概括
脂蛋白 (Lp) 比LDL-C等传统脂质更稳定. 虽然非常高或很低的Lp (a) 水平保持一致,但中间水平可能需要重新测试以进行准确的心血管风险评估.
科学领域:
- 心脏病学 心脏病学
- 临床脂质学 临床脂质学
- 预防医学 预防医学
背景情况:
- 脂蛋白 (Lp) 是一种基因决定的心血管风险因素.
- 有限的数据存在Lp(a) 类别随着时间的推移重新分类,特别是在东亚人口中.
- 了解Lp(a) 稳定性对于心血管风险分层至关重要.
研究的目的:
- 评估Lp (a) 水平的个体内稳定性和重新分类率随时间推移.
- 将Lp的稳定性与传统的脂质标记物 (LDL-C,ApoB,甘油三) 的稳定性进行比较.
- 评估监测心血管风险的临床影响.
主要方法:
- 对230,018名韩国成年人进行了回顾性队列研究,其中至少有两次Lp (a) 测量.
- 排除以前患有冠状动脉疾病或降脂治疗的个人.
- 在预定义的Lp (a) 类 (<30,30-50,50-100,≥100 mg/dL) 中分析类内相关系数 (ICC) 和重新分类率.
主要成果:
- Lp(a) 显示出极好的可重复性 (ICC ≥0.99),在稳定性方面超过了LDL-C,ApoB和甘油三.
- 91-93%的参与者在非常低的 (<30 mg/dL) 或非常高的 (≥100 mg/dL) 水平方面仍然处于他们的基线Lp (a) 类别.
- 在中间的Lp (a) 范围发生了显著的重新分类 (30-50 mg/dL: 35%的风险更高; 50-100 mg/dL: 19%的风险更高).
结论:
- 与传统的脂质标记物相比,Lp (a) 的长期稳定性更高.
- 对于具有非常低或非常高水平的个体,单个Lp (a) 测量可能足够.
- 对于那些中等水平 (30-100 mg/dL) 的人来说,建议定期重新评估Lp (a),以完善心血管风险评估.

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...

Cholesterol: Significance and Regulation
1.2K
Although not a source of energy, cholesterol plays a significant role as a foundational structure for bile salts, steroid hormones, and vitamin D, as well as being a crucial component of plasma membranes. Approximately 15% of blood cholesterol is derived from our diet, with the remainder synthesized from acetyl CoA by the liver and intestines. Cholesterol is eliminated from the body through its conversion into bile salts, which are eventually discarded in the feces.
Considering cholesterol and...

Lipid metabolism is a crucial process in the human body that involves the synthesis and degradation of lipids. This process is essential for energy production, cell membrane formation, and hormone production, among other functions.
Lipolysis: The Breakdown of Lipids:
Lipolysis is the process of breaking down lipids, particularly triglycerides, into glycerol and fatty acids. This process typically occurs in the adipose tissue and is triggered by various hormones, including glucagon and...

Lipid-derived Compounds in the Human Body
6.2K
Fats and lipids are crucial components in the human body. Some lipid-derived compounds, such as fat-soluble vitamins, eicosanoids, lipoproteins, and glycolipids, also play unique roles to support various biological processes .
Fat-soluble Vitamins
Fat-soluble vitamins, including vitamins A, D, E, and K, are required in minimal quantities, but their deficiencies can lead to severely abnormal physiological conditions. For example, vitamin A deficiency can cause night blindness, dry skin,...

Lipid Absorption
2.4K
Dietary triglycerides from chyme in the duodenum are mixed with bile salts produced by the liver to emulsify fats. As a result, large droplets are broken down into smaller ones, increasing the surface area for enzymatic action. Once emulsified, pancreatic lipases hydrolyze the triglycerides into free fatty acids and monoglycerides.
These breakdown products bind with bile salts and lecithin to form micelles, which quickly pass between microvilli to come in close contact with the apical...

Longitudinal Research
13.1K
Sometimes we want to see how people change over time, as in studies of human development and lifespan. When we test the same group of individuals repeatedly over an extended period of time, we are conducting longitudinal research. Longitudinal research is a research design in which data-gathering is administered repeatedly over an extended period of time. For example, we may survey a group of individuals about their dietary habits at age 20, retest them a decade later at age 30, and then again...
