概括
CHA2DS2-VASc评分预测了脱偿性心力衰竭的长期死亡率与保存的喷射分数 (HFpEF). 较高的得分表明这些患者的死亡风险增加.
科学领域:
- 心脏病学 心脏病学
- 心脏衰竭研究研究
- 预测生物标志物 预测生物标志物
背景情况:
- 脱偿心力衰竭与保留喷射分数 (HFpEF) 的死亡率很高.
- 最初用于心房动的CHA2DS2-VASc得分,在其他疾病中显示出预后价值,包括HF.
- 它在HFpEF死亡率中的作用需要进一步研究.
研究的目的:
- 根据他们的CHA2DS2-VASc得分,分析了无补偿HFpEF患者的长期死亡率.
- 确定CHA2DS2-VASc得分是否是该患者群体死亡率的独立预测指标.
主要方法:
- 从小波兰克拉科维亚心力衰竭 (LECRA-HF) 登记处 (2009-2022) 分析数据.
- 包括261名没有补偿的HFpEF患者.
- 将患者分为CHA2DS2-VASc得分组 (≥4比<4) 的分层和长期死亡率随访.
主要成果:
- 患有CHA2DS2-VASc评分≥4的患者年龄较大,主要是女性,并且患有更多的并发症,如心房动和之前的心脏干预.
- 这一组也表现出较低的GFR,,血红蛋白和血红素.
- 在CHA2DS2-VASc ≥4组 (P=0.005) 中,长期死亡率明显较高.
- CHA2DS2-VASc评分≥4是死亡率的独立预测指标 (HR 3.54).
- 在CHA2DS2-VASc得分上每增加1个点,所有原因的死亡风险都会增加32%.
结论:
- 该CHA2DS2-VASc得分作为一个独立的预后参数在失补偿的HFpEF.
- 这一发现突显了得分的实用性,超出了HFpEF患者风险分层的最初指示.

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...

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...

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...

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 (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...
