概括
升高的脂蛋白 (Lp) 是动脉样硬化心血管疾病 (ASCVD) 的重要危险因素. 高Lp(a) 水平与较早的ASCVD发病相关,正常的LDL-C并不排除高Lp(a).
科学领域:
- 心脏病学 心脏病学
- 遗传学 是一个遗传学.
- 生物化学 生物化学
背景情况:
- 血脂蛋白 (Lp) 的升高是动脉样硬化心血管疾病 (ASCVD) 的流行,因果风险因素.
- Lp(a) 可能显著影响血低密度脂蛋白胆固醇 (LDL-C) 水平.
- 了解Lp(a) 和LDL-C之间的关系对于评估心血管风险至关重要.
研究的目的:
- 通过不同的Lp (a) 水平来表征临床特征.
- 评估LDL-C水平是否可靠地表明潜在的升高Lp.
- 为了确定在不同Lp (a) 度下正常或升高的LDL-C的个体比例.
主要方法:
- 追溯性研究设计.
- 从医疗记录和北丹麦地区临床实验室系统 (LABKA) I和II (2021年1月 - 2024年8月) 收集的数据.
- 包括1346名个人,详细的临床和生化数据.
主要成果:
- 28.5%的人患有升高的Lp (a) 水平 (≥125nmol/L).
- 在Lp (a) ≥400nmol/L的患者中,ASCVD的患病率为57.7%,而Lp (a) <100nmol/L的患者为21.1%.
- 平均ASCVD发病年龄为51岁,Lp (a) ≥400nmol/L,而Lp (a) <100nmol/L的年龄为56岁.
- 在Lp (a) ≥300nmol/L的个体中,7.6%的LDL-C<3.0mmol/L,9.1%的LDL-C在第一次测量时为3.0-3.5mmol/L.
- 增加Lp (a) 水平与ASCVD患病率增加和ASCVD发病年龄降低相关.
结论:
- 不同的临床特征与不同的Lp (a) 水平有关.
- 升高的Lp (a) 与ASCVD风险增加和早期发病有关.
- 正常的LDL-C水平不能排除高度升高的Lp的存在.

Blood Studies for Cardiovascular System III: Serum Lipid Profile

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...

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-Lowering Drugs: Statins and Miscellaneous Agents

Hyperlipidemia, a medical condition often referred to as high cholesterol, is characterized by abnormally elevated levels of lipids in the bloodstream. When present in excess, these lipids, specifically cholesterol and triglycerides, can lead to serious health complications, often involving cardiovascular diseases. Illnesses like atherosclerosis, heart attacks, and pancreatitis have all been linked to untreated hyperlipidemia. This means controlling and regulating cholesterol and triglyceride...

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...

Atherosclerosis I: Introduction
818
Atherosclerosis is a progressive disorder characterized by the buildup of plaques on the arterial inner wall, causing them to narrow and harden over time. These plaques comprise lipids, calcium, blood components, carbohydrates, and fibrous tissue. The process primarily affects the intima of large and medium-sized arteries, reducing blood flow in any artery.Etiology and risk factorsThe cause of atherosclerosis is multifactorial, involving a complex interplay among endothelial injury, lipid...

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.
