况:
- 人们越来越相信,心力衰竭患者接受指导性治疗 (GDMT) 时,突然心脏死亡 (SCD) 的风险正在降低.
- 编辑建议不律性SCD不再对接受GDMT的HF患者构成重大威胁.
研究的目的:
- 在HF试验和现实环境中批判性地评估SCD风险是否真正下降.
- 评估残留SCD风险是否可以在GDMT的情况下继续使用可植入心脏转动器 (ICD).
- 检查HF试验结果在临床实践中的应用.
主要方法:
- 对心力衰竭临床试验现有数据的审查.
- 对SCD发病率的现实证据的分析.
- 对HF的GDMT和器械治疗研究的批判性评估.
主要成果:
- 证据表明SCD在HF试验或实际人群中没有下降.
- 不遵循指导器械治疗 (GDDT) 的试验数据不足以延迟ICD植入.
- 在将高频率试验结果应用于各种现实患者群体时存在挑战.
结论:
- 在HF患者中感知到的SCD风险下降可能是不准确的.
- ICD治疗对于慢性HF的残留SCD风险的管理至关重要.
- 未来的HF试验应纳入GDDT以更好地定义ICD的作用.

Pathophysiology of Heart Failure
1.7K
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...

Heart Failure Drugs: β-Blockers
411
β-adrenergic antagonists, commonly known as β-blockers, block the effects of sympathetic neurotransmitters such as noradrenaline (NA) and adrenaline (ADR). They have several beneficial effects in heart failure treatment. They reduce heart rate, the force of contraction, and cardiac muscle relaxation. They also slow the atrial-ventricular conduction rate and raise the threshold for arrhythmias. The concentration of β-blockers determines their effects on bronchodilation,...

Heart Failure I: Introduction
30
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...

Imbalances in Cardiac Output
1.4K
The heart's primary function is to pump blood throughout the body, maintaining a balance between blood sent out (cardiac output) and blood returning (venous return). If this balance is disrupted, it can result in congestive heart failure (CHF), a severe condition where the heart becomes an inefficient pump, leading to inadequate blood circulation.
CHF can occur due to the failure of either side of the heart. Left-side failure leads to pulmonary congestion—the right side continues to send...

The first step in nursing management of a patient with heart failure involves thoroughly assessing the patient's medical history.Subjective Data: Obtain the patient's medical history of coronary artery disease, hypertension, myocardial infarction, and symptoms like dyspnea, orthopnea, and paroxysmal nocturnal dyspnea.Objective Data: Conduct a physical examination to identify findings such as jugular vein distention, pulmonary crackles, tachycardia, murmurs, peripheral edema, and vital signs,...
