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...

科学分野:

  • 神経学
  • バイオマーカー研究
  • 神経画像

背景:

  • アルツハイマー病（AD）のバイオマーカー（血液p-Tau、タウPET、アミロイドPETなど）はAD病理を予測する。
  • 神経炎症マーカーGFAPおよびNfLも重要である。
  • 軽度認知機能障害（MCI）および軽度認知症における短期的な低下に対するそれらの予測可能性は、さらに探求する必要がある。

主な方法:

  • タイのバンコクにある記憶クリニックからMCIおよび軽度認知症の参加者を募集した。
  • ベースラインでタウPET、アミロイドPET、血漿p-Tau-181、p-Tau-217、GFAP、およびNfLを評価した。
  • スコア変化に基づいて進行群を定義し、ベースラインおよび24ヶ月のフォローアップでMoCAおよびCDR-SBを使用して認知および機能能力を評価した。

結論:

  • Braakステージ3-4のタウPET SUVRは、短期的な認知および機能低下の強力な予測因子である。
  • 血漿p-Tau-217は、診断的および予後的有用性の両方を示す。
  • 血漿GFAPは、このコホートにおける短期的な進行の予測において、血漿NfLよりも効果的である。
