Bova Score for Pulmonary Embolism Complications

Stratifies normotensive (hemodynamically stable) patients with confirmed acute pulmonary embolism into three stages of increasing 30-day PE-related complication and mortality risk; applies only to non-hypotensive PE (a systolic BP < 90 mmHg means high-risk PE and falls outside this score).

Systolic blood pressure

Heart rate (bpm, 20–300)

Cardiac troponin (I or T) above the assay reference limit

RV dysfunction (echo RV/LV ratio > 0.9, sPAP > 30 mmHg, RV free-wall hypokinesis, or RV dilatation; OR CT RV/LV ratio > 1) — any one
