Insights

This review highlights lipid risks for atherosclerotic cardiovascular disease (ASCVD) beyond LDL cholesterol. Emerging evidence supports targeting remnant particles and lipoprotein(a) for better ASCVD prevention, especially with rising obesity rates.

Area of Science:

  • Cardiology
  • Metabolic Syndrome
  • Lipidology

Background:

  • High LDL cholesterol is a primary driver of atherosclerotic cardiovascular disease (ASCVD).
  • Decades of research focused on lowering LDL cholesterol levels.
  • Increasing global rates of obesity, insulin resistance, diabetes, and metabolic syndrome necessitate broader risk assessment.

Purpose of the Study:

  • To provide an overview of lipid-related ASCVD risks beyond LDL cholesterol.
  • To discuss the role of remnant particles and lipoprotein(a) in ASCVD.
  • To emphasize the growing importance of targeting metabolic dysregulation and genetic lipid drivers of ASCVD.

Main Methods:

  • Review of interventional, mechanistic, observational, and genetic studies.
  • Analysis of evidence supporting causal roles of remnant particles and lipoprotein(a).
  • Discussion of emerging therapeutic strategies targeting these lipoproteins.

Main Results:

  • Elevated remnant particles and high lipoprotein(a) are causally linked to ASCVD development.
  • Lipoprotein(a) levels are genetically determined.
  • Remnant cholesterol levels strongly correlate with overeating, obesity, and diabetes.

Conclusions:

  • Focus is shifting beyond LDL cholesterol to additional ASCVD risk measures.
  • New drugs targeting remnant particles and lipoprotein(a) are under development.
  • Targeting lipids involved in metabolic dysregulation and genetic drivers is crucial for future ASCVD prevention, particularly in the context of the obesity pandemic.

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...

Lipid-Lowering Drugs: Statins and Miscellaneous Agents

Hyperlipidemia, a medical condition often referred to as high cholesterol, is characterized by abnormally elevated levels of lipids in the bloodstream. When present in excess, these lipids, specifically cholesterol and triglycerides, can lead to serious health complications, often involving cardiovascular diseases. Illnesses like atherosclerosis, heart attacks, and pancreatitis have all been linked to untreated hyperlipidemia. This means controlling and regulating cholesterol and triglyceride...

Lipids: Dietary Sources and Requirements

Lipids are an essential component of a balanced human diet. Triglycerides, which make up the majority of dietary lipids, are found in both saturated fats—commonly present in meat, dairy products, and certain tropical plants like coconut, and hydrogenated oils such as margarine and baking shortenings (trans fats)—and unsaturated fats, which are abundant in seeds, nuts, olive oil, and most vegetable oils. The main sources of cholesterol include egg yolks, various meats and organ meats, shellfish,...

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...

Overview of Lipid Metabolism

Lipid metabolism is a crucial process in the human body that involves the synthesis and degradation of lipids. This process is essential for energy production, cell membrane formation, and hormone production, among other functions.
Lipolysis: The Breakdown of Lipids:
Lipolysis is the process of breaking down lipids, particularly triglycerides, into glycerol and fatty acids. This process typically occurs in the adipose tissue and is triggered by various hormones, including glucagon and...

Atherosclerosis III: Management

Management of atherosclerosis involves an integrated strategy encompassing pharmacological treatment, surgical interventions, lifestyle changes, and nutrition therapy to address the multifactorial nature of the disease.Pharmacological TherapyA cornerstone of atherosclerosis management is the use of pharmacological agents. Statins, such as atorvastatin, are pivotal in inhibiting HMG-CoA reductase, an enzyme that catalyzes an initial step in cholesterol synthesis in the liver. This reduction in...
