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

769
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:

  • 心血管科学 心血管科学
  • 营养生物化学 营养生物化学
  • 生物标志物研究 生物标志物研究

背景情况:

  • 欧米茄-3脂肪酸 (FA) 可能降低心肌梗塞突然死亡风险.
  • 心肌细胞中EPA和DHA的结合会影响离子通道的功能.
  • 人类心脏omega-3FA结合水平仍未确定.

研究的目的:

  • 为了确定心脏和红细胞 (RBC) 欧米茄-3 FA水平在人类之间的相关性.
  • 为了检查omega-3FA补充剂对FA组成在各种人体组织中的影响.
  • 确定一个可靠的替代品来评估心脏omega-3FA状态.

主要方法:

  • 在20名心脏移植接受者的心脏和RBComega-3FA水平之间的相关性分析.
  • 对25名患者的心脏,口腔,红血细胞和血的FA组成对omega-3FA补充 (1g/天6个月) 的影响的评估.
  • 在心脏组织,红细胞,血和口腔细胞中分析FA水平.

主要成果:

  • 心脏和红血球中的eicosapentaenoic acid (EPA) + docosahexaenoic acid (DHA) 水平显示出强烈的相关性 (r=0.82,P<0.001).
  • 六个月的omega-3FA补充剂显著增加了心脏组织 (110%),红细胞 (101%),血 (139%) 和口腔细胞 (73%) 的EPA+DHA水平.
  • 在所有测量组织中,EPA+DHA水平的百分比增加是可比的.

结论:

  • 红细胞 (RBC) 的EPA+DHA水平与心脏的EPA+DHA含量有很强的相关性.
  • 红细胞是监测心脏omega-3FA状态的合适替代体,因为其易于收集,分析和稳定的FA组成.
  • 欧米茄-3指数 (RBC EPA+DHA) 可能是心脏欧米茄-3 FA状态的首选生物标志物.
