Area of Science:

• Cardiology
• Preventive Medicine
• Clinical Practice Guidelines

Background:

• Atherosclerotic cardiovascular disease (ASCVD) remains a leading cause of mortality.

• To provide evidence-based recommendations for cholesterol management to reduce ASCVD risk in adults.

Main Methods:

• Systematic review of randomized controlled trials (RCTs) and meta-analyses of RCTs.
• Evaluation of ASCVD outcomes to inform recommendations.
• Synthesis of evidence to guide clinical decision-making.

Main Results:

• Recommendations cover lifestyle modifications, statin therapy intensity, and patient selection for primary prevention.
• Guideline addresses safety, monitoring, and the use of non-statin therapies.
• Identifies patient groups most likely to benefit from statin therapy.

Conclusions:
