Scores for risk stratification of normotensive pulmonary embolism

Score	Bova score [8, 9]		Modified FAST score [10]
Items (points)	Elevated cardiac troponin	2	Elevated cardiac troponin	1.5
	RV dysfunction (TTE or CT)	2	Syncope	1.5
	Heart rate ≥ 110 bpm	1	Heart rate ≥ 100 bpm	2
	Systolic blood pressure 90–100 mmHg	2
Risk classes
Low risk	0–2 points		< 3 points
Intermediate-low risk	3–4 points		–-
Intermediate-high risk	> 4 points		≥ 3 points
