Why is LDL more atherogenic?
We hypothesize that small dense LDL might be more atherogenic than normal size LDL due to decreased hepatic clearance by the LDL receptor, and enhanced anchoring to LDL receptor-independent binding sites in extrahepatic tissues (e.g., the arterial wall), a process mediated, in part, by cell surface proteoglycans.
Is LDL atherogenic?
Despite overwhelming evidence that LDL is an atherogenic lipoprotein, the precise mechanisms whereby LDL promotes atherosclerosis remain unknown. According to current concepts, circulating LDL particles filter into the arterial wall, where they elicit an atherogenic response.
Is LDL more atherogenic than HDL?
Low-density lipoprotein (LDL) is the major source of atherosclerotic lipid storage, whereas high-density lipoprotein (HDL) is not atherogenic, and its level inversely correlates with the atherosclerotic CVD risk [8].
What is LDL in atherosclerosis?
Atherosclerosis is a disease in which a plaque builds up inside the arteries. A plaque contains low density lipoprotein (LDL), macrophages, smooth muscle cells (SMCs), platelets, and debris. The plaque constricts the lumen of the blood vessel thereby increasing the shear force of blood flow [3], [4].
Which lipoprotein is most atherogenic?
small dense LDL
Our data indicate that small dense LDL is the most atherogenic lipoprotein parameter.
What is an atherogenic?
Atherogenic index of plasma (AIP) is a novel index composed of triglycerides and high-density lipoprotein cholesterol [6]. It has been used to quantify blood lipid levels and commonly used as optimal indicator of dyslipidemia and associated diseases (e.g., cardiovascular diseases) [7,8,9].
Which type of lipoproteins are atherogenic?
LDL is considered an atherogenic part of the lipoprotein system (Kwiterovich 2002a, 2002b). LDL transports a major cholesterol load from the liver to the peripheral cells of the body.
Does low LDL cause atherosclerosis?
Low-density lipoproteins cause atherosclerotic cardiovascular disease. 1. Evidence from genetic, epidemiologic, and clinical studies.
What are atherogenic lipoproteins?
Atherogenic lipoprotein particle concentrations were associated with cardiovascular disease risk when LDL cholesterol was low. VLDL lipoproteins, particularly the smallest remnant subclass, may represent unused targets for risk prediction and potential therapeutic intervention for reducing residual risk.
What are atherogenic lipids?
Abstract. Atherogenic lipids, particularly oxidized low-density lipoprotein, are responsible for a wide range of cellular dysfunctions within the vessel wall.
What is atherogenic lipid profile?
Atherogenic dyslipidemia (AD) is a blood serum lipid profile abnormality characterized by elevation of triglycerides and reduced levels of high density lipoprotein cholesterol (HDL-C). It is associated with residual cardiovascular risk.
What is atherogenic index in cholesterol?
The atherogenic index of plasma (AIP) is calculated as log (TG/HDL) and reflects the levels of TG and HDL-C cholesterol. AIP, as a robust biomarker of dyslipidemia and AS, has been used to quantify comprehensive lipid levels (9). It is also considered a biomarker of coronary syndrome and metabolic syndrome (10, 11).
