概括
无脂蛋白B粒子计数准确地预测了冠状动脉疾病 (CAD) 风险,无论粒子类型或大小. 脂蛋白[Lp[a]水平为CAD提供了额外的,独立的风险信息.
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.
- 生物标志物 生物标志物
背景情况:
- 阿波利波蛋白B (apoB) 度是动脉质脂蛋白和冠状动脉疾病 (CAD) 风险的关键标志物.
- 对于CAD风险的apoB粒子 (apoB-P) 类型或大小的独立预测值尚未得到充分确立.
研究的目的:
- 调查apoB粒子类型或大小是否为事件CAD增加了预测价值.
- 为了确定apoB-P和脂蛋白的联合预后值,用于CAD风险评估.
主要方法:
- 对207,368名没有先前心血管疾病或糖尿病的英国生物库参与者的前性分析.
- 考克斯回归模型评估了各种脂质参数 (apoB-P,VLDL,LDL,颗粒大小,Lp(a)) 和发生的CAD之间的关联.
主要成果:
- 在apoB-P中增加1SD与33%更高的CAD风险有关.
- 虽然VLDL颗粒的每颗粒风险高于LDL,但考虑到颗粒数量,它们对整体风险的贡献是相似的.
- 颗粒大小没有独立于apoB-P预测CAD; Lp(a) 提供了额外的独立预测值.
结论:
- 总的apoB-P计数是最准确地反映了与脂质相关的动脉样硬化风险,不受主要颗粒类型或大小的影响.
- 升高的Lp(a) 水平独立地增加了CAD风险.
- 为了最佳地评估与失脂血症相关的动脉质风险,需要考虑apoB-P和Lp (a) 度.

Lipid-derived Compounds in the Human Body
4.2K
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...

Cholesterol: Significance and Regulation
457
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.

Ischemic Heart Disease: Overview

Ischemic heart disease occurs when the heart's blood supply dwindles, causing an ominous lack of oxygen and nutrients. This deficiency, stemming from reduced or obstructed blood flow, spells danger, leading to heart muscle damage and dysfunction.
Atherosclerosis, the primary malefactor, orchestrates this dangerous condition. It manifests as the accumulation of fatty deposits, akin to insidious plaques, within arterial walls. As time elapses, these plaques metamorphose, hardening and...
