What someone who reaches this rule is told

Word for word, as generated for the example person below. Figures in the text are theirs.

  • Reasonable to do

    Statin therapy is reasonable to start now.

    Your estimated 10-year PREVENT ASCVD risk is 4.9% (the "borderline" 3%–5% band), and you have risk-enhancing factors that tip that decision toward treatment: Elevated lipoprotein(a) — 78 mg/dL. The guideline says risk enhancers move a borderline-risk person toward a statin without needing further testing.
