Blood Studies for Cardiovascular System I: Cardiac Biomarkers01:20

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...

科学领域:

  • 神经成像是一种神经成像.
  • 生物标志物 生物标志物
  • 老年学是一门学科.

背景情况:

  • 来自MRI的大脑年龄钟是大脑健康的宝贵生物标志物.
  • 目前的时钟在不同的人群中应用有限.
  • 这项研究评估了拉丁裔队列中的MRI衍生时钟,因为神经疾病的发病率很高.

研究的目的:

  • 使用拉丁裔队列的神经成像数据计算和评估简单完全卷积网络回归变体 (SFCN-reg) 的MRI衍生生物钟.
  • 评估SFCN-reg时钟在老年拉丁裔人的时间年龄和认知功能方面的表现.

主要方法:

  • 分析了125名老拉丁裔 (平均年龄74岁) 的结构神经成像和认知数据.
  • 计算了SFCN-reg时钟,并开发了一个微调版本.
  • 使用线性混合效应模型检查了与时间年龄的相关性以及与全球和特定领域认知得分的关联.

主要成果:

  • SFCN-reg时钟与时间年龄有很强的相关性 (原始的r=0.73,微调的r=0.70).
  • 增加SFCN-reg大脑年龄与降低的全球认知得分有关.
  • 两个时钟版本都预测了随着时间的推移更快的认知衰退.

结论:

  • SFCN-reg脑年龄钟在老拉丁裔队列中表现良好,与年龄和认知相关.
  • 这些时钟显示出在拉丁裔人口中作为大脑健康的生物标志物的潜力.
  • 建议对更大的拉丁裔样本进行进一步的研究,以验证这些发现.
