- 冠状动脉化 (CAC) 是一种广泛使用的成像生物标志物,用于预测心血管疾病事件.
- sd-LDL-C和CAC之间的关系尚未得到广泛的研究.
研究的目的:
- 调查直接测量的sd-LDL-C与CAC的存在之间的关联.
- 为了确定sd-LDL-C是否提供了超越传统LDL-C测量的CAC的额外预测价值.
主要方法:
- 从多民族动脉样硬化研究中分析了4672名个人,使用了基线sd-LDL-C和CAC数据.
- 利用多变量通用线性模型和受限立方线来评估关联.
- 调整以人口统计,心血管风险因素和估计的总LDL-C.
主要成果:
- sd-LDL-C 的较高四分位数与 CAC 的存在有显著的关联.

164
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...

01:29Cholesterol: 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.

01:20Imaging Studies for Cardiovascular System III: X-Ray
188
The most common cardiovascular diagnostic test is an X-ray. It produces images of the heart, blood vessels, and adjacent structures.
Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
