Diagnosis and case finding in familial hypercholesterolemia

Area of Science:

• Cardiology
• Genetics
• Public Health

Background:

• Heterozygous familial hypercholesterolemia (hFH) significantly elevates coronary disease risk.
• Despite its risks, hFH diagnosis and case finding face challenges.

Purpose of the Study:

• To evaluate if hFH meets World Health Organization criteria for screening.
• To identify barriers in current hFH screening strategies and propose solutions.

Main Methods:

• Review of existing hFH identification strategies.
• Analysis of barriers hindering screening implementation.
• Assessment of hFH against WHO screening criteria.

Main Results:

• hFH meets WHO criteria for a screening program.
• Current strategies (e.g., universal cholesterol testing, family screening, premature event screening) are largely unsuccessful in identifying hFH cases.
• Significant barriers exist for both patients and physicians in executing screening recommendations.

Conclusions:

• hFH warrants a dedicated screening approach due to its high cardiovascular risk.
• Existing screening strategies are insufficient for widespread hFH case detection.
• Overcoming barriers, including enhancing primary care provider awareness, is crucial for effective hFH identification.
