Key result
Shock index, SBP <100 mmHg, and SBP <90 mmHg independently predicted 30-day mortality in acute PE; shock index had the highest sensitivity (30.5%) and SBP <90 mmHg the highest specificity (96.6%).

Does the shock index or systolic blood pressure better predict 30-day mortality in patients with acute pulmonary embolism?
In patients with acute pulmonary embolism, the shock index is a more sensitive but less specific predictor of 30-day mortality compared to systolic blood pressure thresholds of <100 or <90 mmHg.
Otero et al. (2007) conducted an observational in acute pulmonary embolism (n=6,599). Shock index and systolic blood pressure <100 mmHg or <90 mmHg was evaluated on 30-day mortality. Shock index, SBP <100 mmHg, and SBP <90 mmHg independently predicted 30-day mortality in acute PE; shock index had the highest sensitivity (30.5%) and SBP <90 mmHg the highest specificity (96.6%).
