🫀 Coronary Perfusion Pressure (CPP)

UseWhen to use: shock / CPR / cath contexts when DBP and PAWP or LVEDP are available.

Loading calculator…

StrataLow coronary CPP narrows diastolic myocardial perfusion — raise DBP or reduce LVEDP as context allows.

LimitsWhen not to use: unreliable filling pressure. · Pitfall: CPR literature often uses aortic diastolic − RAP. · Not a stand-alone ischemia test.

Clinical takeaway

DBP − PAWP/LVEDP.

When to use

When to use: shock / CPR / cath contexts when DBP and PAWP or LVEDP are available.

How it works

Coronary CPP ≈ DBP − PAWP (or LVEDP).

Key points

  • DBP − PAWP/LVEDP.
  • Diastolic coronary gradient.
  • Next: MAP / SCAI stage.

Worked calculation

The values below come from this tool's own example placeholders and are computed server-side with the formula shown on this page, so the arithmetic can be checked quickly. It demonstrates how to substitute values only — it is not clinical advice and not a real case.

Diastolic BP60 mmHg
PAWP / LVEDP12 mmHg

  • DBP − PAWP：60 − 12
  • Cue：40–49 — intermediate / borderline band

FAQ

Frequently asked questions

Does Coronary Perfusion Pressure (CPP) upload patient data? Where is it calculated?
Calculation runs locally in the browser; inputs and results are not uploaded. For licensed clinicians only; interpret with history, investigations and local protocols — not a diagnosis or prescription.
How is Coronary Perfusion Pressure (CPP) calculated in practice? Can you show a worked example?
Inputs: Diastolic BP 60 mmHg, PAWP / LVEDP 12 mmHg → Result: Coronary CPP 48 mmHg（DBP − PAWP: 60 − 12, Cue: 40–49 — intermediate / borderline band）
