概括
患有连续流动左心室辅助器件的患者中较高的N-终端脑前性尿素水平与增加的死亡率和心力衰竭住院病例有关. 序列评估可以指导这些患者的个性化护理.
科学领域:
- 心脏病学 心脏病学
- 生物标志物 生物标志物
- 医疗器械 医疗器械
背景情况:
- 尿酸是心力衰竭中确定的预后标志物.
- 持续流动的左心室辅助器件 (CF-LVADs) 用于心力衰竭患者.
- 在CF-LVAD患者中,N-终端前脑尿素 (NT-proBNP) 的预后值需要进一步评估.
研究的目的:
- 为了评估NT-proBNP水平和CF-LVADs患者的临床结果之间的关联.

The activation of the sympathetic nervous system and the renin-angiotensin-aldosterone system (RAAS) contributes to cardiac remodeling, and inhibiting the RAAS is a pharmacological target in heart failure management. As a result, neurohumoral modulation is a crucial treatment principle for managing heart failure. This approach involves using medications like ACE inhibitors (ACEIs), angiotensin receptor blockers (ARBs), β-blockers, mineralocorticoid receptor antagonists (MRAs), and neutral...

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...
