The retrospective analysis of the database of inpatients with the target assess the clinical course of PE according to prevalence, mortality, average duration of stay, risk factors, used diagnostic methods and kinds of therapy. Another aim of the study was a comparison of the dates among the survivors and deceased persons. We found the most important risk factors in the group of the deceased immobility (p<0.001)` heart failure (p<0.005) and stroke (p<0.01). On the contrary in the survivor group there were more frequent risk factors obesity (p<0.025); deep venous thrombosis (p<0.025) and tumors (p<0.05). Previous operations and traumas in the last month did not show any significant difference between both groups. Used treatment methods were evaluated, too. In the group of those who died predominated multi-morbidity, often frailty and geriatric giants even if the anticoagulant therapy was used comparably in both groups (survivors and the deceased).
