概括
中性粒细胞外细胞陷 (NET) 标记核细胞素化组织素H3 (H3Cit-DNA) 并没有预测ST升高心肌梗塞 (STEMI) 患者的不良事件. 经典的炎症标志物C-反应蛋白 (CRP) 和互白素-6 (IL-6) 改善了30天的风险预测.
科学领域:
- 心血管医学 心血管医学
- 免疫学 免疫学 免疫学
- 生物标志物发现发现
背景情况:
- 炎症是ST升高心肌梗塞 (STEMI) 病理生理学的核心.
- 中性粒细胞外细胞陷 (NETs) 和它们的组成部分与STEMI预后有关.
- 具体流通的NET标记物的预后价值仍然不清楚.
研究的目的:
- 评估核细胞素基因组H3 (H3Cit-DNA),一种NET特异性标记物,用于预测STEMI后的不良事件.
- 为了比较H3Cit-DNA与经典炎症标记物的预测效用.
主要方法:
- 在487名接受初级穿皮冠状动脉干预 (PCI) 的STEMI患者进行了回顾性队列研究.
- 在入院时分析血清H3Cit-DNA,双链DNA,IL-6,IL-1β,TNF-α和CRP水平.
- 与主要不良心血管事件 (MACE) 的关联,包括死亡,心脏复发,紧急再血管化和心力衰竭.
主要成果:
- H3Cit-DNA水平与30天死亡率,MACE,Killip类或左心室喷射分数无关.
- 当被添加到临床风险模型中时,C-反应蛋白 (CRP) 和白蛋白-6 (IL-6) 水平显著改善了30天MACE的预测.
结论:
- 在STEMI的早期阶段,循环的H3Cit-DNA不是心血管事件的有用预测因素.
- 经典的炎症标志物CRP和IL-6在STEMI中具有显著的预后价值.
- 特定于NET的标记物在评估STEMI早期炎症状态时可能具有有限的效用.

71
Cardiac biomarkers are enzymes, proteins, and hormones released into the blood when cardiac cells are injured. They are powerful tools for triaging.
The essential diagnostic tools for detecting myocardial necrosis and monitoring individuals suspected of having acute coronary syndrome (ACS) include:
Troponins
Troponins, particularly cardiac troponins I and T, are the most precise and sensitive markers of myocardial injury. They are detectable within 4-6 hours of myocardial injury and remain...

Cardiac biomarkers are critical in diagnosing, prognosing, and managing cardiovascular diseases. Routine measurement of specific biomarkers such as B-type natriuretic peptide (BNP), C-reactive protein (CRP), and homocysteine (Hcy) is common practice in clinical settings to evaluate heart function and predict cardiovascular events.
These markers indicate stress or strain on the heart muscle:
Natriuretic Peptides (BNP)
Cardiac myocytes produce these hormones in response to ventricular stretching...
