Uncontrolled Cholesterol in Individuals with Severe Hypercholesterolemia in a Health Evaluation Program in Brazil.

Area of Science:

• Cardiology
• Metabolic Disorders
• Public Health

Background:

• Severe hypercholesterolemia (SH) confers a high risk of atherosclerosis.
• Intensive lipid-lowering therapy is recommended, targeting LDL-C reduction of ≥50% and levels <70 mg/dL.

Purpose of the Study:

• To evaluate cholesterol control in individuals with SH (LDL-C ≥ 190 mg/dL or 160-189 mg/dL on lipid-lowering drugs).
• Assessed achievement of recommended LDL-C goals within a health evaluation program.

Main Methods:

• Analysis of 55,000 individuals, identifying 2,214 (4%) with SH.
• 1,016 individuals had repeated assessments over a mean follow-up of 4.1 years.
• Primary endpoint was the achievement of recommended LDL-C goals.

Main Results:

• Mean LDL-C was 203.0±22.0 mg/dL; only 19% were on lipid-lowering drugs initially.
• Lipid-lowering drug use increased to 48.4% over follow-up, with a mean LDL-C reduction of 26.7%.
• Only 19.2% achieved ≥50% LDL-C reduction, and merely 3.1% reached <70 mg/dL.

Conclusions:

• A significant disparity exists between recommended SH treatment guidelines and actual clinical practice.
• Current management strategies are insufficient to achieve target LDL-C levels in a high-risk population.
