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...

后皮层缩 (PCA) 和典型的阿尔茨海默病 (tAD) 与对照人群相比,显示眼血管曲性增加和分支复杂性减少. 与tAD相比,PCA表现出比tAD更多的扭曲和稀疏的眼血管,这表明在阿尔茨海默病检测中可能使用眼镜成像.

科学领域:

  • 眼科医生 眼科 眼科
  • 神经学 神经学
  • 血管生物学 血管生物学

背景情况:

  • 阿尔茨海默氏症 (AD) 呈现出不同的表型,包括典型的AD (tAD) 和后皮层缩 (PCA),血管变化不清楚的差异.
  • 视网膜微血管与大脑微循环有相似之处,使眼血管评估成为研究AD相关大脑变化的潜在替代品.
  • PCA是一种AD的变体,通常涉及视觉功能障碍,并且可能与tAD相比具有不同的血管病理.

研究的目的:

  • 为了比较PCA和tAD表型之间的眼血管变化.
  • 研究眼血管形态作为区分AD亚型的潜在生物标志物.
  • 探索眼睛微血管变化和AD中神经退行症之间的关系.

主要方法:

  • 预期招募AD患者 (Aß阳性) 和认知不受损 (CU) 控制 (Aß负).
  • 综合评估包括神经心理测试,神经成像和光学连贯性断层扫描血管学 (OCTA).
  • 使用自动化OCTA算法对视神经头部 (ONH) 和斑点中的血管曲度和分支复杂性的量化.

主要成果:

  • 与CU对照组相比,PCA和tAD组在ONH和斑点中显著增加了血管曲性和降低了分支复杂性.
  • 与tAD相比,PCA在ONH和斑点中显示出明显更大的血管扭曲性和不那么复杂的分支.
  • 在PCA和tAD组中,在ONH血管变化和中间叶缩之间发现了显著的相关性.
