RV: right ventricle; LV: left ventricle; CT: computed tomography; BNP: brain natriuretic peptide; sPESI: simplified pulmonary embolism index; PE: pulmonary embolism.
* Persistent hypotension is defined as a systolic blood pressure <90 mmHg, need for vasopressors, or a decrease in the systolic blood pressure by ≥40 mmHg from baseline for 15 minutes or longer despite resuscitation.
¶ Other than contrast in the liver, chest CT is imprecise for RV assessment, especially when compared with echocardiography. In most cases, if feasible, CT findings of RV enlargement should prompt echocardiography.
Δ An sPESI score is calculated based upon a cumulative point system for age >80 years (1 point), history of cancer (1 point), chronic cardiopulmonary disease (1 point), pulse ≥110/min (1 point), systolic pressure <100 mmHg (1 point), and arterial oxygen saturation <90% (1 point); low-risk PE is a score of 0, while high-risk is any score >0.
◊ Although the obstruction index can be calculated, it is not a routine readout by radiologists and is more likely to be estimated gestalt.
