The U.S. National Cholesterol Education Program's (NCEP's)
recommendations for treatment with medicine are based on cholesterol levels and
the number of risk factors you have for heart attack.1, 2 The guidelines provide a good
starting point for treatment. Individual risk assessment is important to
determine whether starting medicine to lower your cholesterol is appropriate
for you.
If you have any risk for heart disease, therapeutic lifestyle changes
(losing weight, exercising, and eating a diet that is low in saturated fat) are
recommended, whether or not you are taking medicine.
Risk factors for heart disease include:
- Smoking cigarettes.
- Having high blood
pressure or taking blood pressure
medicine.
- Diabetes.
- Low HDL cholesterol (below 40
mg/dL).
- Having a first-degree male relative, such as a father or
brother, who had heart disease before he was 55 years old; or having a
first-degree female relative, such as a mother or sister, who had heart disease
before she was 65 years old.
- Age. People over 65 are more likely to
have coronary artery disease (CAD).

Attack?
Lower risk
People who are at low risk do not have
coronary artery disease (CAD) and have one or no risk
factors for heart disease. Consider starting medicine when:
- LDL is 190 mg/dL or higher. The goal of
medication is to lower LDL below 160 mg/dL.
When LDL cholesterol is between 160 mg/dL and 189 mg/dL, beginning
medicine is optional. The goal is still to lower LDL cholesterol to below 160
mg/dL.
Moderate risk
People who are at moderate risk for CAD have 2 or more risk factors
and have less than a 10% risk of having a heart attack in 10 years.
Consider starting medicine when:
- LDL is 160 mg/dL or higher. The goal of
treatment with medicine is to lower LDL below 130 mg/dL.
Moderately high risk
People who are at moderately high risk for CAD have 2 or more risk
factors and a 10% to 20% risk of having a heart attack in 10 years.
Consider starting medicine when:
- LDL is 130 mg/dL or higher. The goal of
treatment with medicine is less than 130 mg/dL.
- LDL is 100 to 129
mg/dL. If your goal is less than 100 mg/dL, then medicine is an option.
High risk
People who are at high risk for CAD have more than a 20% chance of
having a heart attack in 10 years and have CAD, have had a
heart attack, have
stable or
unstable angina, or have had
angioplasty or
bypass surgery. This category also includes people who
have diseases or conditions that are considered equally as serious as CAD, such
as
peripheral arterial disease, abdominal
aortic aneurysm,
transient ischemic stroke or
ischemic stroke, and
diabetes.
Consider starting medicine when:
- LDL is 100 mg/dL or more. Treatment goal is
less than 100 mg/dL, with an option to use medicines to lower LDL to 70 mg/dL,
especially for people who are at very high risk (who
have CAD and diabetes,
acute coronary syndrome, or
metabolic syndrome or who smoke
cigarettes).
- LDL is less than 100 mg/dL but HDL is below 40 mg/dL
or
triglycerides are high. Your doctor may consider
adding additional medicines (fibrate or nicotinic acid) to a
statin.
Additional recommendations
If you have a moderately high or high risk of heart attack and you
are obese or physically inactive, or you have high triglycerides, low HDL, or
metabolic syndrome, you should begin therapeutic lifestyle changes even if your
LDL is below 100 mg/dL.
If you have a moderately high or high risk of heart attack, and
your doctor has advised you to take medicines, the guidelines recommend that
the treatment be intense enough to lower your LDL 30% to 40%.
