Table 3:

Acute pulmonary embolism risk stratification into high-, intermediate- and low-risk categories

		Shock or hypotension (SBP <90 mmHg)	Signs of RV dysfunction or abnormal cardiac biomarkers	sPESI*
High-risk		+	Both positive (although not needed for diagnosis in presence of shock)	≥1
Intermediate-risk	Intermediate-high	--	Both positive	≥1
	Intermediate-low	--	Either one or none positive	≥1
Low-risk		--	If assessed, both negative	0

^*Score one point for each: age >80 years, history of cancer, history of chronic obstructive cardiopulmonary disease, heart rate >110 beats per minute, systolic blood pressure <100 mmHg, oxygen saturation <90%
