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:

  • 神经学 神经学
  • 遗传学 是一个遗传学.
  • 公共卫生 公共卫生

背景情况:

  • 认知能力下降受到年龄,教育和血管风险因素的影响,如高血压 (HTN),高脂血症 (HLD) 和糖尿病 (DM).
  • 阿波利波蛋白E4 (ApoE4) 是晚发性阿尔茨海默病的一个重要遗传风险因素.
  • 在认知障碍中,血管健康和遗传倾向 (ApoE4) 之间的相互作用需要进一步研究.

研究的目的:

  • 检查血管风险因素负担与非痴呆症队列中的认知功能之间的关联.
  • 研究个体血管风险因素和ApoE4状态对认知衰退的影响.
  • 探索血管风险因素和ApoE4对不同年龄组认知障碍的相互作用影响.

主要方法:

  • 从BIOCIS队列中评估了838名非痴呆症参与者.
  • 参与者按血管风险负担 (无,一,多) 和年龄组 (中年,晚年) 分层.
  • 用全球测试 (MoCA,VCAT) 和神经心理评估 (情节性记忆,执行功能,处理速度,视觉空间功能,语义流) 评估认知功能. 确定了血管风险因素和ApoE4状态.

主要成果:

  • 血管风险负担增加与年龄较大,教育程度较低以及所有领域的认知表现较差相关.
  • 超脂血症 (HLD) 和糖尿病 (DM) 显著增加了晚年轻度认知障碍 (MCI) 的几率.
  • 在中年,高血压 (HTN) 和ApoE4之间的相互作用显著增加了主观认知衰退 (SCD) 和MCI的风险.

结论:

  • 较高的血管风险因素数量与认知障碍的风险增加有关.
  • 虽然单独HTN并没有直接影响认知分类,但其与ApoE4的结合大大增加了中年认知障碍的风险.
  • 建议对ApoE4载体进行高血压的积极管理,以减轻认知能力下降的进展.
