• stratifies PE patients into 5 severity classes with varying 30 day mortality:
  • class I score < 65: < 1.7% mortality
  • class II score 66-85: 1.7-3.5% mortality
  • class III score 86-105: 3.2-7.1% mortality
  • class IV score 106-125: 4-11.4% mortality
  • class V score > 125: 10-24.5% mortality

• Arch Intern Med. 2010 Simplification of the pulmonary embolism severity index for prognostication in patients with acute symptomatic pulmonary embolism.

High risk and 8.9% mortality rate if ANY of:

• age > 80yrs
• PH cancer
• PH chronic lung disease
• HR >= 110
• Systolic BP < 100mmHg
• Sa O2 < 90%

Otherwise “Low Risk” and thus:

• 1.1% mortality
• 1.5% of recurrent VTE or non-fatal bleeding
