Your blood cholesterol level has a lot to do with your chances of getting heart disease. High blood cholesterol is one of the major risk factors for heart disease. A risk factor is a condition that increases your chance of getting a disease. In fact, the higher your blood cholesterol level, the greater your risk for developing heart disease or having a heart attack. Heart disease is the number one killer of women and men in the United States. Each year, more than a million Americans have heart attacks, and about a half million people die from heart disease.
When there is too much cholesterol (a fat-like substance) in your blood, it builds up in the walls of your arteries. Over time, this buildup causes “hardening of the arteries” so that arteries become narrowed and blood flow to the heart is slowed down or blocked. The blood carries oxygen to the heart, and if enough blood and oxygen cannot reach your heart, you may suffer chest pain. If the blood supply to a portion of the heart is completely cut off by a blockage, the result is a heart attack.
High blood cholesterol itself does not cause symptoms, so many people are unaware that their cholesterol level is too high. It is important to find out what your cholesterol numbers are because lowering cholesterol levels that are too high lessens the risk for developing heart disease and reduces the chance of a heart attack or dying of heart disease, even if you already have it. Cholesterol lowering is important for everyone–younger, middle age, and older adults; women and men; and people with or without heart disease.
If it is not possible to get a lipoprotein profile done, knowing your total cholesterol and HDL cholesterol can give you a general idea about your cholesterol levels. If your total cholesterol is 200 mg/dL or more or if your HDL is less than 40 mg/dL*, you will need to have a lipoprotein profile done.
See how your cholesterol numbers compare to the tables below.
|Total Cholesterol Level||Category|
|Less than 200 mg/dL||Desirable|
|200-239 mg/dL||Borderline High|
|240 mg/dL and above||High|
* Cholesterol levels are measured in milligrams (mg) of cholesterol per deciliter (dL) of blood.
|LDL Cholesterol Level||LDL-Cholesterol Category|
|Less than 100 mg/dL||Optimal|
|100-129 mg/dL||Near optimal/above optimal|
|130-159 mg/dL||Borderline high|
|190 mg/dL and above||Very high|
HDL (good) cholesterol protects against heart disease, so for HDL, higher numbers are better. A level less than 40 mg/dL is low and is considered a major risk factor because it increases your risk for developing heart disease. HDL levels of 60 mg/dL or more help to lower your risk for heart disease.
