Hyperlipoproteinemias: Part II. Screening and patient classification

Area of Science:

• Cardiology
• Preventive Medicine
• Clinical Biochemistry

Background:

• The National Cholesterol Education Program (NCEP) guidelines recommend cholesterol screening for adults.
• Accurate cholesterol measurement is crucial for cardiovascular disease risk assessment.
• Current guidelines provide specific ranges for desirable, borderline-high, and high total cholesterol levels.

Purpose of the Study:

• To outline the current recommendations for cholesterol screening in adults.
• To define the established criteria for classifying serum cholesterol levels.
• To highlight the ongoing debate regarding optimal screening strategies for specific populations.

Main Methods:

• Review of the National Cholesterol Education Program (NCEP) guidelines.
• Definition of serum total cholesterol and LDL-cholesterol levels.
• Analysis of current recommendations for adult cholesterol screening.

Main Results:

• Total nonfasting serum cholesterol screening is recommended for all individuals 20 years of age or older.
• Desirable total cholesterol is <200 mg/dL, borderline-high is 200-239 mg/dL, and high is ≥240 mg/dL.
• LDL-cholesterol <130 mg/dL is considered desirable for further classification.

Conclusions:

• Current NCEP guidelines provide clear targets for adult cholesterol levels.
• The optimal approach for cholesterol screening in children and the elderly remains under discussion.
• Further research is needed to establish definitive screening recommendations for pediatric and geriatric populations.
