概括
在心力衰竭患者中,虚弱和代谢脆弱性指数 (MVX) 之间的联系很弱. 两者都独立地预测死亡风险,表明它们评估了脆弱性的不同方面.
科学领域:
- 心脏病学 心脏病学
- 老年学是一门学科.
- 生物标志物发现发现
背景情况:
- 虚弱性在心力衰竭 (HF) 中普遍存在,并预测死亡率,但没有定期评估.
- 虚弱与炎症和营养不良有关,有可能通过代谢脆弱性指数 (MVX) 来衡量.
研究的目的:
- 在心力衰竭队列中评估脆弱性和MVX之间的关联.
- 为了确定脆弱性和MVX对死亡率的独立和联合预后影响.
主要方法:
- 使用赤字积累模型 (32项) 评估脆弱性.
- 通过核磁共振光谱学在985名高频患者中测量了MVX.
- 利用考克斯模型和Uno的C统计数据进行预后评估和调解分析.
主要成果:
- 脆弱性和MVX显示出弱相关性 (ρ=0.21).
- 较高的脆弱性独立预测死亡率增加 (HR 3.3),即使经过对临床因素进行调整 (MAGGIC评分,NT-proBNP).
- MVX显示了脆弱性与死亡率相关性的最小调解 (3.3-4.5%).
结论:
- 脆弱性和MVX是心力衰竭中的脆弱性的不同衡量标准.
- 脆弱性和MVX都独立地导致HF患者死亡风险分层.

Pathophysiology of Heart Failure
1.6K
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...

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...
