Overview

PAOI >47% may aid CTPA risk stratification in acute PE; leaves open prospective validation against outcomes.

Structured PICO

Does CTPA-derived PAOI and RV/LV ratio effectively stratify risk in patients with acute pulmonary embolism?

P
Population
150 patients with acute pulmonary embolism (APE) proven by CTPA
I
Intervention
Computed tomography pulmonary angiography (CTPA) for risk stratification using pulmonary artery obstruction index (PAOI) and right to left ventricular (RV/LV) diameter ratios
O
Outcome
Risk stratification based on PAOI and RV/LV diameter ratiossurrogate

CTPA-derived pulmonary artery obstruction index (PAOI) and RV/LV ratio can effectively stratify risk in patients with acute pulmonary embolism.
