d-Dimer and simplified pulmonary embolism severity index in relation to right ventricular function.
Right ventricular (RV) involvement in pulmonary embolism (PE) is an ominous sign. The aim of this study was to investigate the extent to which the d-dimer level or simplified PE severity index (sPESI) indicates RV dysfunction in patients with preserved systemic arterial pressure. ⋯ In the acute stage of PE, a d-dimer level 3 mg/L or higher may identify nonmassive PE patients with RV dysfunction and thereby help to determine their risk profile. We found no additional value for sPESI in this context.
