Too much LDL (bad) cholesterol can combine with other substances in your blood to contribute to plaque buildup in your arteries, a condition called atherosclerosis, which over many years can lead to coronary heart disease. This brochure lists the conditions that may put you at risk for coronary heart disease and the goals for treating the disease.

Cholesterol, Coronary Heart Disease, and Atherosclerosis
Coronary heart disease (CHD) is a disease in which a waxy substance called plaque builds up inside the coronary arteries. These arteries supply oxygen-rich blood to your heart muscle.
Too much LDL (bad) cholesterol can combine with other substances in the blood to contribute to plaque buildup.
When plaque builds up in the arteries, the condition is called atherosclerosis. The buildup of plaque occurs over many years.

If the flow of oxygen-rich blood to your heart muscle is reduced or blocked, angina or a heart attack can occur.
Angina is chest pain or discomfort. It may feel like pressure or squeezing in your chest. The pain can also occur in your shoulders, arms, neck, jaw, or back. Angina pain may even feel like indigestion.
A heart attack occurs if the flow of oxygen-rich blood to a section of heart muscle is cut off. If blood flow isn?t restored quickly, the section of heart muscle begins to die. Without quick treatment, a heart attack can lead to serious health problems or death.
