Estimation of individual risk and choice of initial therapeutic approach for patients with pulmonary embolism (PE) remains controversial. The three key components for risk stratification in PE are clinical evaluation, cardiac biomarkers and assessment of right ventricular size and function. The aim of this study was to assess the ability of admission troponin I (TnI) levels to predict short-term mortality and complicated clinical course in patients with PE. ⋯ Elevated TnI levels are associated with higher risk for in-hospital mortality and complicated clinical course. Additional studies are needed to assess whether troponin levels, alone or in conjunction with other tests, can be used to guide therapeutic strategy and improve the prognosis of patients with PE.
