High LDL? Here’s What REALLY Predicts Heart Disease...

The speaker reports on people with very high LDL (often >300 mg/dL) largely representing familial hyperlipidemia (FH). In a cohort of ~150 genetically affected people (LDL ≥190, sometimes up to 300), many did not develop premature heart disease: ~70% of women and ~50% of men with FH did not have early heart disease. The speaker states that LDL level itself was not a good predictor among FH patients; instead lipoprotein(a) (Lp(a)), fibrinogen, and metabolic dysfunction predicted risk. Low insulin and small waist circumference were associated with substantially lower relative risk—comparable to the healthiest people without FH. The speaker cites a BMJ Evidence-Based Medicine publication with coauthors for these findings.
