A mechanism-based operational definition and classification of hypercholesterolemia

Area of Science:

• Cardiovascular Medicine
• Clinical Biochemistry
• Medical Diagnostics

Background:

• Clinical guidelines strongly recommend lipid-lowering treatments but lack a definitive diagnostic definition for hypercholesterolemia and its subtypes.
• Clinicians often conflate guideline indications for hypolipidemic treatment with a general, non-specific sense of hypercholesterolemia.

Purpose of the Study:

• To propose a unified definition and a mechanism-based classification for hypercholesterolemia.
• To provide a framework for stratifying patients and guiding efficient diagnosis.
• To ensure the proposed classification does not interfere with current Atherosclerotic Cardiovascular Disease (ASCVD) risk reduction strategies.

Main Methods:

• Review and synthesis of existing literature on hypercholesterolemia definitions and classifications.
• Development of a novel, mechanism-based classification system.
• Alignment of the proposed definition and classification with current clinical practice and ASCVD risk reduction guidelines.

Main Results:

• A proposed unified definition of hypercholesterolemia is presented.
• A novel mechanism-based classification system for hypercholesterolemia subtypes is introduced.
• The proposed framework is designed to aid in patient stratification and diagnostic efficiency.

Conclusions:

• A clear, unified definition and classification are needed for hypercholesterolemia.
• The proposed mechanism-based approach facilitates precise diagnosis and patient stratification.
• This framework supports efficient clinical decision-making in managing hypercholesterolemia and reducing ASCVD risk.
