Blood Studies for Cardiovascular System II: CRP, Hcy, and Cardiac Natriuretic Peptide Markers01:19

Blood Studies for Cardiovascular System II: CRP, Hcy, and Cardiac Natriuretic Peptide Markers

74
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...

Blood Studies for Cardiovascular System I: Cardiac Biomarkers

134
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 III: Serum Lipid Profile

152
Understanding serum lipids is crucial for maintaining cardiovascular health and preventing heart disease and stroke.
Serum lipids are fats and fatty substances in the blood and are crucial for various bodily functions, including energy storage, cellular structure, and hormone production. Serum lipids consist of cholesterol, triglycerides, and phospholipids.
Cholesterol is a soft, fat-like substance found in all body cells. It is crucial for producing hormones, vitamin D, and substances that aid...

  • 在急性冠状动脉综合征 (ACS) 中Lp(a) 的特定作用需要进一步澄清.

研究的目的:

  • 测试Lp (a) 水平是否在ACS急性阶段发生变化.
  • 确定这些变化是否与随后的心血管事件相关.

主要方法:

  • 分析了377名接受冠状动脉血管造影的ACS患者.
  • 在皮肤冠状动脉干预 (PCI) 之前和之后的48小时内测量了Lp (a) 水平.
  • 主要不良心脏事件 (MACE) 被追踪了平均1000天.

主要成果:

  • 在PCI后12小时,Lp (a) 水平显著下降,然后在48小时后上升.
  • Lp(a) 降低的幅度与基线肌素和Lp(a) 水平相关.
  • 更大的Lp (a) 降低与更高的MACE率有关.

结论:
