概括
在人类心肌梗塞后的左心室逆转型中,阿佩利纳基系统,特别是阿佩林-17,可能起作用. 较高的阿佩林-17水平独立地与这种心脏病发作后并发症有关.
科学领域:
- 心脏病学 心脏病学
- 生物化学 生物化学
- 生理学 生理学 生理学
背景情况:
- 动物模型表明,辅激系统在心肌梗塞期间保护心脏.
- 人类心肌梗塞后左心室重塑中阿佩利内尔基系统的作用尚不清楚.
研究的目的:
- 研究人类ST段升高心肌梗塞后的阿比利内尔基系统和左心室逆向重塑之间的关联.
主要方法:
- 研究了49名前部ST升高心肌梗塞患者.
- 心声检查评估了左心室重塑 (增加LV终端透析体积>20%) 在基线和一年.
- 在一年的随访中测量了阿佩林 (ELA,AP-17,AP-13) 和APJ受体的血水平.
主要成果:
- 患有不良左心室重塑的患者血中阿佩林-13和阿佩林-17.的水平显著更高.
- 无变量分析显示,不良改造与更高的LVEDV,LVESV,WMSI,SYNTAX得分,hs-CRP,AP-13和AP-17之间存在关联.
- 多变量分析确定AP-17水平是不利的左心室重塑的独立预测因素 (p=0.050).
结论:
- 阿佩利纳基系统,特别是阿佩林-17,可能与心肌梗塞后左心室重塑不良的发展有关.
- 需要进一步研究以阐明涉及的具体机制.

01:26Heart Failure Drugs: Inhibitors of Renin-Angiotensin System
302
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 (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...
