Summary
Lowering cholesterol can reduce coronary heart disease (CHD) risk, but interventions may increase risks for cancer, stroke, and death. Careful consideration of benefits versus harms is crucial for patients with hypercholesterolemia.
Area of Science:
- Cardiovascular Medicine
- Pharmacology
Background:
- Hypercholesterolemia is a significant risk factor for coronary heart disease (CHD).
- Cholesterol reduction is a primary target for preventing cardiovascular events.
Purpose of the Study:
- To review the controversies surrounding cholesterol-lowering interventions for coronary heart disease (CHD) prevention.
- To evaluate the risks and benefits associated with reducing serum cholesterol concentrations.
Main Methods:
- Literature search of MEDLINE (1966-1995) and bibliographies.
- Inclusion of studies, reviews, and editorials on cholesterol-lowering controversies.
- Synthesis of pertinent information into a review format.
Main Results:
- Cholesterol lowering effectively reduces CHD incidence.
- However, certain cholesterol-lowering medications may elevate risks for cancer, stroke, and mortality.
- The benefits of cholesterol reduction may not universally outweigh potential risks.
Conclusions:
- Cholesterol-lowering interventions can significantly reduce serum cholesterol.
- Risk-benefit assessment is critical, especially for patients with increased risk of cancer, stroke, or depression.
- Caution is advised with fibric acid derivatives in patients with existing CHD.

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,...

01:22Cholinesterases: Distribution and Function
1.3K
Cholinesterases are a group of serine hydrolase enzymes that play a crucial role in the breakdown of choline esters. The two primary types of cholinesterases are acetylcholinesterases (AChEs) and butyrylcholinesterase (BuChEs), which differ in their distribution, function, and substrate specificity. AChEs, also known as true cholinesterases, specifically hydrolyze acetylcholine, while BuChEs, often referred to as pseudocholinesterases, can hydrolyze various choline esters, including...

3.1K
Cholinergic antagonists bind to cholinergic receptors and limit the effects of acetylcholine and other cholinergic agonists. Based on the specific cholinergic receptor affinity, these antagonists are classified as muscarinic or nicotinic. Anticholinergics interrupt parasympathetic innervations while sympathetic innervations remain uninterrupted. Muscarinic antagonists are also called 'muscarinic antagonists', 'antimuscarinics', or 'parasympatholytics'. Nicotinic...

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...

2.4K
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...

01:29Cholesterol: Significance and Regulation
1.9K
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.
