how are ldl and hdl associated with the risk for heart disease?

High levels of LDL cholesterol lead to atherosclerosis increasing the risk of heart attack and ischemic stroke. HDL cholesterol reduces the risk of cardiovascular disease as it carries cholesterol away from the blood stream.

Saturated fats raise high-density lipoprotein (HDL or "good") cholesterol and low-density lipoprotein (LDL or "bad") cholesterol levels, which may increase your risk of cardiovascular disease. Trans fat. This type of fat occurs naturally in some foods in small amounts.

HDL participates in reverse cholesterol transport, which is the transport of cholesterol back to the liver. HDL picks up cholesterol from tissues/blood vessels and returns it to the liver itself or transfers it to other lipoproteins returning to the liver.

Diabetes and high cholesterol often occur together The American Heart Association (AHA) states that diabetes often lowers HDL (good) cholesterol levels and raises triglycerides and LDL (bad) cholesterol levels. Both of these increase the risk for heart disease and stroke.

High cholesterol is associated with an elevated risk of cardiovascular disease. That can include coronary heart disease, stroke, and peripheral vascular disease. High cholesterol has also been linked to diabetes and high blood pressure.

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.

Doctors calculate an individual's cholesterol ratio by dividing their total cholesterol by their high-density lipoprotein level. The optimal ratio is between 3.5 and 1. A higher ratio increases the risk of 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.
747775
An excess amount of blood lipids can cause fat deposits in your artery walls, increasing your risk for heart disease.
1468602
HDL takes the "bad," LDL (low density lipoprotein) cholesterol out of your blood and keeps it from building up in your arteries. LDL cholesterol is known as bad cholesterol because it leads to the development and build up of plaque on the walls of your arteries.
1056380
LDL is the main source of artery-clogging plaque. HDL actually works to clear cholesterol from the blood. Triglycerides are another fat in our bloodstream. Research is now showing that high levels of triglycerides may also be linked to heart disease.

LDL and HDL have different purposes: LDL stands for low-density lipoproteins. It is sometimes called the "bad" cholesterol because a high LDL level leads to a buildup of cholesterol in your arteries. HDL stands for high-density lipoproteins.

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.

HDL cholesterol is the well-behaved "good cholesterol." This friendly scavenger cruises the bloodstream. As it does, it removes harmful bad cholesterol from where it doesn't belong. High HDL levels reduce the risk for heart disease -- but low levels increase the risk.

People with normal HDL cholesterol can have heart disease. And people with low HDL levels can have healthy hearts. Overall, though, people who have low HDL cholesterol will have greater risk of developing heart disease than people with high HDL levels.
