BMI 28 · BP 142/88 · LDL 168 · 30-year smoker (quit 2 yrs) · paternal MI at 49 · 'feels fine, runs 5K weekly'.
Contributing factors
  • CAC score 412 (Agatston, 90th percentile for age)+28
  • LDL 168 mg/dL (untreated)+18
  • 30 pack-year smoking history (quit 2 yrs)+14
  • Paternal MI at 49 (FDR <55)+12
  • BP 142/88 + BMI 28+6
Narrative

Marcus is firmly in the high-risk band. CACS >300 alone places 10-yr ASCVD risk >20%, regardless of pooled-cohort equation output. AHA/ACC 2018 Cholesterol Guideline mandates high-intensity statin + lipid clinic referral.

No intervention With OCTON Baseline US life table
EvidenceINTERHEART (Yusuf Lancet 2004, n=29,972) — 9 modifiable factors explain 90% of MI risk; they interact multiplicatively. CTT meta-analysis (n=170,000) + SPRINT (NEJM 2015) + PREDIMED (NEJM 2018) + DPP (Knowler NEJM 2002) + Doll smoking-cessation BMJ 2004 cohort + Khaw EPIC-Norfolk lifestyle-quartile Lancet 2018 stack across Marcus's profile to project a 28+ year recovery of life span versus the untreated trajectory — and ~8 years above the average US 52-yo who never had his risk factors.
How to actually realise the gain

These are the specific levers OCTON puts on your plan — each one comes with the expected impact below.

drug
High-intensity statin (atorvastatin 40 mg)
LDL 168 → <70; halves 10-yr MACE
drug
Aspirin 81 mg + BP meds (ACEi if BP>140/90)
Stroke + MI prevention
diet
Mediterranean / PREDIMED pattern
30% MACE reduction (PREDIMED, JAMA 2018)
exercise
Zone-2 cardio 150 min/wk + resistance 2×/wk
↓ resting BP, ↑ HDL, ↓ visceral adiposity
lifestyle
Sustained tobacco abstinence + 7 hr sleep
Halves residual smoking-attributable MACE

OCTON Impression · 92% confidence

Agatston coronary artery calcium score 412 (LAD 218, LCx 86, RCA 108). Severe coronary calcification consistent with established atherosclerosis. No critical luminal stenosis identified on contrast pass.

Findings
  • LAD proximal calcified plaque (Agatston 218) · Proximal LAD
  • LCx mid-segment calcified plaque (Agatston 86) · Mid LCx
  • RCA dominant artery calcified plaque (Agatston 108) · Distal RCA
  • No critical (≥70%) luminal stenosis on contrast review · All coronary segments
Differential diagnosis
  • Stable subclinical atherosclerosis (severe CAC)85%
  • Vulnerable plaque (non-calcified) co-existence10%
  • Tracking artefact / motion-induced calcium overestimate5%
Recommended actions
  • ▸Start high-intensity statin (atorvastatin 40 mg) — target LDL <70 mg/dL given CAC>300
  • ▸Lipid clinic referral within 2 weeks; consider ezetimibe + PCSK9i if LDL goal not met
  • ▸Aspirin 81 mg daily (CAC>100, bleeding risk acceptable)
  • ▸Cubicle quarterly HRV + BP monitoring; annual lipid panel
Caveats
  • CAC reflects calcified plaque burden — does NOT capture non-calcified vulnerable plaque.
  • Marcus is asymptomatic; stress test is NOT indicated unless symptoms develop.

What changed

The early-detection win

Marcus walked into the cubicle for a routine annual scan. He felt fine. Twenty minutes later, a coronary calcium score of 412 lit up an Agatston band that 96% of 52-year-olds never see. The Bayesian engine moved his 10-year ASCVD probability from 4.1% (pooled-cohort default) to 39.2% — a 9.5× lift. Untreated, his lipid panel + smoking + Stage-2 BP + impaired glucose stacked multiplicatively into a trajectory that would shorten his projected life by ~20 years — first MACE in his mid-50s. Same-day high-intensity statin + ASA + ACEi + smoking cessation programme + Mediterranean diet + 150 min/wk Z2. Two years later: LDL 64, BP 124/76, asymptomatic, tobacco-free. Marcus's likely first-MI age moved from his late 50s to his late 70s — a 28-year recovery of projected life and ~9 years above the average US 52-yo who never had his risk factors.
