The National Cholesterol Education Program (NCEP) offers cholesterol guidelines for men and women.
High levels of LDL cholesterol and/or low levels of high-density lipoprotein (HDL, or “good”) cholesterol, are major risk factors for heart attack and stroke, two of the most common causes of death in the US.
Screening for lipid disorders like high cholesterol depends on your age and whether you have any risk factors for heart disease. In general, if you are a healthy adult aged 20 or older, your doctor may recommend that you have a screening test every five years. The test results for total cholesterol are:
If your total cholesterol level is over 240 mg/dL (6.2 mmol/L), you have a higher risk of heart disease compared to someone whose cholesterol is below 200 mg/dL (5.2 mmol/L).
The guidelines propose different recommendations depending on a person’s degree of risk of heart attack within the next ten years. This risk is determined by the presence of several risk factors, including history of heart attack or stroke, unstable or stable angina (chest pain), history of coronary artery procedures, evidence of clogged arteries (myocardial ischemia), diabetes, metabolic syndrome, high LDL cholesterol, low HDL cholesterol, high blood pressure, smoking, family history of heart disease, and age.
There are three major risk levels:
NCEP's recommendations include:
|Risk Category||Drug Therapy Based on LDL levels|
|Moderately high risk|
The guidelines also state that drug treatment for high-risk patients must be aggressive enough to achieve at least a 30%-40% reduction in LDL levels. In addition to drug therapy, NCEP stresses the importance of initiating therapeutic lifestyle changes in high-risk persons—regardless of cholesterol level—since lifestyle changes can reduce cardiovascular risk in several ways besides lowering cholesterol.
NCEP recommends the following lifestyle changes:
Diet and exercise remain the first-line treatment option for high cholesterol in those at low to moderate risk for heart disease. And, most certainly, they are measures of prevention that everyone should heed.
If you are concerned about your cholesterol levels and your risk for heart disease, talk to your doctor. There are steps that you can take to reduce the risk.
Statins are often prescribed for high cholesterol. They are designed to be used in combination with lifestyle therapy. Statins works by blocking an enzyme (HMG-CoA reductase) that helps the body make cholesterol. The benefit from these medicines may also come from their anti-inflammation properties. Common examples of statins include:
Statin drugs have proven to be effective in reducing cholesterol levels. These medicines may also reduce the incidence of heart attack, stroke, and death.
