Is high blood cholesterol a risk factor for coronary heart disease?

The main risk associated with high cholesterol is coronary heart disease (CHD). Your blood cholesterol level has a lot to do with your chances of getting heart disease. If your cholesterol is too high, it builds up on the walls of your arteries. Over time, this buildup is known as atherosclerosis.

What is the risk of having high LDL?

Risks of High LDL Cholesterol Coronary artery disease. Peripheral artery disease. Heart disease, including chest pain (angina) and heart attack. Stroke.

Is high LDL a risk factor for atherosclerosis?

Atherosclerosis is a multifactorial disease. The impact of traditional risk factors such as age, sex, elevated blood pressure, smoking, high levels of LDL cholesterol, and low levels of HDL cholesterol on CHD risk has long been demonstrated beyond any doubt.

What does a high HDL cholesterol level mean?

For HDL cholesterol, or “good” cholesterol, higher levels are better. 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.

Does lowering LDL prevent heart disease?

It also occurs in arteries elsewhere in your body, causing problems such as stroke, kidney failure and poor circulation.). In addition, studies show that lowering LDL cholesterol reduces risk for coronary heart disease.

What does cholesterol risk factor mean?

Certain health conditions, your lifestyle, and your family history can raise your risk for high cholesterol. These are called “risk factors.” You can’t control some of these risk factors, such as your age or your family history.

What is the functional difference between LDL and HDL?

HDL helps rid your body of excess cholesterol so it’s less likely to end up in your arteries. LDL is called “bad cholesterol” because it takes cholesterol to your arteries, where it may collect in artery walls. Too much cholesterol in your arteries may lead to a buildup of plaque known as atherosclerosis.

Why does LDL cause atherosclerosis?

In the early stages of atherosclerosis, LDL that has entered the artery wall attracts and is engulfed by important immune system cells called macrophages that ingest, or “eat,” LDL particles. LDL-laden macrophages become foam cells that promote inflammation and further the development of atherosclerotic plaques.

How does HDL and LDL levels reflect the risk and progression of atherosclerosis?

T cells enhance activation of macrophages. HDL helps prevent atherosclerosis. It has long been recognized that the cholesterol concentrations in the blood are indicators of the probability that a plaque will develop: higher LDL and lower HDL concentrations indicate a higher probability of plaque development.
