概括
LDL-C/ApoB比率是LDL颗粒大小的标志物,是老年人心血管事件 (CI) 的重要危险因素. 保持最佳比率可能对预防CI至关重要.
科学领域:
- 心血管医学 心血管医学
- 脂质代谢 脂质代谢是什么
- 老年人的健康 老年人的健康
背景情况:
- 升高的Apolipoprotein B (ApoB) 和LDL-C水平与心血管事件 (CI) 有关.
- LDL-C/ApoB比率表明LDL颗粒的大小;较小,更密集的LDL (sdLDL) 颗粒更具有异性.
- 确切的LDL-C/ApoB比率与CI之间的关系需要进一步阐明.
研究的目的:
- 研究60岁以上个体的LDL-C/ApoB比率与心血管事件 (CI) 之间的关联.
- 探索LDL-C/ApoB比率与CI之间的潜在非线性关系.
主要方法:
- 利用了2011-2014年国家健康和营养检查调查 (NHANES) 的数据.
- 包括1105名60岁以上的参与者.
- 使用后勤回归和限制立方线 (RCS) 分析.
主要成果:
- 后勤回归显示,LDL-C/ApoB比率与CI (OR:1.519,p < 0.001) 之间存在显著的关联,但不仅仅是ApoB (OR:1.003,p = 0.215).
- 在对年龄和性别进行调整后,这些发现仍然存在 (OR: 1.349,p < 0.05).
- RCS分析表明,即使在调整后,LDL-C/ApoB比率和CI (P非线性<0.0001) 之间存在显著的非线性关系.
结论:
- 确定LDL-C/ApoB比率是老年人群中CI的潜在风险因素.
- 一个最佳的LDL-C/ApoB比率可能在预防心血管事件中起到至关重要的作用.

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...
