Insights

Lowering low-density lipoprotein cholesterol (LDLc) improves survival in vascular disease patients. However, atherogenic lipoprotein phenotype (ALP) also contributes to atherosclerotic vascular disease (AVD) through complex mechanisms.

Area of Science:

  • Cardiovascular Medicine
  • Lipid Metabolism
  • Atherosclerosis Research

Background:

  • Reducing low-density lipoprotein cholesterol (LDLc) improves survival by 20-30% in patients with pre-existing vascular disease.
  • Established atherosclerotic vascular disease (AVD) is largely irreversible with current therapies.
  • Other factors beyond LDLc contribute to AVD, including the atherogenic lipoprotein phenotype (ALP).

Purpose of the Study:

  • To review the mechanisms linking the atherogenic lipoprotein phenotype (ALP) to atherosclerotic vascular disease (AVD).
  • To explore how triglyceride-rich lipoproteins contribute to AVD.
  • To discuss the role of ALP in platelet function, coagulation, and vascular inflammation.

Main Methods:

  • Review of existing angiographic studies.
  • Analysis of recent evidence on procoagulant and proinflammatory states.
  • Discussion of proposed mechanisms linking ALP to AVD.

Main Results:

  • Established atherosclerotic vascular disease (AVD) is often irreversible.
  • The atherogenic lipoprotein phenotype (ALP), characterized by lipoprotein abnormalities, is a significant risk factor for AVD.
  • The precise mechanisms linking ALP to AVD are not fully understood but may involve procoagulant and proinflammatory pathways.

Conclusions:

  • Current LDLc-lowering therapies have limitations in fully reversing established atherosclerotic vascular disease (AVD).
  • The atherogenic lipoprotein phenotype (ALP) plays a crucial role in AVD development.
  • Further research is needed to elucidate how ALP, particularly triglyceride-rich lipoproteins, impacts vascular health via platelet function, coagulation, and inflammation.

Atherosclerosis I: Introduction

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...

Blood Studies for Cardiovascular System III: Serum Lipid Profile

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...

Coronary Artery Disease II: Pathophysiology

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...

Lipid-derived Compounds in the Human Body

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, delayed...

Cholesterol: Significance and Regulation

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.
Considering cholesterol and...
