Blood Studies for Cardiovascular System I: Cardiac Biomarkers01:20

Blood Studies for Cardiovascular System I: Cardiac Biomarkers

746
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

511
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:

  • 神经学 神经学
  • 老年学是一门学科.
  • 生物标志物 生物标志物

背景情况:

  • 感官和身体功能下降与阿尔茨海默氏症和相关痴呆症 (ADRD) 的风险增加有关.
  • 关于感官/身体功能,ADRD生物标志物和年轻和中年成年人的认知之间的联系的研究有限.

研究的目的:

  • 调查感觉和身体功能,ADRD大脑脊髓液 (CSF) 生物标志物和认知功能之间的关联.
  • 在跨越广泛年龄段的成年人队列中检查这些关系.

主要方法:

  • 利用杜克-UNC ADRC的243名参与者的数据,其中162人正在接受CSF生物标志物评估.
  • 评估视觉 (视觉敏度测试),听觉 (QuickSIN,听力测量) 和身体功能 (握力,上下测试).
  • 用于认知领域 (执行,语言,视觉空间功能 - ELVF;记忆) 的因素分析和一般线性模型来分析关联,控制共变量.

主要成果:

  • 更好的听力和视力与改善的记忆和ELVF认知表现相关.
  • 提高听力与更高的Aβ42/40比率和更低的p-tau181水平有关.
  • 改善的步行速度与更好的记忆和ELVF,更高的Aβ42/40和更低的NfL相关. 更好的握力与改善的ELVF相关.

结论:

  • 感官和身体功能与认知功能和ADRD生物标志物有关,跨越各种成人年龄.
  • 这些关系似乎独立于人口和临床因素.
  • 建议在更大,更多样化的队列中进行进一步的复制,以确认发现并探索特定年龄的影响.
