It acts quickly and is often overlapped for several days with an oral anticoagulant, such as warfarin, until it becomes effective, which can take days. Diagnosis and treatment of PE is guided by clinical probability scoring systems and tools for prognostic stratification and early mortality risk evaluation. Who is at risk of developing a pulmonary embolism (PE)? Acute PE, a pulmonary manifestation of a circulatory problem, is a serious condition caused by obstruction of blood flow in one or more pulmonary arteries (PA).
