概括
脂蛋白 (a) 水平独立于低密度脂蛋白胆固醇和非高密度脂蛋白胆固醇. 单独测量脂蛋白 (a) 对于评估高胆固醇血症患者的动脉样硬化风险至关重要.
科学领域:
- 心血管医学 心血管医学
- 脂质学 脂质学是指脂质学.
- 遗传学 遗传学 是一个
背景情况:
- 低密度脂蛋白 (LDL) 和脂蛋白 (Lp) 是含有阿波利波蛋白B的益风原性颗粒.
- 升高的LDL胆固醇 (C),非HDL-C和apo B的特征是异构性家族性高胆固醇血症 (HeFH),但Lp (a) 水平的报道不一致.
研究的目的:
- 在高胆固醇血症患者中研究血Lp (a) 和LDL-C,非HDL-C和apo B水平之间的关系.
- 为了确定Lp (a) 水平是否在基因确诊的HeFH患者中升高.
主要方法:
- 对256名具有遗传特征的高胆固醇血症患者和272名对照患者的回顾性图表审查.
- 对血Lp (a) 和LDL-C,非HDL-C和ApoB水平之间的对对相关性的分析.
主要成果:
- 在高胆固醇血症患者和对照人群中,Lp (a) 的平均水平没有差异.
- 在两组中都没有发现Lp(a) 与LDL-C或非HDL-C之间的显著相关性.
- 在患者 (r=0.103,P=0.112) 和对照组 (r=0.175,P=0.005) 中观察到Lp(a) 和apo B之间存在弱相关性.
结论:
- Lp (a) 水平独立于LDL-C和非HDL-C,并且在HeFH患者中没有升高.
- Apo B 仅与 Lp 的联系较弱.
- 必须单独测量Lp (a),以评估其对高胆固醇血清症动脉样硬化风险的影响,因为它不能从LDL-C中预测.

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...

Cholesterol: Significance and Regulation
548
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.

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...

Lipids: Dietary Sources and Requirements
741
Lipids are an essential component of a balanced human diet. Triglycerides, which make up the majority of dietary lipids, are found in both saturated fats—commonly present in meat, dairy products, and certain tropical plants like coconut, and hydrogenated oils such as margarine and baking shortenings (trans fats)—and unsaturated fats, which are abundant in seeds, nuts, olive oil, and most vegetable oils. The main sources of cholesterol include egg yolks, various meats and organ...

Lipid Absorption
475
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...

Lipids also are sources of energy that power cellular processes. Like carbohydrates, lipids are composed of carbon, hydrogen, and oxygen, but these atoms are arranged differently. Most lipids are nonpolar and hydrophobic. Major types include fats and oils, waxes, phospholipids, and steroids.
Fatty acids are catabolized in a process called beta-oxidation, which takes place in the matrix of the mitochondria and converts their fatty acid chains into two-carbon units of acetyl groups. The acetyl...
