LDL中的胆固醇容易在血管壁沉积形成斑块导致动脉硬化,HDL中的胆固醇帮助清除血管壁多余胆固醇并运回肝脏代谢。 1. LDL功能分析:LDL负责将胆固醇从肝脏运输到外周组织。当血液中LDL浓度过高时,多余的胆固醇会被氧化并渗入血管内皮,引发泡沫细胞形成和动脉粥样硬化斑块。2. HDL的逆向运输机制:HDL可将外周组织
HDL 携带的胆固醇主要是使之回到肝脏中去,从而得以得到代谢并排除,最后可以达到一个减少胆固醇沉积的作用,提供动脉血管的HDL,血浆胆固醇量其实是减少的。 所以说低密度脂蛋白(LDL)中的胆固醇是“bad cholesterol” ,而高密度脂蛋白(HDL)中的胆固醇是“good cholesterol”。反馈...
A large observational study suggests that high levels of ‘good’ (HDL) cholesterol may increase the risk of glaucoma, while higher levels of ‘bad’ (LDL) cholesterol may be protective—particularly in individuals over 55. ‘Good’ cholesterol may be linked to an increased risk of glaucoma in...
The study, presented at this year's American Heart Association meeting and published in this week's Journal of the American Medical Association, found that evacetrapib, either alone or in combination with cholesterol-loweringstatins, increased HDL cholesterol and lowered LDL cholesterol. "The drug...
What Is HDL Cholesterol? Total cholesterol is a measure of the total amount of cholesterol in your blood, which includes HDL, LDL andtriglycerides. However, total cholesterol is mainly made up of LDL or “bad” cholesterol. Having high levels of low-density lipoprotein or LDL can lead to pla...
One such type of drug is called a CETP inhibitor, intended to reduce "bad" cholesterol (LDL) and raise "good" cholesterol (HDL). 胆固醇酯转运蛋白抑制剂就是一种这一类型的药,它可以减少“坏”的胆固醇(低密度脂蛋白),同时增加“好”的胆固醇(高密度脂蛋白)。 article.yeeyan.org 3. HDL (good ...
for approximately 9 hours before the exam to ensure correct evaluation results., whilerecent studiessuggest that it is not necessary. With this guide, you will understand what your results mean. You will know about the total cholesterol, the HDL, the LDL, the triglycerides and even a less pop...
LDL cholesterol contributes to plaque build-up in the arteries, which can eventually lead to heart disease, heart attack or stroke, according to theAmerican Heart Association. On the other hand, HDL cholesterol helps heart health by carrying some LDL cholesterol away from the arteries and back to...
“The elevation in dementia risk with both high and low levels of HDL cholesterol was unexpected, but these increases are small, and their clinical significance is uncertain,” Glymour said. “In contrast, we found no association between LDL cholesterol and dementia risk in the overall study coho...
(LDL) cholesterol and triglycerides in heart disease. While conventional lab tests measure overall blood levels of HDL, a new study suggests that a novel lab test that analyzes specific HDL proteins may better predict risk of -- and death by -- coronary he...
