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% ↵a The Bova score predicts the 30-day risk of complications and death in hemodynamically stable patients. Complications include hemodynamic collapse and recurrent nonfatal pulmonary embolism.
Based on information in reference 4.
Pulmonary embolism severity index (PESI) class III to V, or simplified PESI score ≥ 1 Right ventricular dysfunction or strain on computed tomographic angiography Sinus tachycardia (heart rate > 100 beats per minute) Persistent bradycardia (heart rate < 40 beats per minute) Elevated cardiac troponin or N-terminal pro-B-type natriuretic peptide New complete or incomplete right bundle branch block Changes in anteroseptal ST segment or T wave
