REVEAL Lite 2 (PAH risk)
REVEAL Lite 2 (Benza 2021): a simplified pulmonary-arterial-hypertension risk score (1-14) predicting 1-year mortality from six routinely collected variables.

Example
- eGFR
- 72
- WHO functional class
- Class III (+1)
- Systolic BP
- 104
- Heart rate
- 88
- 6-minute walk distance
- 300
- BNP / NT-proBNP band
- BNP >= 800 / NT-proBNP >= 1100 pg/mL (+2)
Result: REVEAL Lite 2 total 10 (1-14): high risk (1-year mortality 25.1%).
The tool opens with these values already filled in. Replace them with your own.
What the result means
- Bands
- low 1-5 (2.9% 1-year mortality), intermediate 6-7 (7.1%), high >= 8 (25.1%).
What you enter
- eGFR (mL/min/1.73 m^2)
- WHO functional class
- Systolic BP (mm Hg)
- Heart rate (beats/min)
- 6-minute walk distance (m)
- BNP / NT-proBNP band
How this is calculated
- Variables
- from a base of 6: renal insufficiency, WHO functional class, systolic BP, heart rate, 6-minute walk distance, and a BNP/NT-proBNP band, summed to 1-14.
