VIDEO LESSON
ApoB
• Best measure of atherogenic particle burden, especially with high triglycerides, diabetes or obesity
• ApoB of 130 mg/dL or higher is a risk-enhancing factor in the 2018 ACC/AHA guideline
• Non-HDL cholesterol is a reasonable surrogate
Lp(a)
• Measure at least once in adulthood
• Levels of 50 mg/dL or 125 nmol/L or higher are risk-enhancing
• Use to intensify ApoB lowering and address other risk factors
Pearls
Coronary artery calcium scoring can refine risk when decisions are uncertain.
