ESC CLASSIFICATION (2019)*

MASSIVE PE

HIGH-RISK PE

Hypotension, defined as a systolic blood pressure < 90 mm Hg, a drop of >40 mm Hg for at least 15 minutes, or need for vasopressor support

One of the following clinical presentations: cardiac arrest, obstructive shock, persistent hypotension (systolic BP < 90 mmHg or a systolic BP drop > _40 mmHg for >15 min

SUBMASSIVE PE

INTERMEDIATE RISK PE

Acute PE without systemic hypotension (systolic blood pressure > 90 mm Hg) but with either RV dysfunction or myocardial necrosis³

Acute PE without systemic hypotension (systolic blood pressure > 90 mm Hg) but with either RV dysfunction or elevated cardiac troponin levels³

Additionally, include PESI/sPESI criteria.

LOW-RISK PE

LOW-RISK PE

Acute PE and the absence of the clinical markers of adverse prognosis that define massive or sub-massive PE³

No RV dysfunction/no elevated cardiac troponins/normal PESI
