概括
作为心房心脏病的标志物,N-终端亲脑尿 (NT-pro BNP) 水平改善了超越传统血管风险因素的痴呆风险预测. 这有助于在心房动发作之前早期查和预防痴呆症.
科学领域:
- 心脏病学 心脏病学
- 神经学 神经学
- 生物标志物 生物标志物
背景情况:
- 心房动 (AF) 是一种与痴呆症相关的常见心律失常.
- 以心房重塑为特征的心房心脏病,与痴呆症独立相关,即使没有AF.
- 现有的痴呆风险模型可能无法完全捕捉AF相关的风险.
研究的目的:
- 开发和验证一种结合心房心脏病标志物的痴呆风险预测模型.
- 评估心房心脏病标志物的附加值与传统的血管风险因素 (CHA2DS2-VASc) 相比.
- 在亚临床心房变化的背景下探索痴呆风险预测.
主要方法:
- 利用了3,608名心血管健康研究 (CHS) 参与者的MRI和认知测试 (1992-1994) 的数据.
- 包括左心房心脏病的标志物:左心房维度,p波终端在V1 (PTFV1) 和N-终端亲脑尿 (NT-pro BNP).
- 根据TRIPOD指导方针开发了预测模型,比较了带有和没有心房心脏病标志物的模型.
主要成果:
- 在7.6年的随访期间,322名参与者患上了痴呆症.
- 较高的NT-pro BNP水平与累计痴呆发病率的增加相关.
- 与CHA2DS2-VASc相比,NT-pro BNP和PTFV1改善了痴呆症预测模型的适应性,特别是在女性中;与CHA2DS2-VASc相比,NT-pro BNP改善了男性的适应性.
结论:
- 与单独的CHA2DS2-VASc得分相比,NT-pro BNP水平可以提高痴呆风险预测.
- 这些发现支持NT-pro BNP作为在痴呆风险评估中对心房心脏病的有价值指标.
- 这些结果表明,早期痴呆症查和预防策略有可能针对AF诊断前的亚临床心房变化.

Blood Studies for Cardiovascular System I: Cardiac Biomarkers
749
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
516
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...
