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...

  • 公共卫生 公共卫生

背景情况:

  • 脑卒中后认知障碍 (PSCI) 可以表现为早期或延迟.
  • 虽然早期PSCI是常见的,但延迟PSCI的发病率和风险因素仍然不太了解.

研究的目的:

  • 为了确定延迟发病PSCI的发生率.
  • 在急性脑梗塞患者中确定与延迟发作的PSCI相关的风险因素.

主要方法:

  • 197名患有急性脑梗塞且没有早期PSCI的患者被随访了24周.
  • 使用MoCA评估认知能力;根据既定标准诊断延迟PSCI.
  • 后勤回归和相关性分析确定了风险因素.

主要成果:

  • 延迟发作的PSCI的发生率为11.68%.
  • 在延迟PSCI组中观察到更高的NIH中风量表 (NHISS) 基线得分和更少的定期运动率.
  • 多变量分析显示,较高的基线NHISS得分 (OR=1.525) 和更多的脑血管疾病风险因素 (OR=2.904) 与延迟发作的PSCI显著相关.

结论:

  • 晚发性PSCI发生在11.68%的急性脑梗塞后患者中.
  • 基线NHISS得分升高和多重脑血管疾病风险因素是延迟发病PSCI的显著预测因素.
