1 Picking the P value
Use Agatston when available, segment count otherwise. Visual assessment is a fallback when calcium isn’t quantified.
| P value | Agatston | Segment count | Visual |
|---|---|---|---|
| P1 | 1–99 | 1–2 | mild |
| P2 | 100–299 | 3–4 | moderate |
| P3 | 300–999 | 5–7 | severe |
| P4 | ≥1000 | ≥8 | extensive |
