Pulmonary embolism is a common disease associated with high mortality. Death due to pulmonary embolism occurs mainly before hospital admission or in the first hours of the hospital stay. Prompt diagnosis and prognostic stratification and more intensive treatment in patients with estimated high risk for adverse outcomes have the potential to reduce mortality due to pulmonary embolism. Significant advances have recently been made in the risk stratification for adverse outcomes in patients with pulmonary embolism and normal blood pressure. In these patients, right ventricle overload assessed by echocardiography and probably by helical computerized tomography is a predictor of in-hospital mortality. Serum troponin is rapidly available in the emergency room, and has a critical role in the management of patients with acute coronary syndromes. The role of serum troponin in patients with pulmonary embolism has been explored recently: it seems to be marginal in diagnosis while it can significantly contribute to prognostic stratification. Elevated serum levels of troponins are associated with right ventricular overload and adverse in-hospital outcomes in patients with pulmonary embolism and normal blood pressure.
