Risk Stratification in Pulmonary Embolism

The following are the principal markers useful for risk stratification:

• Clinical markers (shock, hypotension)
• Markers of RV dysfunction (RV dilatation, hypokinesis or pressure overload on echo, RV dilatation on CT, BNP elevation)
• Markers of myocardial injury (elevated troponin)

Patients with one or more of these markers have a higher mortality rate.
