Zwolle Primary-PCI Risk Score
Zwolle primary-PCI risk score (De Luca 2004): Killip class, post-PCI TIMI flow, age ≥ 60, three-vessel disease, anterior MI, and ischemic time > 4 h sum to 0–16; ≤ 3 marks a low-risk early-discharge candidate.

Example
- Killip class
- III–IV (edema / shock)
- Post-PCI TIMI flow
- 0–1 (no/minimal)
- Age
- 70 years
- Three-vessel disease
- Yes
- Anterior infarction
- Yes
- Ischemic time > 4 hours
- Yes
Result: Zwolle 16 — high risk.

What the result means
- Bands
- ≤ 3 low (early-discharge candidate; 30-day mortality ~0.1–0.2%), 4–6 intermediate, ≥ 7 high.
What you enter
- Killip class
- Post-PCI TIMI flow
- Age
- Three-vessel disease
- Anterior infarction
- Ischemic time > 4 hours
How this is calculated
- Inputs
- Killip (I 0 / II 4 / III–IV 9), post-PCI TIMI flow, age ≥ 60, three-vessel, anterior MI, ischemic time > 4 h — total 0–16.
