概括
在急性冠状动脉综合征 (ACS) 后,早期评估心力衰竭 (HF) 风险至关重要. 第1天的S100A8/A9水平有效预测HF风险,有助于患者分层和指导治疗决策.
科学领域:
- 心脏病学 心脏病学
- 生物标志物 生物标志物
- 急性冠状动脉综合征研究研究
背景情况:
- 在急性冠状动脉综合征 (ACS) 患者中早期心力衰竭 (HF) 风险评估可以降低死亡率.
- 在心肌缺血期间释放的标记物S100A8/A9,参与反损伤,是ACS后HF的关键预测因子.
- 基于动态S100A8/A9变化的可靠HF风险分层工具的开发对于ACS患者进行再输血后治疗至关重要.
研究的目的:
- 构建和验证心力衰竭 (HF) 风险分层的可靠工具,用于重灌治疗后急性冠状动脉综合征 (ACS) 患者.
- 评估S100A8 / A9水平对HF发展的动态变化的预测值.
- 评估β-阻断剂治疗对不同风险群体中HF事件的影响.
主要方法:
- 这是一项前性研究,涉及3个独立的ACS患者队列,这些患者正在接受再注射治疗.
- 血清S100A8/A9水平在发现队列的不同时间点 (入院,第1至第4天) 和验证队列的第1天被测量.
- 追踪HF事件 (住院和长期) 的中位数随访时间为1.8至4.2年.
主要成果:
- 在入院后的第1天测量的S100A8/A9水平显示,与其他时间点相比,HF的预测能力更强.
- 在第一天使用S100A8/A9的风险分层模型确定了高风险患者 (>7900 ng/mL),其1年HF事件率 (46-38%) 与低风险患者 (<2100 ng/mL) (2-5%) 相比显著更高.
- 在没有ACS后的左心室功能障碍的患者中,β-阻断剂治疗在中高风险组中减少了1年的HF事件,但在低风险组中没有.
结论:
- 在ACS后的第1天测量出的血清S100A8/A9水平可靠地根据患心力衰竭的风险对患者进行分类.
- 这种生物标志物作为HF风险预测的强大工具,可以指导治疗干预.
- 这些发现支持使用S100A8 / A9作为个性化风险评估和管理在ACS患者的动态标记.

Blood Studies for Cardiovascular System I: Cardiac Biomarkers
86
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...

Blood Studies for Cardiovascular System II: CRP, Hcy, and Cardiac Natriuretic Peptide Markers

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...
