Pulmonary Embolism: Multifunctional Assessment of Prognosis

This is a prospective, observational, multicenter study. The primary aim of the study is to assess the accuracy of spiral CT scan to detect right ventricular dysfunction as compared to current 'gold standard'in patients with pulmonary embolism. At the purpose of this study right ventricular dysfunction as assessed by transthoracic echocardiography and serum levels of troponin are considered as gold standard. The secondary aim of the study is to assess the prognostic value of right ventricular dysfunction as assessed by spiral CT scan.
