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.
  • 神经学 神经学
  • 药理学 药理学是指药理学的学科.

背景情况:

  • 阿尔茨海默病 (AD) 诊断依赖于成像工具,如基于Voxel的特定区域分析 (VSRAD).
  • 评估结构性大脑变化对于了解AD进展和治疗疗效至关重要.
  • 莱卡尼马布是一种新兴的AD治疗药物.

研究的目的:

  • 为了评估lecanemab对大脑缩的影响,特别是海马体和整体大脑体积.
  • 利用VSRAD成像测量可能患有AD的患者的这些变化.

主要方法:
