概括
在冠状动脉CT血管学中,高周周血管脂肪衰减指数 (FAI) 表明非化斑块. 低FAI与化斑块有关,表明不同的冠状动脉疾病表型.
科学领域:
- 心血管成像 - 心血管成像
- 无线电学 (Radiomics) 是一种辐射学.
- 生物标志物发现发现
背景情况:
- 冠状动脉CT血管学 (CCTA) 的周周血管脂肪衰减指数 (FAI) 量化了血管炎症.
- 作为冠状动脉疾病 (CAD) 风险分层的生物标志物,FAI显示出希望.
研究的目的:
- 为了评估冠状动脉动脉硬性斑块的特征,基于高或低的冠状动脉脂肪组织FAI.
- 在CAD患者中比较高和低FAI表型之间的斑块特征.
主要方法:
- 针对疑似或确定的CAD接受CCTA的患者的回顾性分析.
- 冠状动脉病变分为高 (≥-70.1 HU) 或低FAI (<-70.1 HU) 现型.
- 在FAI组之间比较患者和病变特征.
主要成果:
- 36个病变 (14.6%) 显示高FAI,211个 (85.4%) 显示低FAI.
- 高FAI病变的非化斑块体积 (NCPV) 显著增加 (111.8 mm3对比87.7 mm3).
- 据NCPV预测,脂肪衰减呈阳性斑块;高FAI病变较少出现均质化 (25%与46.9%相比).
结论:
- 具有高FAI表型的冠状动脉病变主要具有非化斑块.
- 低FAI表型病变主要是化的,看起来更均.
- 需要进一步的前性研究来验证发现并探索机制.

Coronary Artery Disease II: Pathophysiology
815
Coronary Artery Disease (CAD) originates from a series of events that impair the function of coronary arteries, the blood vessels responsible for delivering oxygen-rich blood to the heart muscle. The pathophysiology of CAD is closely linked to atherosclerosis, a chronic inflammatory and lipid-driven condition affecting the vascular endothelium.1. Endothelial DamageThe process begins with damage to the vascular endothelium, which serves as a protective barrier between the blood and the vessel...

Atherosclerosis I: Introduction
1.6K
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...

Peripheral Artery Disease I: Introduction
487
Peripheral artery disease (PAD) predominantly results from atherosclerosis, which involves the accumulation of fatty deposits, or plaques, within the walls of arteries. This causes them to narrow and harden, significantly reducing blood flow. PAD predominantly affects the legs, particularly the arteries supplying the thighs and calves. In rare cases, it may involve other arteries, including those in the arms.Etiology of PAD:The principal cause of PAD is atherosclerosis, which results from fatty...

Coronary Artery Disease (CAD): An Overview with Scientific InsightsCoronary Artery Disease (CAD), often referred to as C-A-D, is a prevalent blood vessel disorder classified under the broader category of atherosclerosis. Atherosclerosis is a pathological process characterized by the hardening and narrowing of arteries due to the accumulation of atherosclerotic plaques. These plaques are composed of cholesterol, fatty substances, inflammatory cells, calcium, and fibrin, reducing blood flow to...

Lipid-derived Compounds in the Human Body
7.2K
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,...
