Bova scoring system for estimating 30-day risk of complications or death in acute pulmonary embolism
| Predictor variable | Points |
|---|---|
| Systolic blood pressure 90–100 mm Hg | 2 |
| Elevated cardiac troponin | 2 |
| Right ventricular dysfunction on echocardiography or computed tomography | 2 |
| Heart rate ≥ 110/min | 1 |
| Points a | Stage | 30-day risk of complicationsa | 30-day risk of death |
|---|---|---|---|
| 0–2 | I | 4.4% | 3.1% |
| 3–4 | II | 18% | 6.8% |
| > 4 | III | 42% | 10% |
