Introduction: Despite advances in therapeutic and diagnostic options, acute pulmonary embolism (PE) is associated with high morbidity and mortality. Risk classification is important in deciding how and where to treat patients This study aimed to investigate simplified pulmonary embolism severity index (sPESI) scores and highly sensitive troponin levels to predict 30-day clinical outcomes. Methods: Patients with the symptoms of dyspnoea, chest pain, and haemoptysis were included in the study. Multiple detector computed tomography (CT) examinations were performed. If the patients' glomerular filtration rate levels were less than 60 ml/min/1.73 m(2), then the ventilation/perfusion (V/Q) scan was the preferred imaging modality. Venous blood samples were collected to test for highly sensitive troponin T levels (Elecsys troponin T high sensitive, Roche diagnostics). All patients were examined by two-dimensional bedside echocardiography for detection of right ventricular dilatation. Patients' baseline characteristics (sex, ages, etc.) were recorded along with co-morbidities, symptoms, haemodynamic conditions, all-cause mortality rates during hospitalisation, the duration of hospital stay, radiographic test results, and laboratory findings, and electrocardiography were also obtained during emergency department admission. Primary outcome measure was defined as death in a month. Logistic regression model was created to reveal the associated parameters related to mortality within a month of the emergency department visit. Results: One hundred and seventy patients suspected of PE underwent either a CT angiogram or pulmonary V/Q scan. In total 70 patients were diagnosed with PE and included in the study. The logistic regression model was created in order to assess poor prognosis markers. In addition to the troponin levels and sPESI scores commonly used for pulmonary embolism prognosis, right ventricular dilatation, heart rate, systolic blood pressure and oxygen saturation using logistic regression models were created. Positive troponin level (odds ratio: 5.23 and 95% confidence interval [CI] 1.03 to 26.51) and negative sPESI score (odds ratio 2.14 and 95% CI 1.00 to 4.60) were found to be significant. Conclusions: Some scoring systems, including PESI and sPESI score, can be used for predicting mortality in patients with pulmonary embolism. If sPESI score is zero, and troponin levels are negative, the patient can be discharged safely.
