What Is Your Risk of Developing Heart Disease or Having a Heart Attack?

In general, the higher your LDL level and the more risk factors you have (other than LDL), the greater your chances of developing heart disease or having a heart attack. Some people are at high risk for a heart attack because they already have heart disease. Other people are at high risk for developing heart disease because they have diabetes (which is a strong risk factor) or a combination of risk factors for heart disease. Follow these steps to find out your risk for developing heart disease.

Step 1: Check the table below to see how many of the listed risk factors you have; these are the risk factors that affect your LDL goal.

Cholesterol levels: What numbers should you aim for?

Figuring out the best cholesterol levels to aim for can be confusing. But here's some help setting your cholesterol number targets.

By Mayo Clinic staff

It's important to keep your cholesterol levels within healthy limits. And if you have other risk factors for developing heart disease, you need to be even more careful — especially with your low-density lipoprotein (LDL), or "bad," cholesterol level.

Interpreting your cholesterol numbers

Cholesterol levels are measured in milligrams (mg) of cholesterol per deciliter (dL) of blood in the United States and some other countries. Canada and most European countries measure cholesterol in millimoles (mmol) per liter (L) of blood. Consider these general guidelines when you get your cholesterol test (lipid panel or lipid profile) results back to see if your cholesterol falls in an ideal range.

High Cholesterol Risks: Top 2 Dangers

A lot of people don't take the risks of high cholesterol very seriously. After all, one out of six people have high cholesterol. A staggering 50% of Americans have levels above the suggested limit. Could something so common really be a serious health risk?

Unfortunately, yes. Cholesterol is a direct contributor to cardiovascular disease, which can lead to strokes and heart attacks.

"Despite all of the amazing medicines and treatments we have, cardiovascular disease is still the number one cause of death and illness in our society," says Laurence S. Sperling, MD, director of preventive cardiology at the Emory University School of Medicine, Atlanta, Ga.

The World Health Organization estimates that almost 20% of all strokes and over 50% of all heart attacks can be linked to high cholesterol. 

But if you've been diagnosed with high cholesterol, don't despair. The good news is that high cholesterol is one risk factor for strokes and heart attacks that you can change. You just need to take action now, before your high cholesterol results in more serious disease.

Wikipedi For Cholesterol

Cholesterol

Cholesterol is a waxy steroid of fat that is produced in the liver or intestines. It is used to produce hormones and cell membranes and is transported in the blood plasma of all mammals.^[2] It is an essential structural component of mammalian cell membranes and is required to establish proper membrane permeability and fluidity. In addition, cholesterol is an important component for the manufacture of bile acids, steroid hormones, and vitamin D. Cholesterol is the principal sterol synthesized by animals; however, small quantities can be synthesized in other eukaryotes such as plants and fungi. It is almost completely absent among prokaryotes including bacteria.^[3] Although cholesterol is important and necessary for mammals, high levels of cholesterol in the blood have been linked to damage to arteries and are potentially linked to diseases such as those associated with the cardiovascular system (heart disease).^[4]

The name cholesterol originates from the Greek chole- (bile) and stereos (solid), and the chemical suffix -ol for an alcohol. François Poulletier de la Salle first identified cholesterol in solid form in gallstones, in 1769. However, it was only in 1815 that chemist Eugène Chevreul named the compound "cholesterine".^[5]

What is high cholesterol?

Cholesterol is a type of fat (lipid) in your blood. Your cells need cholesterol, and your body makes all it needs. But you also get cholesterol from the food you eat.

If you have too much cholesterol, it starts to build up in your arteries . (Arteries are the blood vessels that carry blood away from the heart.) This is called hardening of the arteries, or atherosclerosis . It is usually a slow process that gets worse as you get older.

To understand what happens, think about how a clog forms in the pipe under a kitchen sink. Like the buildup of grease in the pipe, the buildup of cholesterol narrows your arteries and makes it harder for blood to flow through them. It reduces the amount of blood that gets to your body tissues, including your heart. This can lead to serious problems, includingheart attack and stroke.
