Essentials
- •
Predicting chronic thromboembolic pulmonary hypertension (CTEPH) after pulmonary embolism is hard.
- •
We studied 772 patients with pulmonary embolism who were followed for CTEPH (incidence 2.8%).
- •
Logistic regression analysis revealed 7 easily collectable clinical variables that combined predict CTEPH.
- •
Our score identifies patients at low (0.38%) or higher (10%) risk of CTEPH.
