    Background And ObjectivesPulmonary embolism (PE) has a major burden of morbidity and mortality, consequently the need for a prompt risk stratification for these subjects is crucial. In order to evaluate the risk management and final disposition of patients with PE in the Emergency Department (ED), we conducted a study that was divided in two phases: Phase I retrospective study (RS), Phase II prospective study (PS).Materials And MethodsIn Phase I, 291 patients were enrolled while in Phase II, 83 subjects were evaluated. In both study phases, the enrolled subjects were analyzed for final disposition in ED using PESI score, right ventricle (RV) imaging, and high-sensitive cardiac troponin I (hs-cTnI) data. The RS patients were divided into low risk and high risk according to the sPESI score, while PS patients were grouped in low, intermediate, and high risk classes according to PESI score. In both study phases, all the studied patients were further divided into negative (hs-cTnI-) or positive (hs-cTnI+) groups according to hs-cTnI levels within normal or above cutoff values, respectively. For all enrolled subjects, CT pulmonary angiography was analyzed to assess the RV/LV diameter and volume ratio as an indicator of RV involvement.ResultsIn both RS and PS phases, hs-cTnI+ group showed a higher PESI score. Nevertheless, a significant percentage of hs-cTnI+ patients resulted to be in the low-risk PESI class. Patients with a positive RV/LV ratio were more likely to have a hs-cTnI+ (p < 0.01), while among those with a negative ratio, 24 to 32% showed as hs-cTnI+. In the hs-cTnI+ group from both study phases, patients were more likely to be admitted in an ICU (RR 3.7, IC: 2.1-6.5).ConclusionsIn conclusion, in patients with PE in the ED compared PESI score alone, the combination of hs-cTnI and PESI seems to be of greater utility in improving risk stratification and final disposition decision-making.
