Definition
You have this condition if there are high levels of cholesterol in the blood. There are three parts of cholesterol:
- Low density lipoproteins (LDL)—known as bad cholesterol. It causes build up of cholesterol and other fats in the blood vessels. High LDL levels can cause artery and heart disease.
- High density lipoproteins (HDL)—known as good cholesterol. It can remove cholesterol and other fats from the blood vessels. High levels of HDL can protect against heart disease.
- Triglycerides—a common form of fat in the body. Often elevated in people with diabetes or certain genetic conditions.
- Particles—proteins associated with certain types of cholesterols in the body. These may be a better signal about your risk of developing disease in the blood vessels.

Statins
are often prescribed for high cholesterol. They have been shown to reduce mortality (death),
heart attacks, and stroke. Ezetimibe has reduced plaque in arteries. However, it has not been shown to reduce mortality.
