Treat now; the score sets the goal — any calcium → LDL <100, ≥100 → <70, ≥300 → <55 optional

What someone who reaches this rule is told

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

  • Strongly recommended

    Your CAC score of 140 supports starting lipid-lowering therapy now, aiming for LDL-C below 70 mg/dL (and non-HDL-C below 100).

    Any coronary calcium at borderline or intermediate risk supports treating rather than waiting, and the score itself sharpens the target: any calcium supports a goal of 100, and 140 being at or above 100 supports 70. One thing to know before any repeat scan: a statin that is working reliably raises this number, because the score weights density and treatment makes plaque denser. A higher score later is not a reason to stop the statin.

“Borderline risk, calcium found, hs-CRP raised” — an illustrative profile, not a real user.

Their path through cholesterol

  1. Known ASCVD (prior heart attack, stroke, or revascularization)?No
  2. Your situation (severe hypercholesterolemia short-circuits the risk score)10-yr risk 3–5% (borderline)
  3. A risk-enhancing factor that counts? (weighted — a single unconfirmed hs-CRP does not count until repeated)None on record
  4. Coronary artery calcium (CAC) score? (further testing beyond basic labs)Above 0 ← this rule
  5. hs-CRP ≥2 mg/L, confirmed on a repeat test? (further testing beyond basic labs)Yes

Being tested further

A trial that could change this, still running or reported too recently to be settled.

  • The Optimal Trial — Once someone has coronary calcium, does adding a CT coronary angiogram — which shows narrowings and soft plaque, not just calcium — actually change how they're managed, and for the better?

What we are least sure of here

  • Q14Is the calcium-paradox warning — statins raise the score — stated strongly enough?
