What role does HDL play in preventing coronary heart disease?

What role does HDL play in preventing coronary heart disease?

HDL (high-density lipoprotein), or “good” cholesterol, absorbs cholesterol and carries it back to the liver. The liver then flushes it from the body. High levels of HDL cholesterol can lower your risk for heart disease and stroke.

How HDL good cholesterol can be helpful in minimizing risk for heart disease?

Experts believe HDL cholesterol may act in a variety of helpful ways that tend to reduce the risk for heart disease: HDL cholesterol scavenges and removes LDL — or “bad” — cholesterol. HDL reduces, reuses, and recycles LDL cholesterol by transporting it to the liver where it can be reprocessed.

What is the relationship between HDL cholesterol and risk of coronary artery disease?

Epidemiological studies clearly show that levels of high-density lipoprotein cholesterol (HDL-C) are inversely associated with the risk of coronary artery disease and its thrombotic complications.

What does protective HDL mean?

This helps to prevent excess accumulation, which is why it is also referred to as “good cholesterol.” High levels of HDL cholesterol have always been considered to be protective for heart health .

How important is HDL cholesterol?

HDL cholesterol helps rid the body of bad cholesterol and keeps it from collecting on the linings of your arteries. Cholesterol buildup can lead to severe health events such as heart attack or stroke. Having lower HDL cholesterol does not appear to cause problems directly.

How does HDL help with atherosclerosis?

High-density lipoproteins (HDLs) oppose atherosclerosis directly, by removing cholesterol from foam cells, by inhibiting the oxidation of LDLs, and by limiting the inflammatory processes that underlie atherosclerosis.

What is HDL cholesterol good for?

High-density lipoprotein (HDL) cholesterol is known as the “good” cholesterol because it helps remove other forms of cholesterol from your bloodstream. Higher levels of HDL cholesterol are associated with a lower risk of heart disease.

What is the relationship between the level of HDL cholesterol and the risk of developing atherosclerosis?

Levels of high-density lipoprotein (HDL) cholesterol are generally inversely associated with the risk for the development of atherosclerosis. The mechanism by which HDL imparts protection from the initiation and progression of occlusive vascular disease is complex and multifactorial.

Is HDL really protective?

Because the HDL molecule is involved in helping cholesterol move away from blood and blood-vessel walls, high levels have been considered protective against clogged arteries and atherosclerosis.
