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:

  • 神经科学是一个神经科学.
  • 免疫学 免疫学 免疫学
  • 遗传学 是一个遗传学.

背景情况:

  • 周围炎症是阿尔茨海默病 (AD) 发展和进展的已知危险因素.
  • 衰老会增加炎症,可能是AD发病之前的.
  • 父母患有阿尔茨海默氏症的病史会增加一个人患这种疾病的终身风险.

研究的目的:

  • 为了调查父母患有阿尔茨海默氏症的病史是否与中年成人外周炎症的增加有关.
  • 为了确定患有阿尔茨海默氏症父母史的个体与没有阿尔茨海默氏症的个体相比,表现出更高水平的促炎细胞因子.
  • 检查这些协会跨越不同的种族和种族群体.

主要方法:

  • 分析了1043名非西班牙裔白人,非西班牙裔黑人和西班牙裔成年人的后代研究.
  • 通过诊断共识会议来确定父母的AD状态.
  • 使用Luminex技术测量血化基因和细胞因子度,并根据年龄,性别,种族,种族和APOE基因型进行调整.

主要成果:

  • 患有阿尔茨海默氏病父母病史的参与者表现出较高的Eotaxin水平和较低的G-CSF,VEGF-A和IL-27.
  • 观察到的特定差异:黑人个体的IL-18高,白人个体的EGF高,父母有AD史.
  • 患有阿尔茨海默氏病的父母有过阿尔茨海默氏病史的妇女,IFna2,IL-12p70,sCD40L和IL-18的水平较高.

结论:

  • 父母患有阿尔茨海默病的病史与周围炎症标志物升高有关.
  • 观察到的父母阿尔茨海默病史和炎症之间的关联因性别和种族/种族而异.
